The Iran war’s economic impact on the UK is demanding a coordinated policy response from the Bank of England and the government, with the central bank voting unanimously to hold rates at 3.75% on Thursday and warning that monetary policy alone cannot fully address the inflationary consequences of a geopolitical supply shock. Governor Andrew Bailey’s explicit call for the restoration of energy supply lines as the most effective solution to the inflation threat acknowledged the need for policy tools beyond the Bank’s remit to complement its monetary response. Officials warned that inflation could rise above 3% and that rate hikes might be needed.
The case for coordination rests on the complementary nature of the policy tools available. The Bank of England can influence demand through interest rates, dampening the inflationary consequences of the energy shock by reducing consumer spending and business investment. The government can provide targeted fiscal support to households most affected by rising energy costs, maintaining living standards without adding to inflationary pressure. International diplomacy can work toward restoring the energy supply chains whose disruption is the root cause of the problem.
Governor Bailey stopped short of explicitly calling for government action, reflecting the Bank’s independence. However, his repeated references to the household impact of rising energy costs and his acknowledgement of the limits of monetary policy implicitly identified the space that government fiscal action could usefully fill. The Bank’s communication was designed to be informative about the full range of policy options, not just the one it directly controls.
Financial markets focused on the monetary dimension of the response, 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. Analysts noted that the effectiveness of the overall policy response would depend on both the Bank’s rate decisions and the government’s support measures.
For the UK economy as a whole, the coordination challenge is significant. The Bank and the Treasury are separate institutions with different mandates, but the effectiveness of each depends in part on what the other does. If the government provides adequate energy support, the Bank may not need to raise rates as much to keep inflation in check. If the Bank raises rates aggressively, the government may need to provide more fiscal support to maintain household finances. Getting the coordination right will be a key determinant of how well the UK navigates the Iran war’s economic consequences.
