Options

What Are Options?

Options are financial contracts giving their buyers the right, not obligation, to buy (Call) or sell (Put) an asset — stocks, commodities — at a predetermined price and on an agreed-upon date.

Used for: Speculation Hedging Risk Management

  • BUY → Call Option
  • SELL → Put Option

Key Terms

Strike Price: The predetermined price to buy/sell the underlying asset.

Expiration Date: The date on which the contract expires. Involved parties should honour the contract before this date.

Premium: The cost one must pay to buy an option contract.

Exercise Styles

European Expiration: Options can be exercised only on expiration.

American Expiration: Can be exercised anytime before expiration.

Call Option

Call options give the holder the right but not the obligation to buy the underlying asset at a predetermined agreed-upon price and date.

  • Call has a bearish Seller and a bullish Buyer

Put Option

Put options is a contract giving the holder the right to sell but not the obligation to sell an asset at a set price before a specific expiry date. Buyers must pay a premium to buy a contract.

  • Put → bearish buyer / bullish seller

Points to Note

Cost = Current Market Price × No. of Shares × Premium

Buyers are bearish and they anticipate the stock prices will rise in the market and they aim to make profit by buying the stock at a price lesser than the current market price and aim to sell the stock at a price higher than the current market price. Or simply sell the contract itself.

Put — Seller's POV

Seller receives the premium and has a notion that the market will be bearish and expects to buy an asset for price lower than the current market price. Seller has the obligation to buy the asset at the market price regardless of how the market moves.

Options Contract
ELI5It's like putting a deposit on a house. You pay a small fee to lock in the right to buy it at today's price — but you don't have to buy it if you change your mind.
A derivative giving the buyer the right, not obligation, to buy or sell an underlying asset at a specified strike price on or before expiration. The seller is obligated to fulfill the trade if exercised.
ExampleYou pay a $5 premium for the right to buy Apple at $150. If Apple hits $180, you exercise and pocket $25. If it drops to $120, you let it expire — losing only the $5 premium.
Intrinsic vs Time Value
ELI5Intrinsic value is the profit you'd make RIGHT NOW if you exercised. Time value is the extra you pay because anything could happen before expiry.
Intrinsic Value = max(S−K, 0) for calls; max(K−S, 0) for puts. Time Value = Premium − Intrinsic Value. Time value decays to zero at expiry (theta decay). Volatility inflates time value.
ExampleCall with K=$100, S=$110, premium=$14. Intrinsic = $10. Time Value = $4. As expiry nears, that $4 erodes — even if the stock stays at $110.
American vs European Style
ELI5American: cash out your winning lottery ticket any time before deadline. European: cash it only on the exact deadline day.
American: exercisable anytime up to expiry — more flexible, typically more expensive. European: exercisable only on expiry date. Most index options (SPX, Nifty) are European; most equity options are American.
ExampleYou hold an American call on NIFTY. It shoots up 3 weeks before expiry — you exercise immediately and lock in profit. A European holder must wait until expiry regardless.

Trade Life Cycle

Front Office — Decision Making & Execution

1. Trade Initiation & Planning: Portfolio managers or traders decide to trade based on research, strategy, or market signals.

2. Trade Agreement: Key terms like price, quantity, and instrument are agreed upon between buy side and sell side.

3. Trade Execution: Trade is routed to an exchange and matched with the corresponding buy or sell order.

4. Trade Capture: Executed trades are captured in internal systems for downstream users in the back office to match with during Trade Validation.

Middle Office — Accuracy, Compliance, Readiness

Ensures the trade is accurate, compliant, and is ready to be settled.

Trade Enrichment: Adding crucial data to enable smooth settlement — SSI (Standard Settlement Instructions), custodian details, fees, identifiers. Often via static data. Key post-capture, pre-validation step ensuring accurate information (settlement bank details, market codes, cash values) is ready for middle & back offices.

SSI (Standard Settlement Instructions): Pre-agreed details (Bank name, account number, SWIFT code) that specify where payments and securities must be delivered — acting as an address for financial transactions in the trade life-cycle.

Trade Validation: Checks for completeness, risk limits, and regulatory compliance. Acts as a quality check to confirm trade details (security, quantity, price, counterparty); match front office records and comply with internal & regulatory rules (e.g.: no restricted securities are being traded).

Back Office — Settlement & Records

1. Clearing: Central clearing house acts as intermediary — matching and confirming trade details, calculating obligations, managing risk via collateral, becoming buyer to every seller and seller to every buyer (Novation).

Novation: Clearing house becomes the central counterparty, eliminating counterparty risk and managing default risk through margin and collateral.

