The main market shift has been the rise of interest rates, which has caused Banks to struggle in maintaining their current structural hedges whilst managing their liquidity positions. To protect Net interest Margin (‘NiM’), Banks normally use either on-market or in some cases, off-market interest rate swaps (‘IRSs’) to economically hedge interest rate risks (‘economic hedges’). The use of IRSs will result in profit and loss (‘P&L’) volatility if hedge accounting (or other forms of offsetting fair value treatment) is not applied.
The recent increased volatility in interest rate movements and increased cost of capital have resulted in increased use of economic hedges. A classic example is UK Government gilts which are generally at fixed rates and where Banks have traditionally classified at fair value through other comprehensive income (‘FVOCI’) for liquidity purposes. The low interest rate environment prior to 2022 meant that hedges using IRSs to economically hedge against interest rate mismatch between floating rate borrowing and the fixed rate gilts, were not considered and also hedge accounting was therefore not applied.
However, as interest rates rose, the fair value of the gilts effectively fell impacting the Bank’s reserves and the gap between interest income and expense also widen because the fixed rate received on the gilts that were purchased prior to 2022, would be lower than the current borrowing floating interest rates. Such events have caused Banks to find optimal ways to protect their NiM and reserves such as using off-market IRSs. Such economic hedging activities will most likely result in increased P&L volatility that is generally mitigated by applying hedge accounting.
