Bank of England Holds Rates as Energy Shock Tests Disinflation

A unanimous vote to keep Bank Rate at 3.75% signals a deliberate pause, as Middle East conflict drives oil above $100 and threatens to stall Britain’s return to price stability.

Key Takeaways

• The MPC’s shift from a 5-4 split in February to a unanimous hold in March reflects a meaningful recalibration toward caution, not a change in the direction of travel on rates, as the committee preserves optionality ahead of what could be a prolonged energy shock.
• Brent crude above $100 a barrel and UK natural gas futures up 35-40% represent a supply-side disruption the Bank cannot directly address; its task is to prevent the price adjustment from feeding into wage and price-setting behaviour in ways that re-anchor inflation above target.
• With the next Monetary Policy Report due in May and the following meeting on 30 April, the near-term path of UK rates depends critically on how quickly Middle East tensions and energy markets evolve, keeping mortgage costs elevated and corporate investment decisions in a holding pattern.

The Vote That Changed Its Meaning

Six weeks ago, the Bank of England’s Monetary Policy Committee voted 5-4 to hold Bank Rate at 3.75%, a margin thin enough to suggest the next move could go either way. On 19 March, the same committee voted nine to nothing for an identical outcome. The number was the same; the message was different.

Unanimity in monetary policy rarely reflects simple agreement. It reflects a shared assessment that the balance of risks has shifted sufficiently to make the alternative untenable. What changed between February and March was not domestic data, which had continued to improve modestly, but the eruption of a geopolitical shock severe enough to remind policymakers that disinflation is a condition, not a destination.

Conflict involving Israel, the United States and Iran has targeted energy infrastructure across the Middle East, effectively closing the Strait of Hormuz to commercial shipping. The strait carries roughly one-fifth of global oil and liquefied natural gas. The immediate market consequence was a surge in Brent crude to above $100 a barrel, some 60% above the Bank’s February forecast baseline, accompanied by UK natural gas futures rising between 35% and 40%. Dutch TTF prices moved similarly. The energy complex, which had been one of the more cooperative components of the disinflation process, reversed course sharply.

Domestic Progress, Interrupted

The domestic backdrop heading into this disruption had been, on balance, encouraging. CPI inflation fell to 3.0% in January from 3.4% in December, tracking the Bank’s own forecasts closely. Services inflation, long the stickiest element of the price basket, eased to 4.4%. Private-sector wage growth of 3.3% in the three months to January came in below expectations, and pay settlements for 2026 were being projected at 3.6%, a figure consistent with a cooling rather than reigniting labour market.

Activity, meanwhile, remained subdued without being alarming. GDP expanded by just 0.1% in the final quarter of 2025, with January’s monthly output flat. Unemployment held at 5.2%, vacancies stayed below equilibrium, and broad money growth of 3.6% suggested no excess liquidity building beneath the surface. The economy was not gathering pace, but it was moving in the right direction: generating enough slack to keep inflation expectations anchored while avoiding the kind of weakness that would force an emergency cut.

Into this measured progress arrived what the MPC itself described as a supply shock reminiscent of 2022, though one starting from a lower base and landing in a more slack economy. The comparison is instructive. In 2022, the energy shock arrived when demand was running hot and labour markets were exceptionally tight. This time, the output gap is wider and the labour market more balanced. That distinction matters for how aggressively second-round effects might propagate, and it informs why the MPC chose restraint rather than pre-emptive tightening.

What the Bank Can and Cannot Do

The committee was explicit on this point: monetary policy cannot move global commodity prices. What it can do, and what the decision on 19 March was designed to do, is ensure that the unavoidable adjustment in real incomes and spending does not trigger a second wave of domestically generated inflation. The danger is familiar. Higher energy bills squeeze household budgets, firms face rising input costs in transport, manufacturing and retail, and workers seek compensatory wage increases. If those increases are granted and embedded in multi-year settlements, the inflation problem mutates from a supply-side event into a structural one. That is the channel the Bank is watching most carefully.

Governor Andrew Bailey was measured in his public commentary, describing the hold as appropriate while the committee gathered evidence on the shock’s scale, duration and propagation. Deputy Governor Sarah Breeden framed the objective as ensuring economic adjustment occurs in a way that achieves the 2% target sustainably. Catherine Mann noted that sustained energy pressure could tilt the balance toward a longer hold, or even a rate increase. Megan Greene pointed to staff estimates showing CPI remaining above 3% for much of the year. Across the minutes, the tone is one of watchful restraint, a posture that acknowledges the risk without pre-committing to a response.

Markets React to Delay, Not Direction

The decision arrived fully priced. In the days before the announcement, implied probabilities of a hold reached 97% or higher. The FTSE 100 fell approximately 1.9% to close around 10,110 on 19 March, erasing much of the prior session’s gains. Consumer, insurance and mining stocks weighed on the index; energy shares provided only partial offset. The FTSE 250, more exposed to domestic conditions, performed similarly.

The reaction was telling. A hold that might previously have been read as broadly supportive of risk assets now registered as a delay to easing. Two-year gilt yields had already risen sharply in preceding weeks as traders stripped out near-term cut expectations. Sterling traded below $1.37 against the dollar. These moves represent a de facto tightening in financial conditions that the rate decision itself did not directly cause but did nothing to reverse.

The Road to May

The easing cycle that began in August 2024 brought Bank Rate from a peak of 5.25% down to its current level over the course of roughly eighteen months. The pace was deliberate and the logic was clear: as inflation fell and economic slack widened, the case for restrictive policy gradually diminished. The next full Monetary Policy Report, due in May alongside the subsequent rate decision, will set out revised forecasts incorporating the energy shock and any further data on its persistence.

For now, the committee has preserved its options. A conflict resolution that allows energy prices to recede would likely restore the conditions for further easing later in the year. A protracted disruption would require a reassessment of the rate path in both direction and timing. Mortgage costs, already elevated, are unlikely to ease materially in the near term. Savers retain relatively attractive returns on cash. Corporate investment, already cautious in a low-growth environment, faces further uncertainty over input costs.

Discipline in a Volatile World

The Bank of England’s March decision is, in one sense, simply a hold. In another, it is a statement of institutional character: that the authority to set interest rates carries with it an obligation not to overreact to shocks the policy instrument cannot directly address, while remaining alert to the secondary effects it very much can influence. The disinflation achieved since 2023 was hard won and is not, as this week demonstrated, permanently secured against external disruption.

What the MPC has shown is that it understands the difference between the two problems. Whether the energy shock proves a temporary interruption or a more durable challenge to the 2% anchor remains the central question of the next several months. The committee has bought itself time to find out.