2. Trade Settlement: Final exchange of securities and cash. Ownership officially transfers between counterparties typically on a set date (T+1, T+2) based on market rules.

Settlement Timing: India → T+1 US → T+1 Canada → T+3

Trade Reconciliation: Crucial risk management step verifying internal records match external ones (Brokers, Custodians, Clearinghouses) to catch possible errors. Ensures accuracy; reduces risk; meets compliance by resolving discrepancies.

Accounting & Final Reporting: Trades are booked; P&L is calculated and regulatory reports are filed.

Counterparty Risk

Counterparty is the other party in a financial/contractual transaction.

Counterparty Risk is the possibility that the other party in a financial agreement will fail to meet their contractual obligations.

Trade Reporting

Internal and Regulatory Reporting post execution — trade time, price, quantity. Trade transaction details are sent to regulators (SEBI, SEC) to ensure transparency, compliance and is maintained.

Trade Life Cycle (Overview)
ELI5Like buying something on Amazon: search & click buy (initiation), confirm order (agreement), process it (execution), pack it (enrichment), check legality (validation), ship via courier (clearing), deliver to door (settlement).
The complete journey of a trade from investment decision to final settlement and reconciliation. Spans Front Office (deal-making), Middle Office (risk & compliance), and Back Office (settlement & accounting).
ExampleFund manager buys 10,000 Infosys shares → exchange match → captured in OMS → enriched with SSIs → validated → cleared via NSE clearinghouse → settled T+1 → booked in accounting system.
Novation & Central Clearing
ELI5You and a friend bet through a bookie. The bookie steps between you — now you both owe the bookie. If your friend defaults, the bookie covers it. You're protected.
The CCP (Central Counterparty Clearing House) legally substitutes itself as buyer to every seller and seller to every buyer. It manages default risk through initial margin, variation margin (daily MTM), and default funds. Members are protected from bilateral counterparty failure.
ExampleYou sell futures to Bank A. After novation: you owe NSE Clearing Corp, Bank A is owed by NSE Clearing Corp. If Bank A defaults, you are fully protected — NSE's default fund covers it.
T+1 / T+2 Settlement
ELI5T is the day you buy the stock. T+1 means money and stock officially change hands the next business day.
Settlement lag is business days after trade date when cash and securities officially transfer. India moved to T+1 in 2023. The US moved to T+1 in May 2024 (from T+2). Shorter settlement reduces counterparty risk and frees up capital.
ExampleYou buy 100 Reliance shares Monday (T). Under T+1, shares appear in your demat Tuesday morning and the seller receives cash Tuesday — reducing 24 hours of credit risk vs the old T+2 cycle.
Trade Reconciliation
ELI5Like checking your bank statement against your own spending diary — making sure both tell exactly the same story, every single day.
Matching a firm's internal trade records against external records from brokers, custodians, and clearinghouses. Breaks (mismatches) must be investigated. Critical for regulatory compliance (MiFID II, Dodd-Frank) and risk management. Typically run end-of-day and intra-day.
ExampleYour OMS shows 500 HDFC shares at ₹1,600. Custodian statement shows 500 at ₹1,602. Reconciliation team flags a ₹1,000 break, investigates whether it's rounding or a genuine booking error, and resolves before settlement.
Topic 03
Swaps

What is a Swap?

A Swap is a derivative contract by which two parties consent to exchange the cash flows/liabilities from two different financial instruments. Swaps usually involve cash flows based on a notional principal amount.

Swaps are traded over the counter — negotiated and executed directly between two parties, allowing more flexibility and customisation. Parties tailor the contract to their specific risk management strategies.

SEFs (Swap Execution Facilities): Trading platform allowing many market participants to execute swaps in a transparent, regulated environment in the U.S.

Interest Rate Swap

Agreement between two parties to exchange interest payments for a set length of time on a specific notional amount. Two types:

  • Fixed Rate: One party pays a fixed interest rate on the notional principal. Rate remains constant throughout the swap term.
  • Floating Interest: Agrees to pay a floating interest rate on the notional principal amount (e.g. SOFR, ESTRON).

Credit Default Swap (CDS)

A CDS is a derivative contract that allows one party (usually an investor/lender) to swap or offset their risk associated with a debt instrument like a bond/loan with that of another party.

To swap the risk, the lender purchases a CDS from a third party who agrees to reimburse the lender if the borrower ends up defaulting. The individual who purchases the CDS pays protection premiums to the other party.

