What was a fringe view in February has become the central debate at the Bank of England. Three of nine Monetary Policy Committee members are now expected to formally vote for a rise of at least 25 basis points at the May meeting, according to two people briefed on the committee's preliminary discussions. That would be the largest hawkish block since the post-Covid tightening cycle ended in 2024.
The hawkish trio, understood to include Catherine Mann and Megan Greene, were already pushing back against the consensus at the March meeting. What has changed since is the data. Services inflation printed at 5.4 per cent in the latest release from the Office for National Statistics, against an MPC central forecast of 4.8. Wage growth in the private sector, the Bank's preferred labour-market indicator, accelerated to 5.7 per cent on a three-month annualised basis.
The committee's central case has not moved, but the tail risks have, and three members are now pricing those tails differently from the rest.

For markets, the immediate question is whether the dissent gets formalised in the May minutes or surfaces only in speeches afterward. Sterling has already begun to price the difference. The implied probability of a 25 basis point hike by the August meeting moved from 18 per cent on Friday to 31 per cent at Monday's close, according to OIS-implied curves at major UK banks.
Why the dissent matters now
A 3-6 split is not a hike. It is, however, a change in the texture of UK monetary policy that has been absent for two years. The committee has spent that period either cutting or holding, with dissent running at most one or two members in either direction.
A larger dissent block has two consequences. First, it shifts the burden of the central case. Andrew Bailey, the governor, has been able to talk to a fairly settled centre throughout the easing cycle. He cannot do that with three members openly diverging from the framing. Second, it raises the volatility of guidance. When dissent is two members, market participants treat the published statement as the policy. When it is three, they begin to treat the speeches as policy and the statement as compromise text. That is a different information environment for traders, treasurers, and corporate hedgers.
The Treasury, meanwhile, has its own reasons to watch closely. The latest Office for Budget Responsibility scenario analysis assumes a flat path for Bank Rate through year-end. A material upward revision would tighten fiscal headroom in the autumn statement. The OBR has not yet revised its assumption.
What it means for the FTSE 250
Domestic-focused UK equities, which spent the easing cycle under-owned by international funds, are the most exposed to a hawkish surprise. The FTSE 250's correlation with two-year gilt yields is the strongest of any major European index, according to research published by Goldman Sachs (NYSE: GS) earlier this month. A 25 basis point upward revision to the rate path historically maps to a 3 to 4 per cent index move on the day of the announcement.
Operators with floating-rate debt are watching, too. Helical (LSE: HLCL) and other UK property names disclosed in their most recent updates that they have hedged the bulk of their 2026 maturities, but a faster path materially raises the cost of any 2027 refinancing.
None of this is a forecast about whether the hike happens. The May minutes will tell that story. What is already true is that the May meeting is no longer a procedural hold. It is, for the first time since 2024, a contested decision.
