A fair value hedge is a hedge of exposure to changes in the fair value of a recognised asset or liability, or of an unrecognised firm commitment, that come from a particular risk and could affect profit or loss. The classic case is a company that has issued a fixed interest rate bond and uses a swap to turn it into floating-rate debt. Banks, insurers and corporate treasuries use fair value hedges mainly for interest rate and currency risk.
It is one of the categories of hedge accounting under IFRS 9 and ASC 815. It mirrors the cash flow hedge: a fixed-rate instrument has fixed cash flows but a changing value, while a floating-rate instrument has a stable value but changing cash flows. Choosing which to hedge decides which model applies. Like any hedge relationship, a fair value hedge must be documented and pass a hedge effectiveness assessment.
Fair value hedge in plain terms
Suppose you own a house you plan to sell next year, and you worry that local prices might fall. If you could make a side bet that pays you whenever house prices drop, a fall in your house's value would be matched by the winnings on the bet. Your total wealth stays roughly where it was.
A fair value hedge works that way for things like bonds and loans, whose prices move when interest rates change. The company holds a contract that gains when the asset or debt loses value, and vice versa. The accounting rule then lets the company show both movements in profit together, so readers see the gain and loss netting off instead of a single scary swing.
How the accounting works
The hedging instrument is measured at fair value with changes recognised in profit or loss, which is the normal treatment for a derivative. The special step is on the other side: the carrying amount of the hedged item is adjusted for the change in its fair value attributable to the hedged risk, and that adjustment also goes to profit or loss. Without hedge accounting, a fixed-rate bond issued by the company would stay at amortized cost while the swap was marked to market, creating volatility that does not reflect the economics.
When the hedge ends, the cumulative adjustment to the hedged item is amortized to profit over its remaining life (for interest-bearing items). Under IFRS 9 there is one exception to the profit-or-loss rule: if the hedged item is an equity investment that the company has elected to measure at fair value through OCI, the gains and losses on both sides stay in OCI.
Worked example
A company issues a five-year bond of 100 million at a fixed 5% coupon. It enters a receive-fixed, pay-floating interest rate swap on the same notional and dates, paying SOFR plus a spread, and designates the swap as a fair value hedge of the bond's benchmark interest rate risk.
Over the year benchmark rates fall. The fair value of the bond attributable to that change rises by 3.0 million, meaning the company's liability is now worth more. The swap's fair value rises by 2.9 million. The entries are:
- The bond's carrying amount is increased by 3.0 million, with a 3.0 million loss in profit or loss.
- The swap is recognised as an asset of 2.9 million, with a 2.9 million gain in profit or loss.
- The net effect on profit is a loss of 0.1 million, the hedge ineffectiveness, which might come from the floating leg's spread or from changes in the swap's credit valuation.
The offset of 2.9 ÷ 3.0, about 97%, would pass both the IFRS 9 and the ASC 815 assessments.
Typical uses
- Fixed-rate debt issued. Companies that issue fixed-rate corporate bonds but prefer floating-rate funding swap them, often at the time of issue.
- Fixed-rate assets held. Banks hedge fixed-rate loans or holdings of government bonds against rising rates, managing interest rate risk in the banking book.
- Firm commitments. A signed contract to buy equipment for a fixed amount of foreign currency can be hedged for currency or commodity price risk before it is recognised on the balance sheet.
Portfolio hedging
Banks hedge interest rate risk on large pools of similar loans or deposits rather than one item at a time. IAS 39 includes rules for a portfolio fair value hedge of interest rate risk, and IFRS 9 lets entities keep applying them while the IASB works on a dynamic risk management model. The European Union endorsed IAS 39 with a "carve-out" that relaxes some of these portfolio rules, which many EU banks use. In the US, ASU 2022-01 replaced the earlier "last-of-layer" method with a broader portfolio layer method for closed pools of prepayable assets. These approaches let banks reflect how they actually manage the balance sheet, but they are complex and depend heavily on prepayment assumptions and mark-to-market models whose inputs often sit in Level 2 of the fair value hierarchy.