Interest Rate Swap (IRS)
ELI5Two friends swap lunch deals — one always has a fixed $10 sandwich, the other gets whatever the cafeteria charges that day. They swap so each gets what suits them better.
One party pays fixed rate, receives floating (SOFR/LIBOR equivalent) from the counterparty. Notional principal never exchanges hands — only interest cash flow differences are paid. Used to hedge rate exposure or speculate on rate movements.
ExampleCompany A has $10M floating loan at SOFR+2%, fears rates rising. Enters IRS: pays fixed 6%, receives SOFR+2% from Bank B. Net cost is locked at 6% regardless of SOFR movements — perfect hedge.
Credit Default Swap (CDS)
ELI5You lend money to a risky borrower. You buy insurance — a CDS — from someone else. If your borrower can't pay, the insurance company pays you instead.
The protection buyer pays periodic premiums; the protection seller compensates for losses if a credit event occurs (default, bankruptcy, restructuring). CDS can hedge credit exposure or speculate on creditworthiness. Famous in the 2008 financial crisis (synthetic CDOs).
ExampleA bank holds $50M in risky corporate bonds. Buys a CDS for 200bps/year ($1M premium). Corporation defaults → CDS seller pays $50M face value. Bank is made whole. Without CDS: total loss on bonds.
Topic 04
Futures & Forwards

Futures

Futures are derivative contracts whose value comes from changes in the price of the underlying asset. They are standardised legal agreements to buy or sell an asset at a predetermined date and price — obligating both buyer and seller.

Used primarily for hedging against price movements and speculation.

Method of Settlement

  • Physical delivery — if underlying are commodities (Oil, Gold, Wheat)
  • Cash settlement — if underlying is Index, Stocks

Underlying Assets

  • ★ Equities Futures
  • ★ Stock index futures (VAS, S&P500)
  • ★ Commodity futures → Oil, Gold, Natural gas
  • ★ Currency Futures

Futures are Standardised; traded on Exchanges — thereby minimizing Counterparty Risk.

Forwards

Forward contract is an OTC instrument, customised between two parties to buy or sell an asset at a specified price on a future date. Offer flexibility but come with high default risk due to their non-standardised nature and lack of a Centralised Clearing House.

Futures Contract
ELI5A farmer promises to sell 1,000kg of wheat to a bakery in 3 months at today's price. Both sides are locked in — neither can back out. That's a futures contract.
Standardised, exchange-traded agreement obligating both parties. Clearing houses eliminate counterparty risk via daily margining. Initial margin required upfront; variation margin settles daily P&L. Open interest tracks total outstanding contracts.
ExampleCrude oil futures on MCX: 100 barrels at ₹6,500/barrel, delivery June. Oil rises to ₹7,000 → buyer profits ₹50,000; falls to ₹6,000 → seller profits ₹50,000. P&L settled daily.
Forwards vs Futures
ELI5Futures = buying a standardised box of chocolates from a big store with a return policy. Forwards = ordering a custom chocolate box from a friend — flexible, but if they bail, you're stuck.
Forwards are OTC, customisable, settle on expiry, no daily margining, high counterparty risk. Widely used in FX markets by corporates to hedge currency exposure. Forwards don't require upfront margin but carry full bilateral default risk.
ExampleIndian IT company expecting $1M in 6 months enters a USD/INR forward with their bank at ₹84/USD. Rupee strengthens to ₹80 — they still get ₹84M as contracted. The bank bears the FX risk.
Topic 05
Mark-to-Market

What is Mark-to-Market?

Mark to market is a financial accounting method that values assets and liabilities at their current market price; reflecting real time changes — providing a more accurate financial picture than historical cost.

Also involves daily settlement of profits/losses on open derivative positions like futures to manage risk and ensure sufficient margin.

Key Aspects of MTM

Futures/Derivatives: For open future contracts, MTM calculates daily profits/losses based on the closing price; settling these amounts into/out of the traders account each day.

Valuation: Assets are valued at their last traded or Settlement price.

Transparency: Offers a clear view of an investment's current financial health.

Risk Management: Helps identify potential risks and manage exposures.

Performance: Allows investors and fund managers to measure strategy success against current market conditions.

Mark-to-Market (MTM)
ELI5If you bought a house for $200K but it's now worth $350K, mark-to-market says your asset is worth $350K today — not what you paid. Every day, everything gets re-priced.
Accounting methodology valuing financial instruments at current fair market value rather than historical cost. For trading books: provides accurate P&L picture. For derivatives: drives daily settlement amounts and margin calls. Required under IFRS 9 and US GAAP ASC 820.
ExampleBank holds $10M in corporate bonds, originally bought at $9.8M. Current market value $10.3M → MTM shows a $500K unrealised gain recognised on books immediately. Next day prices drop to $9.9M → $400K unrealised gain booked.
Variation Margin & Margin Calls
ELI5You're gambling at a casino with borrowed chips. Lose too much and they demand you top up immediately — or they close your bet.
Daily MTM losses reduce the margin account. When it falls below the maintenance margin level, a margin call is issued — requiring deposit of additional funds (variation margin) by next morning or forced position liquidation occurs. Protects the clearing house from member defaults.
ExampleTrader has $10,000 initial margin. Bad week brings account to $5,000 — below $7,000 maintenance margin. Margin call issued: deposit $2,000 by 9am or positions liquidated at market open.
Topic 06
SWIFT / BIC / IBAN

