Fixed income operations demand precision at every stage. A miscalculated accrual on a single bond position can cascade into incorrect NAV figures, compliance mismatches, and settlement failures that take days to unpick. For investment managers running large fixed income portfolios, the ability to configure bond pricing, interest accruals, and settlement workflows correctly within a single platform is a foundational operational requirement.
SimCorp One addresses this through an integrated fixed income module that handles these three critical functions within the same data environment that governs compliance, performance, and risk. Getting the configuration right from the outset determines how reliably the platform performs under real portfolio conditions.
The Operational Importance of Accurate Bond Pricing
Bond pricing is not simply a matter of pulling a market quote. The accurate valuation of a fixed income security requires applying the correct yield curve, day count convention, settlement date assumption, and accrued interest calculation to produce a clean price and a full dirty price that together determine the economic value of the position. For SimCorp bond pricing software to function correctly, each of these inputs must be configured consistently across all instrument types in the portfolio.
SimCorp One is widely recognised as a leading investment management platform with extensive fixed income capabilities. That integration is what makes SimCorp’s fixed income module operationally superior to environments where pricing, accruals, and settlement are managed in separate systems.
Configuring Bond Pricing in SimCorp
Bond pricing configuration in SimCorp starts with the instrument master, where each fixed income security is assigned its pricing methodology, yield curve input, and settlement convention. The platform supports multiple pricing sources, including third-party evaluated pricing services, exchange feeds, and broker-supplied prices, with a configurable source hierarchy that determines which price takes precedence for each instrument type under different market conditions.
The bond amortisation calculation functionality within SimCorp handles both straight-line and effective interest method amortisation of bond premiums and discounts, with the system selecting the correct treatment based on the accounting standard applicable to each fund. For US-domiciled funds operating under US GAAP and Canadian funds following IFRS, the amortisation treatment differs, and SimCorp’s accounting engine applies the correct methodology to each fund without requiring separate system configurations for each jurisdiction.
Interest Accrual Configuration Across Instrument Types
Day Count Convention Setup
Day count conventions determine how accrued interest accumulates between coupon dates and directly affect the accrued interest calculation that appears in settlement amounts and NAV production. SimCorp supports all major day count conventions, including Actual/Actual, Actual/360, Actual/365, 30/360, and 30E/360, configurable at the instrument level. For a portfolio containing a mix of US Treasuries, UK Gilts, European corporate bonds, and Canadian government bonds, the day count configuration must be set correctly for each instrument type to produce accurate accrual figures across the portfolio.
Coupon Frequency and Accrual Period Management
Fixed income instruments accrue interest on different schedules. Annual coupon bonds, semi-annual payers, quarterly floaters, and zero-coupon bonds all require different accrual calculation logic. SimCorp handles each of these through instrument-level configuration that defines the coupon frequency, the first and last coupon dates, and any irregular coupon period adjustments for short or long first periods. The platform’s defaulted fixed income securities module also provides specific treatment for bonds that have entered default, reversing outstanding coupon accruals, redemption payments, and amortisation entries systematically rather than requiring manual adjustment.
Floating Rate Note Configuration
Floating rate notes present additional complexity because their coupon rate resets at each fixing date. SimCorp’s accrual engine handles FRN coupon resets by connecting the instrument’s fixing schedule to the relevant market interest rate index, applying the new rate automatically from the reset date. For SOFR-linked instruments replacing LIBOR-based products in US and Canadian portfolios, the fixing methodology configuration must correctly reference the new benchmark and apply any credit spread adjustment required under the fallback provisions of the relevant ISDA protocol.
Inflation-Linked Bond Accruals
Inflation-linked bonds accrue interest on a principal balance that adjusts with the relevant inflation index. SimCorp handles index-linked principal accretion as part of the framework for bond accrual calculation, updating the inflation index reference daily and calculating coupon accruals on the adjusted principal amount. For Canadian Real Return Bonds and US Treasury Inflation-Protected Securities (TIPS), the index lag convention differs, and SimCorp’s instrument setup accommodates both without requiring separate processing modules.
Accruals for Distressed and Non-Standard Securities
Not all fixed income securities follow standard coupon structures. Payment-in-kind bonds, step-up coupons, and toggle notes all require specific accrual treatment. SimCorp’s flexible instrument master supports non-standard cash flow structures through configurable coupon schedules that can replicate the economic terms of these instruments without custom development. This flexibility is particularly important for portfolios that include private credit or high-yield instruments with bespoke documentation.
Income Accrual for Settlement Purposes
Accrued income must be calculated correctly at the point of settlement, because the buyer of a bond pays the clean price plus accrued interest to compensate the seller for holding the bond between coupon dates. SimCorp’s settlement workflow captures the accrued interest figure from the instrument’s accrual calculation and incorporates it into the settlement amount automatically, ensuring that the settlement figure presented to custodians and counterparties is accurate without manual calculation by operations teams.

Corporate Bond Settlement Configuration
The corporate bond settlement workflow in SimCorp operates from the moment a trade is captured through to final settlement confirmation from the custodian. Settlement instruction generation is automated based on the pre-configured SSI for each counterparty and settlement system, with SimCorp supporting T+1, T+2, and T+3 settlement cycles depending on the market and instrument type. The US shift to T+1 settlement in May 2024 and Canada’s corresponding alignment require that settlement workflows produce accurate instructions on trade date without reliance on overnight batch processing cycles.
Settlement exceptions, including failed trades, partial deliveries, and corporate action adjustments that affect settlement quantities, are managed through SimCorp’s exception workflow. The platform flags settlement breaks automatically and routes them to the appropriate operations team for resolution, maintaining a complete audit trail from trade entry to settlement completion. This auditability is particularly important for US SEC-registered investment advisers and Canadian investment managers subject to CIRO supervision, both of whom face documented expectations around settlement workflow governance.
