UK gilt markets declined as oil and gas prices surged from the Iran conflict, disrupting shipping routes and raising inflation fears across Europe and North America. The energy shock threatens to delay interest rate cuts in major economies, with the Bank of England expected to maintain higher rates longer than markets anticipated.
"The conflict in Iran has pushed up oil and gas prices and disrupted shipping routes," said David Aikman. "Persistent disruption will raise household bills and business costs in the months ahead, putting renewed upward pressure on inflation and potentially interest rates."
Chancellor Rachel Reeves faces a challenging economic backdrop ahead of the spring statement: inflation has eased and borrowing costs have fallen, but unemployment has risen and growth forecasts have weakened. She is expected to deliver a low-key statement, restricting major policy changes to the autumn budget as the UK manages high debt levels while navigating external shocks.
"With debt still unsustainably high, the priority for the chancellor should be to build a credible medium-term plan to put the public finances on a more resilient path, with debt falling as a share of the economy over time," Aikman said.
In the US, fiscal sustainability concerns escalated as the Social Security Board of Trustees warned that retired workers could see payouts cut by 23% in 2033 if Congress fails to address the program's insolvency. The warning has intensified debates over alternative funding mechanisms, including tariff revenue proposals.
California's controversial wealth tax measures added to US fiscal uncertainty, with critics arguing the policy could drive high-net-worth individuals to other states and erode the tax base.
The convergence of geopolitical energy shocks and structural fiscal deficits is forcing major economies to reassess public finance strategies. UK policymakers must balance immediate inflation risks from oil volatility against long-term debt reduction, while US officials confront entitlement program sustainability amid political gridlock.
Bond markets are pricing in extended fiscal uncertainty as governments navigate between crisis response and structural reform, with investors demanding higher risk premiums for long-term sovereign debt.