BIC — Bank Identifier Code

BIC functions like postal codes for banks, assigned by the SWIFT network. Each bank has a unique SWIFT/BIC Code for precise routing.

SWIFT

Secure standardised instructions sent between financial institutions globally via the Society for Worldwide Interbank Financial Telecommunication network, enabling international payments and transactions. Swift itself doesn't transfer funds — it carries the messages. Unique BIC Codes identify banks for secure, efficient, traceable cross border financial communication.

SWIFT Code Structure

8–11 characters: Bank Code → 4 letters Country Code → 2 letters Location → 2 letters/numbers Branch Code → 3 chars (optional)

IBAN

Internationally standardised account number code that specifically identifies every account within the system. Consists of minimum of 15 characters. Combines local A/c number formats with additional info such as Country ID. Foreign transfers cannot be processed without an IBAN.

MT Legacy vs ISO 20022

The MT legacy messaging standards are decommissioned effective Nov 2025. Cannot support high volume of deals required. New message format → ISO 20022. New standard provides faster, more transparent cross border payments — designed to work in near real time. Older MT → 25 BDs to deliver.

SWIFT Network
ELI5SWIFT is like a super-secure WhatsApp for banks. Banks message each other saying "please send $1M to account X" — but the money travels through a different pipe. SWIFT is just the messenger.
Global cooperative messaging network used by 11,000+ financial institutions in 200+ countries. It doesn't move money — it carries instructions that trigger money movement through correspondent banking relationships. SWIFT messages are standardised, authenticated, and encrypted.
ExampleHDFC Mumbai sends $500K to Chase New York: HDFC sends SWIFT MT103 → HDFC's USD correspondent (Wells Fargo) receives instruction → routes to Chase → Chase credits beneficiary. SWIFT carried the message; Fedwire moved the money.
BIC / SWIFT Code
ELI5It's the bank's unique postal address on the SWIFT network — without it, your wire transfer is a letter without an address.
8–11 character unique bank identifier. Example: HDFCINBB = HDFC (bank) + IN (India) + BB (Mumbai). Mandatory for all cross-border wire transfers. Used by correspondent banks to route payment messages to the correct institution.
ExampleCITIUS33 = Citibank (CITI) + United States (US) + New York (33). When wiring internationally, this tells the entire banking network exactly where to route the funds — to the correct bank, in the correct city.
IBAN
ELI5Your regular account number is your name. IBAN is your full mailing address — country, bank, branch, and account all in one code that works internationally.
Standardised account identifier up to 34 characters. Includes country code (2), check digits (2), and bank account number. Mandatory for SEPA payments. The check digit mathematically validates the IBAN — catching typos before they cause payment failures.
ExampleGB29 NWBK 6016 1331 9268 19 — GB (UK), 29 (check digits validate the whole string), NWBK (NatWest sort code area), 601613 (sort code), 31926819 (account number). A single wrong digit triggers automatic rejection.

Message Types

MT103 — Single Customer Credit Transfer

Client → Beneficiary. Uses: Margin payments, Redemption, Client Settlements.

MT202 — General Financial Institution Transfer

Bank → Bank payment.

MT205 — Financial Institution Transfer (Execution)

Urgent / Same day interbank payments.

PACS.008 — FI to FI Customer Credit Transfer

Uses: Customer payments between banks. Replacement for MT103, MT202.

PACS.004 — Payment Return

Usage: Failed Settlement, Incorrect Beneficiary details, Compliance rejections.

PACS.028 — Payment Investigation Request

Enquiry or investigation related to a payment. Usage: Missing payment, Value date issues. Replacement for MT199.

