The Bank of England Is About to Raise Rates. What Gilts and Sterling Say About What Comes Next.

The Bank of England’s decision Thursday is not really in doubt. Interest rates are widely expected to rise to 4% from 3.75% when the MPC announces at midday London time, which would be the first time the central bank has raised borrowing costs since August 2023. Before the most recent inflation data, 54 of 63 economists surveyed in a Reuters poll already expected a November rise to 4%. The hike is priced. The question worth asking today is what it means for what follows.

The energy shock is driving the urgency. UK headline inflation is expected to rise to around 4% in early 2027 as higher energy prices feed through to household bills. Motor fuel inflation reached 29.8% in September, up from 23.0% in August. But this is not purely an energy story. The details make it difficult for the Bank to dismiss the increase as a temporary shock: core inflation rose to 2.8% from 2.6%, while services inflation accelerated to 3.7% from 3.4%.

The MPC’s internal arithmetic tells the same story. The Committee voted 6-3 to hold at 3.75% at its September meeting, with Andrew Bailey and five colleagues choosing to wait while Megan Greene, Catherine Mann, and Huw Pill voted for a 0.25-point rise to 4%. Bank staff have said inflation is on course to climb to slightly above 4% in the first quarter of 2027, partly linked to another increase in the household energy price cap in January. Two more members need to cross over. The energy data since September has made that crossing easier to justify.

What the Budget Left Behind

Chancellor John Healey’s Budget last week gave the gilt market the one thing it demanded: restraint. Gilts outperformed U.S. Treasuries by about five basis points immediately after Healey’s statement on October 28. The budget kept about £15 billion of fiscal headroom, which eased worries in the bond market. The 10-year yield held around 5.3%, the FTSE 100 and FTSE 250 were up about 0.2%, and sterling was flat at about $1.33.

That calm is real, but it is conditional. As Ebury put it, sterling and gilts have taken it in their stride, “but with only a thin buffer, both remain exposed to weaker growth or a further rise in global borrowing costs.” The 10-year gilt has been trading around multi-year highs for weeks. Yields have held around 5.4%, near multi-year highs, as investors assess stronger-than-expected inflation and rising public borrowing ahead of this week’s MPC meeting. A hike on Thursday is already embedded in that number. What is not yet priced cleanly is how many more follow.

Three Banks, One Week

The broader context matters here. The Fed, the ECB, and the Bank of Japan all held rates steady this past week, but the BoE is moving while they pause. Recent reporting has suggested the Fed could still hike again by the end of 2026 if inflation stays stubborn, and Fed officials have continued to emphasize that additional tightening remains possible. The BoE hiking alone into this environment actually offers sterling some support: rate differentials are moving in the pound’s favor relative to the euro, even if the dollar remains firm.

The risk lies further out. MUFG expects the Bank of England to hike again in February to a 4.25% peak, saying rising energy costs will push UK inflation above 4% while firm growth, a steadier labour market, and sticky underlying prices limit patience. Oxford Economics now expects the Bank to hike by 25 basis points in both November and February, taking Bank Rate to 4.25%. If that path materializes, the fiscal cushion Healey preserved in the Budget shrinks further as debt-servicing costs rise.

Where It Shows Up

For equities, higher rates and energy costs weigh on domestically focused UK stocks, while the FTSE 100’s energy-heavy constituents offer some offset. UK banks sit in the middle: LLOY and HSBA benefit from wider net interest margins as rates rise, but face mounting pressure on mortgage arrears and credit quality if the rate path extends into 2027. Watch the vote count Thursday as much as the decision itself. The vote split is published simultaneously with the decision, and it is often as market-moving as the rate call: a 5-4 vote for a hike is a very different signal than a 7-2 or 8-1.

What to Watch

The November Monetary Policy Report will update the Bank’s inflation forecasts, and any revision toward a higher or later peak will shift rate expectations for December and February. The Bank of England has said it expects UK inflation to lift to “slightly above 4%” in the first quarter of 2027, partly linked to another increase in the household energy price cap in January. If the new MPR moves that peak higher, the hawks gain ground. If the OBR’s growth cuts feed into the Bank’s own models and soften the inflation path, the February hike priced by Oxford Economics and MUFG becomes less certain. That is the real binary Thursday sets up, not the 25 basis points itself.
