The Bank of England is running out of reasons to wait. On September 17, the Monetary Policy Committee voted 6-3 to hold Bank Rate at 3.75%, with three members — Catherine Mann, Megan Greene, and chief economist Huw Pill — already voting for an immediate quarter-point increase. But what changed the calculus was what happened next: Governor Andrew Bailey and his deputies Sarah Breeden, Clare Lombardelli, and Dave Ramsden all signaled they could back a rate rise, shifting the balance of the committee decisively toward tightening.

Three weeks later, markets are pricing an 86% chance of a hike at the MPC’s November meeting, according to LSEG data. UK gilt yields have surged to multidecade highs in anticipation, and sterling has started to rebound. The Bank of England, long the cautious outlier, is about to become the last major central bank to join the 2026 tightening cycle.

The September hold — and why November looks different

The September decision was closer than the headline suggests. Inflation stood at 3.1% in August, up from 2.9% in July — well above the 2% target — and the Bank now expects it to reach slightly above 4% in early 2027, more than double its previous 3.2% peak forecast. Bailey and his deputies, who voted to hold, nonetheless hardened their language, arguing that given the lags with which second-round effects appear, it was not appropriate to wait too long for evidence of such effects before responding with policy.

Since then, the hawkish drumbeat has only grown louder:

• Huw Pill, the Bank’s chief economist, said central banks must keep working to control inflation and drew little comfort from the rise in bond yields.
• Megan Greene warned that UK wage growth could reach around 3.5% in 2027, sustaining inflationary pressure and increasing the need for rate hikes.
• Catherine Mann argued that real financial conditions are insufficiently tight and backed a clearly communicated, restrictive path for Bank Rate.
• Andrew Bailey reiterated monetary policy’s unwavering commitment to returning inflation to target.

Bond markets have taken the hint. On October 8, ten-year gilt yields climbed to 5.527% — their highest since 2007 — and thirty-year yields reached 6.047%, the highest since 1998, per LSEG data. Sterling, meanwhile, rebounded from near three-month lows to around $1.324 on October 9 as oil prices eased after US President Donald Trump ruled out an attack on Iran before the November midterm elections.

Macrometer’s 2026 global tightening scoreboard

The Bank of England’s reluctance stands out in a year of coordinated tightening. Here is where the world’s major central banks sit after the September round of decisions — compiled by Macrometer from central bank announcements and market surveys:

The tally is striking: of the six major central banks tracked, five have tightened in 2026. The Bank of England alone has not moved — making it, as market commentators have noted, the only major central bank yet to begin tightening in response to inflation pressures stemming from the US-Iran war. The common thread across all of them is energy: crude above $100 a barrel has pushed headline inflation up everywhere, with eurozone inflation at 3.8% in September — nearly double the ECB’s target.

The case for a November hike

The hawks’ argument rests on three pillars. First, inflation is moving the wrong way. At 3.1% and rising, with a 4%-plus peak now projected, the UK’s overshoot is among the worst in the developed world — and it has exceeded the 2% target in all but three months over the past five years.

Second, markets are already doing some of the tightening, but not enough. Some MPC members pointed to higher gilt yields as a reason to wait, but Mann dismissed that logic: if real financial conditions are insufficiently tight, bond-market tightening alone will not finish the job.

Third, expectations matter. IMF research published on October 6, drawing on data from 76 countries over three decades, found that cost-of-living crises raise inflation expectations for years after food and energy prices surge — complicating central banks’ efforts to bring inflation down. For a central bank staring at energy-driven price rises, acting early to anchor expectations is textbook policy. BNP Paribas economist Dani Stoilova calls the likely November move an insurance hike.

The case for waiting

The doves have a rebuttal. Higher yields are already tightening financial conditions without the Bank lifting a finger: thirty-year gilt yields at their highest since 1998 and mortgage costs at multi-decade highs will slow demand on their own. The MPC itself noted in September that signs of persistent pressure were not yet showing up in wage demands or business pricing.

There is also the fiscal backdrop. The late-October budget will set the tone for public spending and debt issuance, and investors have already added a fiscal-risk premium to gilts amid weak growth. Hiking into a fragile fiscal picture risks compounding the pain — the UK’s Q3 growth estimate of 0.4% remains modest even after the September upgrade.

Finally, energy is the swing factor. Brent retreated after Trump’s remarks on Iran, and if the ceasefire talks hold, some of the inflation pressure could fade without a hike. Goldman Sachs has argued softer data could keep rates on hold in November — though it, like Barclays, still expects a hike.

What to watch next

The November decision will hinge on a packed calendar: the IMF’s full World Economic Outlook lands October 13; the Fed decides October 27-28; the ECB meets October 29 with markets leaning toward holding before a December move; and the UK budget arrives in late October. The next UK inflation print, and whether wage negotiations at the turn of the year start baking in 4% inflation — the risk Mann flagged — will be decisive.

If the Bank does move in November, it will close the last gap in the 2026 tightening cycle. Every major central bank will then be raising rates into an energy-shocked economy — a synchronized tightening not seen in years, and a test of how much restraint growth can take before something breaks.