MT103 vs PACS.008
ELI5MT103 is a fax. PACS.008 is a fully structured email with rich metadata — same job, infinitely more information, fully machine-readable.
MT103: SWIFT legacy message for customer credit transfers. Limited free-text fields; AML screening requires manual parsing. PACS.008: ISO 20022 replacement. Structured XML data — full names, addresses, LEI codes, purpose codes — enabling automated AML, faster STP (straight-through processing).
ExampleMT103 field 59 (beneficiary): "JOHN SMITH, 123 MAIN ST". PACS.008 equivalent: structured XML with <Nm>John Smith</Nm>, <StrtNm>Main Street</StrtNm>, <PstCd>SW1A</PstCd> — fully parseable by sanctions screening systems instantly.
PACS.004 — Payment Returns
ELI5The postal equivalent of "Return to Sender" — your payment couldn't be delivered, so it comes back with a reason code explaining why.
ISO 20022 message returning funds when a payment fails or is rejected. Carries structured reason codes (e.g., AC01 = incorrect account number, MS03 = not specified, BE04 = missing beneficiary address). Replaces manual MT199/MT299 investigation messages. Enables automated processing of failed payments.
ExampleYou send PACS.008 to Bank of America for beneficiary account XXXXXX. BofA can't find the account → sends PACS.004 return with reason code AC01 (IncorrectAccountNumber) within hours. Your ops team auto-processes the return and contacts client to correct details.

Market Data Sources

Bloomberg

Bloomberg Terminal (BLP) is the industry-standard platform for real-time market data, pricing, analytics, and news. Bloomberg Data License provides bulk data feeds to downstream systems. Key identifiers: BBGID (Bloomberg Global Identifier) — unique across all asset classes.

Used for: bond pricing, equity analytics, derivatives pricing, economic data, trade execution (Bloomberg TSOX, EMSX), FX rates, corporate actions, reference data.

Refinitiv (now LSEG Data & Analytics)

Formerly Thomson Reuters Eikon / Datastream. Major competitor to Bloomberg. Key identifiers: RIC (Reuters Instrument Code) — e.g., RELIANCE.NS for Reliance on NSE. Provides real-time feeds, historical data, reference data, analytics.

Products: Eikon Desktop, DataStream (historical), Elektron (real-time), World-Check (KYC/AML screening).

MarkIt (now part of S&P Global)

Specialises in OTC derivatives pricing and reference data. Key products: Markit RED (Reference Entity Database for CDS), MarkIt EDM (Enterprise Data Management), Markit iBoxx (bond indices), Markit BOAT (trade reporting).

Critical for CDS pricing, loan data, structured products valuation, and post-trade data for OTC derivatives.

ICE Data Services (IDC)

Interactive Data Corporation — now part of Intercontinental Exchange (ICE). Provides evaluated pricing for fixed income securities that don't trade frequently. Key services: ICE Bonds (trading), continuous evaluated pricing, reference data, market indices (ICE BofA bond indices).

Particularly strong for: corporate bonds, municipal bonds, mortgage-backed securities where live quotes are unavailable.

Other Key Providers

  • SIX Financial Information — European reference data, corporate actions, regulatory reporting data (SFDR, MiFID II)
  • FactSet — Portfolio analytics, earnings estimates, financial statements
  • Moody's Analytics / S&P Capital IQ — Credit ratings, risk analytics, private company data
  • MSCI — Equity indices, ESG ratings, risk models (Barra)
  • DTCC (Depository Trust & Clearing Corp) — Post-trade data, securities identifiers, trade repository

