The escalating tensions between the US and Israel on one side and Iran on the other have sent ripples through global financial markets, with the Bank of England predicting a potential impact on UK households' mortgage payments. This conflict, which has already caused a 'substantial negative supply shock' to the world economy, could lead to an increase in monthly mortgage payments for an additional 1.3 million UK households by the end of 2028.
The financial markets' reaction to the Middle East conflict has been swift and significant. Banks have withdrawn numerous mortgage products, and interest rates on remaining home loans have risen sharply. This phenomenon, dubbed 'Trumpflation,' has put immense pressure on households preparing to take on new mortgage contracts.
The Impact on Borrowers
The average two-year fixed residential mortgage rate has jumped to 5.84%, a significant increase from the 4.83% recorded at the start of March. This rise in borrowing costs has been felt almost immediately, as personal finance analysts report.
The Bank's Financial Policy Committee (FPC) warns that a prolonged war could result in 'large, frequent, and potentially overlapping shocks' that threaten global financial stability. This is particularly concerning given the already elevated global risks and the potential for these shocks to amplify existing vulnerabilities.
Broader Economic Implications
The UK's economic outlook has deteriorated due to the conflict, increasing pressure on households and businesses. The FPC highlights the risk of amplifying pre-existing issues, such as government debt market pressures, exceptionally high AI company valuations, and risky loans from private credit firms operating outside the regulated banking system.
The conflict has made the global environment more unpredictable, and the FPC urges lenders, investors, and financial firms to assess their weaknesses and prepare for potential shocks. This includes incorporating scenarios of sudden price adjustments into their stress testing and liquidity preparedness.
Sovereign Bonds and Debt Markets
The committee also notes the impact on sovereign bonds, including UK gilts, which are used to raise government funds on international markets. Weaker growth prospects, higher interest rates, and increased spending pressures could limit governments' ability to respond to future shocks and worsen vulnerabilities in the debt market.
The trend of international hedge funds holding significant government debt positions adds to these concerns, increasing the risk of a disorderly unwind of positions and a jump to illiquidity in core markets.
Conclusion
The potential consequences of the US-Israel war on Iran are far-reaching and complex. While the financial system has shown resilience so far, the conflict has heightened global risks and increased the possibility of multiple, simultaneous shocks. These shocks could have a significant impact on financial stability and the provision of financial services to UK households and businesses. As an analyst, I believe it is crucial to monitor these developments closely and consider the broader implications for the global economy and financial markets.
