Trade-Date and Settlement-Date Accounting for Bond Amortization
Summary
The document compares trade-date and settlement-date treatment for bond amortization and accretion. One answer cites performance standards that call for trade-date accounting and accrued-income accounting for fixed-income securities. Another distinguishes posting a trade to positions on the trade date from recognizing bond income and calculating amortization: it argues that these begin on settlement date, when the bond’s discounted purchase price is measured relative to future cash flows.
The settlement-date explanation says amortization or accretion runs through maturity, or through applicable call or put dates, with schedule legs reflecting the pricing basis. For a sale, it says the calculation runs through but excludes the settlement date. The responses therefore describe different timing conventions and scopes, including performance reporting versus income and premium or discount calculations. The document does not reconcile the interpretations or establish a universal accounting rule; the applicable standard, jurisdiction, and accounting purpose need to be checked before applying either view.
Key ideas
- Trade-date accounting records trades in positions as of the trade date under the cited performance standard.
- The responses distinguish performance accounting from the timing of bond income and amortization.
- One answer places income recognition and premium amortization or discount accretion from settlement date.
- Amortization schedules may end at maturity or relevant call or put dates.
- The document presents differing interpretations and does not resolve which convention applies universally.

# Does amortization of bond start accumulating on trade date or settlement date? # Does amortization of bond start accumulating on trade date or settlement date? I am sorry if this is not appropriate here. We are building a wealth management system and I really would like to know whether amortization of bond start accumulating on trade date or settlement date according to common accounting standard. Thanks! ## Answer by Ram Ahluwalia (score 2) https://quant.stackexchange.com/a/4126 Global Investment Performance Standards state that bond amortization performance evaluation starts on trade date rather than settlement date. On the attached see 1.A.5 which states: > 1.A.5 For periods beginning on or after 1 January 2005, FIRMS MUST use TRADE DATE ACCOUNTING. 1.A.6 ACCRUAL ACCOUNTING MUST be used for fixed-income securities and all other investments that earn interest income. The value of fixed-income securities MUST include accrued income. ## Answer by Roger Gregory (score 0) https://quant.stackexchange.com/a/42341 Trade date accounting means posting trades to positions on trade date, valuing positions inclusive of that day's trades, and posting corporate action entitlements as of ex-dividend date on positions that include trades through and inclusive of the previous business day. I am in full agreement. Fixed income securities trade with accrued interest calculated through settlement date. Recognition of income for bonds starts on settlement date with the first day's income included in the valuation as of the close of business on settlement date. Bond-pricing discounts future cash flows to settlement date. The bond price from which market premium is amortized or market discount is accreted is the discounted price on settlement date, therefore amortization and accretion should begin being calculated on settlement date. The amortization/accretion schedule should terminate on maturity date, unless there are one or more call or put dates. The amortization schedule dates should be based on how the bond was priced (best, worst, next), which may result in multiple legs, with each leg terminating at that day's call or put price. When a bond is sold, amortization and accretion are calculated through but exclusive of the settlement date.
