Bank Rate rise Thursday expected to lift UK to 4%

London's rates market is priced for a first meaningful tightening step in more than three years. A Bank Rate rise Thursday is expected to move the Bank of England's policy rate from 3.75% to 4.0% when the Monetary Policy Committee publishes its decision at 12:00 GMT.

What happened

BBC News said analysts expect the rise from 3.75% to 4%, describing it as the first hike in more than three years, with the announcement due at 12:00 GMT on Thursday. September CPI was cited at 3.5%, up from 3.1%. A worked tracker-mortgage example in the same piece put the monthly increase near £31 for a 0.25 percentage-point move, while Moneyfacts average two-year and five-year fixed mortgage rates stood at 5.96% and 5.99% as of November 4.

The Bank of England's own monetary-policy summary page for November 2026 still stated ahead of the release that the MPC summary and minutes were "to be published at 12pm" on 5 November 2026, confirming the decision had not yet landed at research time.

Prediction markets were already treating the outcome as near-certain: Polymarket's Bank of England plus-25-basis-point contract was still open with Yes pricing near 98.55% on the morning of decision day, leaving little room for a hold surprise in overnight sterling pricing.

Why it matters

A confirmed move to 4% would re-anchor UK front-end rates just as U.S. political risk is reshaping global duration. Our Bank of England November hike preview already framed the near-98% odds into the meeting; the Bank Rate rise Thursday simply converts that pricing into an official print.

Other English-speaking central banks have already moved. The RBA cash rate hike to 4.85% showed how sticky inflation can still force hikes even late in the cycle; a BoE step to 4% keeps the UK in that same late-cycle tightening club for now.

Mortgage maths will transmit quickly into household cashflow narratives even if markets are fully priced, because average fixed deals near 6% leave little buffer if the MPC signals further tightening in the minutes.

Sterling and short sterling futures already embed the 25-basis-point step, so the market-moving content is the reaction function in the minutes rather than the headline rate. Households fixing mortgages near Moneyfacts averages of 5.96% and 5.99% for two- and five-year deals will feel the tracker example near £31 a month quickly if lenders reprice variable products into the weekend. For gilt traders the comparison with Australia's move to 4.85% is the international context: late-cycle hikes remain live when CPI is still running above target, even if financial conditions elsewhere have started to loosen on political relief.

What's next

Market participants will also weigh liquidity conditions into the U.S. afternoon, because thin books can exaggerate follow-through moves even when the fundamental catalyst is already in the price. Desk commentary after the print emphasized verifying primary-source figures against secondary wraps before treating any single headline number as settled. That verification habit matters when multiple outlets round the same tape differently across time zones.

The 12:00 GMT release and accompanying minutes are the immediate catalysts for gilt and sterling reaction. The Bank's November MPC page is the primary official source once the Bank Rate rise Thursday decision is posted.

Vote splits and any forward guidance on whether 4% is a way-station will matter more than the widely expected 25-basis-point step itself.

UK inflation prints after September's 3.5% CPI will decide whether markets keep pricing another hike or treat Thursday as the peak for this cycle.
