BoE Holds Rates: The Flow of Inflation Risk

The Bank of England's Monetary Policy Committee delivered a decisive shift on March 18, voting unanimously to maintain the Bank Rate at 3.75%. This 9-0 decision marks a stark reversal from just weeks prior, when markets assigned a 65% probability to a rate cut. The primary driver is a significant increase in global energy and commodity prices due to the Middle East conflict, which directly pressures household and business costs.

The immediate market reaction confirms the new reality. Consensus has now tightened to a 97.6% probability of no change, a dramatic reversal that reflects the MPC's warning of increased inflationary risks. The conflict has caused a sharp rise in energy prices and volatility, with shipping through the Strait of Hormuz almost halting. This shock is expected to push CPI inflation higher in the near term, forcing the MPC to prioritize containing second-round effects in wages and prices.

The bottom line is that the risk flow has changed. The MPC is now alert to the danger that longer higher energy prices will embed inflationary expectations. While the central bank cannot control global oil prices, its policy stance is now dictated by the need to ensure the economic adjustment to this shock achieves the 2% target sustainably.

The Inflationary Pressure Test

The new risk is translating into concrete price pressures. The MPC's minutes detail a sharp rise in both the level and volatility of energy prices, with Brent crude spot prices over $100 per barrel and European gas prices surging around 60% from pre-conflict levels. These are not abstract shocks; they directly feed through to household fuel and utility bills, which the committee explicitly notes will be affected. The immediate inflation impact is clear: CPI inflation is expected to be higher in the near term as this shock works its way through the economy.

The MPC's primary concern is the potential for these costs to trigger second-round effects. The committee is alert to the increased risk of domestic inflationary pressures through second-round effects in wage and price-setting. The longer higher energy prices persist, the greater this risk becomes. This is the critical test: whether businesses pass on higher input costs to consumers, and whether workers demand higher wages to offset increased living costs, creating a self-reinforcing cycle that could derail the disinflation trend.

Financial markets are pricing in this elevated risk. The minutes note that distributions implied by financial market options also suggested that upside risks to oil and gas prices had increased significantly, at least over the next few months. This market sentiment aligns with the MPC's warning, indicating that the path for energy prices is now skewed to the upside. The central bank must now navigate the dual pressure of containing this inflationary shock while also assessing the weakening in economic activity that higher energy costs will inevitably cause.

The Path Forward: Guidance and Catalysts

The Bank of England is now on a wait-and-see footing, with its next decision scheduled for 30 April 2026. Governor Andrew Bailey's post-meeting comments emphasized monitoring developments extremely closely, a stance that has already shifted market expectations. The central bank's guidance will be the critical signal; any shift from its current description of the policy rate as being in "restrictive territory" to a more hawkish framing could instantly signal a pivot from hold to hike.

The key catalyst for that pivot is the persistence of higher energy prices and their impact on wage growth. The MPC is explicitly warning of increased risk from second-round effects, where higher fuel and utility bills translate into greater wage pressures. If evidence from the next Monetary Policy Report shows this transmission accelerating, the case for a rate rise above the current 3.75% level would strengthen significantly. The risk is that energy prices, which have surged due to the Middle East conflict, become entrenched.

Market forecasts now reflect this heightened uncertainty, with predictions for 2026 ranging from a cut to 4.25%. The divergence is stark: some models suggest rates could climb to 4.5% if energy cost shocks last a year, while others still see a cut in April or June. The bottom line is that the hold is a pause, not a commitment. The path forward hinges entirely on whether inflationary pressures prove transitory or become embedded, with the next data and the BoE's own language serving as the primary catalysts.
