Interest rate risk

Floating-rate borrowers face higher cash interest when reference rates rise, while depositors may receive less when rates fall. Fixed-rate instruments have different exposure: their market values generally change when required yields change, even when contractual cash payments do not. Analyse the amount, timing, currency, benchmark and reset terms before selecting a response. Matching, fixed-rate finance, FRAs, swaps, futures and options can manage particular exposures but leave costs and other risks. A hedge appropriate for a future deposit can have the opposite direction from one for future borrowing.

Worked example

A business will borrow $2 million at a floating annual rate for six months. A rise of 1 percentage point increases simple interest by $2m × 0.01 × 6/12 = $10,000, before any hedge, tax or fees.

Common mistake

Assuming fixed-rate debt has no interest-related risk at all, or hedging a deposit in the same direction as borrowing.