Security Identifiers

ISIN → International Securities Identification Number (12 chars, global) CUSIP → US & Canada (9 chars) SEDOL → London Stock Exchange (7 chars) FIGI → Financial Instrument Global Identifier (Bloomberg open standard) RIC → Reuters Instrument Code (Refinitiv) BBGID → Bloomberg Global Identifier
Bloomberg Terminal
ELI5Imagine Google Search, Excel, News TV, and a trading platform all in one black screen that costs $24,000/year. Every serious finance professional uses it — it's the one screen to rule them all.
The Bloomberg Terminal provides real-time and historical data on 35+ million financial instruments across equities, fixed income, FX, commodities, and derivatives. Functions run via mnemonics: DES (security description), YAS (yield analysis), ALLQ (all quotes), BVAL (evaluated prices). Bloomberg Data License (BDL) provides bulk data via API/SFTP for downstream integration.
ExamplePortfolio manager types "RELIANCE IN Equity DES <GO>" to get full security details, then "RELIANCE IN Equity ALLQ <GO>" to see all live quotes. Risk system pulls Bloomberg's BVAL prices nightly via Data License for next-day NAV calculation.
Refinitiv / LSEG Data
ELI5Bloomberg's biggest rival. Same idea — a giant financial data universe. Often preferred in fixed income and by banks who also use their trading infrastructure.
Refinitiv Eikon provides data for 450+ exchanges. RICs are the native identifier (e.g., .NSEI for Nifty 50 index). Elektron provides ultra-low-latency real-time feeds for algo trading. DataStream has 50+ years of historical data for macro research. World-Check is the industry-standard database for KYC/AML/sanctions screening — used in payments onboarding.
ExampleA bank's payments system uses Refinitiv World-Check to screen beneficiary names against 1M+ sanctions entries in real-time. Meanwhile, their quant team pulls 30 years of equity return data from DataStream to backtest a factor model.
Markit / S&P Global
ELI5For derivatives and bonds that rarely trade, Markit provides the "official" estimated prices — like a trusted appraiser who everyone agrees to use.
Markit specialises in OTC markets where live prices don't exist. Markit RED is the definitive reference database for CDS — defines what constitutes a credit event, provides RED codes identifying legal entities for CDS contracts. Markit EDM provides enterprise data management for instrument master data. Post-merger with IHS, S&P Global Markit is now the dominant OTC data provider.
ExampleA bank's credit desk trades a 5Y CDS on Tata Motors. They use Markit RED to confirm Tata Motors' exact legal entity, correct RED code, and standard documentation reference. Markit's end-of-day CDS spread marks are used for daily P&L and risk reporting.
ICE Data Services (IDC)
ELI5For bonds that barely trade (like a 20-year corporate bond), ICE provides a "best estimate" of what it's worth today, using smart algorithms. Without this, nobody knows how to price the portfolio.
ICE's evaluated pricing service covers 2.8M+ fixed income instruments. Uses proprietary models combining last trades, comparable bonds, interest rate curves, and credit spreads to generate daily evaluated prices. Critical for fund NAV calculation, regulatory reporting, and risk measurement for illiquid securities. ICE Bonds also operates electronic bond trading venues.
ExampleA mutual fund holds a 15-year municipal bond that last traded 6 months ago. ICE EDM provides a daily evaluated price of $103.25 based on the current yield curve and comparable muni credit spreads — enabling the fund to calculate accurate daily NAV and meet regulatory fair-value pricing requirements.

Trade Execution Systems

OMS — Order Management System

Central hub for managing the entire order lifecycle — from creation to execution to allocation. Key functions: order creation, routing, compliance pre-trade checks, post-trade allocation, position keeping.

Major platforms: Charles River IMS, Aladdin (BlackRock), Simcorp Dimension, SS&C Eze OMS, FlexTrade.

EMS — Execution Management System

Sits alongside the OMS, focused purely on the execution layer — smart order routing, algorithmic execution, real-time market data integration, direct market access (DMA).

Major platforms: Bloomberg EMSX, Fidessa (now ION), Flextrade EMS, LatentZero Capstone, Advent Moxy.

FIX Protocol — Financial Information eXchange

The universal messaging standard for electronic trading communication. FIX messages carry order instructions between buy-side OMS, brokers, and exchanges. Industry standard since 1992.

FIX Tag Examples: Tag 35 (MsgType) = D → New Order Single Tag 35 = 8 → Execution Report Tag 54 = 1 → Buy | 2 → Sell Tag 44 = Price Tag 38 = Order Quantity

DMA — Direct Market Access

Allows buy-side firms to route orders directly to exchange order books without broker intervention. Faster execution, lower costs, full execution control. Requires sponsored access from a prime broker.

Algorithmic Trading Systems

Automated execution strategies to minimise market impact and achieve best execution. Key algos:

  • TWAP — Time Weighted Average Price: slices order evenly over time period
  • VWAP — Volume Weighted Average Price: follows market volume curve
  • POV — Participation rate: executes as % of market volume
  • IS (Implementation Shortfall) — minimises slippage vs decision price

Post-Trade Systems

TMS (Trade Management System): Post-execution — trade confirmation, allocation to sub-accounts, booking to custodians.

IBOR (Investment Book of Record): Real-time position keeping — the definitive source of investment positions.

ABOR (Accounting Book of Record): Accounting-based positions used for NAV and regulatory reporting.

