Bank of England chief economist pushes for a hike ahead of the 17 September MPC vote
Bank of England chief economist Huw Pill has called for an immediate bank rate rise. He warned that waiting for Middle East uncertainty to resolve before acting risks letting inflation pressures become entrenched.
Pill made the case in a speech at the Edinburgh Chamber of Commerce, telling the Monetary Policy Committee (MPC) it could not afford to delay. He was one of only three members to vote for a bank rate rise at July’s meeting. The majority, including governor Andrew Bailey, held benchmark rates at 3.75%.
Pill argued a 25-basis point increase to 4% would send, in his words, a “clear and unambiguous signal” of the MPC’s resolve on upside inflation risks. He also warned that holding steady risked embedding a “bias to the status quo”, allowing Iran-linked energy costs to push inflation higher for longer.
What does a bank rate rise mean for UK mortgage rates?
Fixed costs have already climbed sharply since the Iran conflict began in late February 2026.
Bank of England data published in July 2026 showed the typical two-year fixed rate at 75% loan-to-value (LTV) had risen to 4.92%, up from 4.20% in December 2025. At 90% LTV – common among first-time buyers – the average climbed from 4.57% to 5.32%.
Swap rates are the primary driver. When wholesale funding costs rise, lenders reprice fixed-rate products. Markets are now pricing at least one base rate rise before year-end.
The Moneyfacts Average New Mortgage Rate climbed to 5.59% at the start of August 2026, reversing all gains made in June. Two- and five-year fixes averaged 5.63% and 5.66% respectively – the first monthly rise since April 2026, per the Moneyfacts UK Mortgage Trends Treasury Report.
Average product shelf-life fell to 11 days — the shortest since April 2026 — as lenders withdrew and repriced deals in response to swap movements. The full breakdown of how lenders have repriced across product ranges sets out the scale of that shift.
How are UK mortgage brokers navigating the bank rate uncertainty?
For brokers advising clients on whether to fix, track or wait, September adds to an already difficult conversation.
Tracker borrowers face direct exposure to any upward move in the base rate.
Those on standard variable rates – averaging 7.13% as of August 2026, according to Moneyfacts – have limited buffer remaining. A 25-basis point rise adds roughly £13 per month per £100,000 borrowed, based on Moneyfacts repayment modelling.
Around 1.8 million fixed-rate mortgages are due to expire in 2026, per UK Finance. Many of those borrowers locked in sub-3% deals in 2020 and 2021. They are now rolling off into a markedly different environment. Earlier analysis of Pill’s rate arguments and their implications for UK lending gives useful context for those client conversations.
Pill acknowledged that one move need not signal the start of a sustained tightening cycle. A prompt rise could instead anchor expectations early, heading off what he called insidious catch-up inflationary dynamics.
That argument will resonate with brokers worried about prolonged swap rate volatility affecting affordability calculations.
Bailey has kept a more cautious tone. He said the Bank’s position was reasonable given the unpredictability of events in the Middle East.
He has also separately warned G20 finance ministers that a collapse in the artificial intelligence sector could trigger a wider global market correction. The Bank is monitoring this risk alongside the energy shock.
