ING strategists say sterling rates remain highly sensitive to UK inflation risks, with markets reacting more to the inflation outlook and Bank of England policy than to sovereign risk. They point to oil prices having moved well above $100 as a period when markets rapidly priced a tightening cycle, and contrast that response with the ECB. With inflation still not back at target, the path to 2% is seen as vulnerable to any inflation-inducing shock.<\/p>\n\n
They add that fiscal expansion is priced differently when inflation is rising than in a disinflationary backdrop, making the timing of spending plans central for the rates curve. Markets are pricing a terminal Bank of England rate around 4%, which sits above the current bank rate of 3.75%, and ING expects this to change next year as conditions become more disinflationary. Near-term initiatives, including debated defence spending, are therefore associated with more upward pressure on GBP rates than commitments scheduled further out.<\/p>\n\n
We see that Sterling markets remain highly sensitive to UK inflation risks, particularly around any new fiscal spending plans. With UK inflation data showing a persistent 2.8%, still well above the Bank of England’s 2% target, traders are nervous about any policy that could add to price pressures. This makes the front-end of the rates curve, which reflects near-term interest rate expectations, very jumpy.<\/p>\n\n
From our perspective, the biggest threat is that near-term spending could once again delay the return to target inflation. Any immediate fiscal stimulus would likely force the market to price out the potential for a Bank of England rate cut later this year, which is currently a baseline expectation. Spending promised for several years down the line, however, should have a much smaller impact on current trading.<\/p>\n\n
This environment suggests that buying short-term sterling volatility is a prudent strategy for the coming weeks. We believe derivative positions that benefit from sharp moves in interest rate expectations, such as short-dated swaptions or straddles on SONIA futures, are positioned to perform well. These instruments are directly tied to the “jumpiness” we expect around any major government spending announcements.<\/p>\n\n
We also see an opportunity in trades that bet on a flattening of the UK yield curve. A curve flattener, which profits when short-term rates rise faster than long-term rates, seems appropriate given the market\u2019s focus on immediate inflation threats. This reflects the historical pattern seen during the 2022-2023 inflationary period, where the front-end of the curve reacted far more aggressively to policy and inflation news than the long end.<\/p>\n\n\n\n