Key Integration Points

  • OMS ↔ Market Data (Bloomberg/Refinitiv) — real-time pricing for compliance checks
  • OMS ↔ Broker via FIX — order routing and execution reports
  • OMS ↔ Custodian — post-trade settlement instructions (SWIFT)
  • OMS ↔ Risk System — pre-trade compliance, post-trade P&L
OMS vs EMS
ELI5OMS is the office manager who tracks all orders from creation to completion. EMS is the Formula 1 driver who actually executes the trade in the fastest, smartest way possible.
OMS: Manages the entire order lifecycle, compliance checks (pre-trade), allocations (post-trade), position keeping, and connectivity to settlement. Single source of truth for all orders. EMS: Laser-focused on best execution — routing to multiple venues, smart order routing (SOR), algorithmic execution, real-time market data. Together they form OEMS (combined platforms increasingly common).
ExamplePortfolio manager creates a 50,000-share HDFC buy order in Charles River OMS. Pre-trade compliance check passes (no restriction, within limit). Order sent to Bloomberg EMSX (EMS). EMSX runs VWAP algorithm, slicing across NSE and BSE throughout the day. Fills report back to OMS for allocation to fund accounts.
FIX Protocol
ELI5FIX is the universal language all trading systems speak to each other. Like English between international businesspeople — it doesn't matter what system you use, FIX makes them all understand each other.
FIX (Financial Information eXchange) is the de-facto standard for electronic trading communication. Tag-value pairs carry all trade information. FIXT 1.1 and FIX 5.0 are current versions. FIX sessions require logon handshake, heartbeat messages, and sequence number management. Mission-critical — any FIX connectivity issue can cause missed executions.
ExampleOMS sends FIX NewOrderSingle (35=D): 54=1 (Buy), 55=RELIANCE (symbol), 38=5000 (qty), 44=2800 (price), 40=2 (limit order). Broker's system sends back ExecutionReport (35=8): 39=2 (filled), 31=2799.50 (fill price), 32=5000 (filled qty). Complete, machine-readable execution record.
Algorithmic Trading
ELI5Instead of dumping 100,000 shares on the market all at once (crashing the price), an algorithm sells them slowly over the day, blending in with normal trading so nobody notices and gets a better average price.
VWAP tracks volume curve — executes more when the market is busy. TWAP slices equally by time. IS (Implementation Shortfall) minimises slippage vs the decision price — balances market impact vs timing risk. POV follows a % of real-time market volume. Choice depends on urgency, order size, and liquidity profile.
ExampleHedge fund needs to sell 2M Infosys shares (3% of ADV — average daily volume). Using a straight market order would crash the price. VWAP algo over 5 days: participates at ~60% of volume during high-volume periods (open, close), lower during midday — achieves close to benchmark VWAP with minimal market impact.
IBOR vs ABOR
ELI5IBOR is the trader's real-time view of positions ("what do I own right now?"). ABOR is the accountant's view ("what do I own according to the books, for NAV calculation?"). They often differ by unsettled trades.
IBOR (Investment Book of Record): Real-time, trade-date positions including trades in-flight. Used for investment decisions, risk management, intra-day exposure. ABOR (Accounting Book of Record): Settlement-date, accounting-basis positions. Used for NAV, regulatory reporting, financial statements. Reconciling IBOR vs ABOR is critical — the gap is pending settlements.
ExampleFund buys 10,000 HDFC Bank shares on Monday. IBOR immediately shows +10,000 position. ABOR shows 0 (not settled yet). On T+1 settlement, ABOR also shows +10,000. The Monday IBOR-ABOR difference = 10,000 shares pending settlement — reconciled daily.

Bonds

What are Bonds?

Bonds are fixed income debt instruments issued by government and corporate entities to raise funds for various projects and activities. When you buy a bond, you're lending money to the Issuer (Borrower).

In return you receive: Coupon Payments (regular interest at predetermined intervals) and repayment of Face Value (principal) at maturity.

Key Terms

Face Value: Value of a financial instrument as stated by the issuer. Fixed value set by issuer.

Market Value: Price determined by supply & demand.

Types of Bonds

Zero-Coupon Bonds: Do not pay interest — only the principal (full face value) at maturity.

Fixed Rate Bonds: Coupon rate is fixed till maturity.

Floating Rate Bonds: Interest rates are adjusted periodically based on a benchmark like SOFR, ESTRON etc.

Inflation Linked Bonds: Adjust their interest and principal payments against inflation.

Yield

Yield is the return an investor earns from a bond; expressed as annual percentage. Unlike the Coupon; yield changes as the bond price changes.

Yield = (Coupon Amount / Market Price) × 100 Example: Coupon rate = 6% | FV = 1000 Annual coupon = 1000 × 6% = $60 Market price = $1050 Current Yield = 60/1050 = ~5.7%

