The Iran war has created the most acute policy tension for the Bank of England since Brexit, with the committee voting unanimously to hold rates at 3.75% on Thursday as it navigates the competing pressures of external inflation risk and domestic economic weakness in a way that has no easy resolution. The monetary policy committee described the conflict as a significant new shock that had introduced a degree of policy complexity not seen since the uncertainties of the Brexit period, when the Bank similarly faced competing arguments for tightening and easing simultaneously. Officials warned that inflation could rise above 3% and that rate hikes might be needed.
The Brexit parallel is instructive in several ways. Like the current situation, Brexit created a combination of external-origin price pressures — through the depreciation of the pound and its impact on import costs — and domestic economic uncertainty that argued for caution rather than decisive action in either direction. The Bank’s response then was similarly to hold and monitor while retaining options, a strategy that proved effective in managing a period of genuine uncertainty.
Governor Andrew Bailey said the Bank was applying similar principles of careful observation and conditional readiness in the current situation. He warned of the energy price risks from the conflict and said the Bank was prepared to act if inflation became entrenched, while resisting pressure to commit to a specific path before the evidence justified it. His Brexit-era playbook of watchful patience has been dusted off for the Iran war episode.
Financial markets were less patient than the Bank, pricing in rate hikes in June and later in the year. UK gilt yields rose, the FTSE 100 fell, and the pound strengthened against the dollar as traders made their bets on the outcome of the acute policy tension. Analysts noted that the resolution of the tension would depend primarily on the war’s duration and energy market impact, factors entirely outside the Bank’s control.
For UK economic policy overall, the most acute tension since Brexit creates a period of institutional pressure that tests the quality of decision-making under uncertainty. The Bank’s handling of that pressure — calm, evidence-based, and transparent about the limits of its knowledge — is an important public good in itself, providing a degree of institutional stability in an unstable environment.
