Inflation is falling, but not fast enough for the mortgage market
CPI inflation fell to 2.8% in April 2026, down from 3.3% in March. The reduction was primarily driven by the energy price cap coming down — a mechanical move rather than a broad softening in underlying price pressures. Services inflation, which is what the Bank of England watches most closely, remains elevated.
The Bank of England held base rate at 3.75% at its 29 April 2026 meeting, with an 8-1 vote among Monetary Policy Committee members. The single dissenter voted to raise rates. That lone hawk is significant: it signals that the committee is not uniformly dovish, and that any further softening in the labour market or another inflation surprise could shift the balance. Markets have largely priced in one further cut in 2026, but the timing is uncertain.
Why mortgage rates are rising despite falling inflation
The disconnect between CPI figures and mortgage rates is one of the most confusing aspects of the current market. The explanation lies in gilt yields. UK ten-year gilt yields have risen by around 0.6 percentage points since the start of 2026. Lenders price their fixed-rate mortgages off swap rates, which track gilts closely. When gilt yields rise, swap rates rise, and mortgage pricing follows — regardless of what the Bank of England does with base rate or what CPI prints.
The average two-year fixed rate rose from 4.83% on 1 March 2026 to 5.75% on 18 May 2026. That is a move of nearly one full percentage point in under three months. For a contractor on a £400,000 mortgage, that translates to roughly £200–£240 per month in additional interest cost.
The drivers of elevated gilt yields include global energy price volatility, Middle East tensions that continue to add a risk premium to energy markets, and political uncertainty around UK government borrowing intentions. These are not factors that will resolve quickly.
What this means for contractors on expiring fixes
Contractors who fixed two or three years ago will have locked in at rates substantially below what is currently available. A two-year fix taken in May 2024 might have been at 4.5% or below. Rolling onto a new deal now means accepting something in the 5.5–5.75% range unless a competitive product is identified. The payment shock is real.
The case for acting promptly is strong. Swap rates are the key variable to watch: they can move in either direction. Waiting for rates to fall while your current fix expires means spending time on a standard variable rate (SVR), which is typically 7–8%. The SVR exposure period alone will often cost more than any saving from waiting for a marginally better fixed rate.
Lower inflation helps over a medium-term horizon. If CPI continues to fall and the Bank of England does cut rates later in 2026, swap rates should eventually follow. But mortgage pricing leads macro moves, and there is no guarantee of the timing. Certainty now is more valuable than the prospect of saving 0.1% in six months' time while sitting on an SVR.