Yield vs Price of Bond: Inversely Related

Bond (Fixed Income)
ELI5You lend your school $100 for 1 year. They pay you $5 every 6 months (interest) and give your $100 back at the end. That's a bond — you're the bank.
Fixed-income debt security. Issuer borrows capital, promises periodic coupon payments and principal repayment at maturity. Rated by credit agencies — AAA (safest) to D (default). Yield and credit rating are inversely related. Government bonds (gilts/G-secs/T-bills) carry sovereign risk; corporate bonds carry corporate credit risk.
ExampleIndia 10Y G-sec: FV ₹1,000, coupon 7.18%, semi-annual payments of ₹35.90, matures 2033. Institutional investors (insurance, pension funds, banks) hold G-secs as a core portfolio component — mandatory under SLR (Statutory Liquidity Ratio) for Indian banks.
Yield vs Price Inverse Relationship
ELI5If bonds go on sale (price drops), they give you a better deal for the same coupon — so the yield goes up. They always move opposite to each other. Always.
When market interest rates rise, existing bonds with lower coupons become less attractive — prices fall, pushing yield up to match new market rates. When rates fall, bond prices rise and yields fall. Duration measures this sensitivity — a bond with 10Y duration loses ~10% in price for every 1% rise in yields.
ExampleYou hold a bond with $60 annual coupon. At FV $1,000: yield = 6%. Rates rise — price falls to $900: yield = 60/900 = 6.67%. Rates fall — price rises to $1,100: yield = 60/1100 = 5.45%. Same coupon, completely different yield based on market price.

Payments

Crucial Details of a Payment

  • Client name
  • Beneficiary
  • Currency (USD / …)
  • Swift Message
  • IBAN

1. Payment Initiation

Client sends payment instruction including: Beneficiary name, address; BK Code; Currency, Amount. KYC ensures the client is a verified/authorised customer. Confirm account is active and is allowed to transact.

2. Validation & Compliance Screening

Checks message format validation. Sanctions Screening: Ensuring neither the client nor the beneficiary is on the Sanctions list. Verify Beneficiary name, bank, account number. Check if payment does not exceed internal approval thresholds.

Payment Validation: Pre-processing

Internal Compliance: AML monitoring — unusual patterns, large sum, high risk counterparties. Validate the Swift Codes, BIC Codes for routing. Cut off time check: Ensure the payment can be processed within bank and clearing systems deadlines.

3. Payment Routing & Messaging

Routing: Confirming the path — direct or via intermediaries.

4. SWIFT / Funding & FX Handling

Client account is debited in EUR. FX Conversion done to EUR → USD. USD is Credited to SocGen. MT103 → beneficiary bank. MT202: Cover payment — Correspondent Bank holding SocGen's account.

Sanctions & AML Screening

Screened: Beneficiary, Beneficiary bank, Intermediary banks.

Cross-Border Payment Flow
ELI5Sending money internationally is like sending a letter through several post offices — your bank hands it to a big correspondent bank, who hands it to the recipient country's bank, who finally delivers it.
International payments flow through correspondent banking networks. Originating bank debits client, converts currency if needed, sends SWIFT MT103/PACS.008 to correspondents that credit beneficiary bank. Each leg involves compliance checks, routing decisions, and liquidity management in Nostro/Vostro accounts.
ExampleYou send €10,000 from BNP Paribas Paris to supplier at HDFC Mumbai: BNP debits EUR account → FX to USD → BNP's USD correspondent (JP Morgan NY) sends to HDFC's USD correspondent → HDFC converts INR → supplier credited. 4 banks, 2 FX conversions, multiple SWIFT messages.
Nostro / Vostro Accounts
ELI5Nostro = "our money sitting in your bank." Vostro = "your money sitting in our bank." Banks maintain these accounts with each other globally to facilitate fast cross-currency payments.
Correspondent banking relationships require banks to hold balances in each other's accounts. Nostro ("ours"): your bank's account held at a foreign bank in foreign currency. Vostro ("yours"): a foreign bank's account held at your bank. These are the actual pools of money that fund international settlements.
ExampleHDFC maintains a USD Nostro account at JP Morgan New York. When HDFC receives a USD SWIFT payment instruction from a client, funds flow from JP Morgan's books (HDFC's Nostro) to the beneficiary's US bank. HDFC's treasury manages the Nostro balance daily to avoid overdrafts.

Beneficiary

What is a Beneficiary?

Beneficiary is an individual/company/entity designated to receive funds/assets from a financial transaction — ensuring money goes to the correct recipient for things like:

  • Investment payouts
  • Dividends
  • Large transfers
Beneficiary
ELI5The person or company at the end of the money pipeline — the one who actually receives the cash when a payment lands.
The designated recipient of funds in a financial transaction. Accurate beneficiary details (name, IBAN, BIC, address) are mission-critical — errors cause PACS.004 returns, delays, potential fraud. Beneficiary verification (Confirmation of Payee / CoP) is increasingly mandated by regulators to prevent authorised push payment (APP) fraud.
ExampleAsset manager sells fund position. Beneficiary = investor's bank account. Operations team ensures correct IBAN, BIC, beneficiary name match on settlement instruction. Single digit IBAN error → automatic PACS.004 return, same-day resolution required to avoid settlement failure.
