Iran War Shocks Global Economy, BoE Warns
1 Apr
Summary
- Iran war significantly increases global economic instability.
- Millions of UK borrowers face higher mortgage payments soon.
- War drives inflation, tightens financing, and impacts markets.

The Bank of England has issued a stark warning that the Iran war threatens global financial stability, delivering a substantial shock to the world economy. This conflict exacerbates existing risks in financial markets, including private credit. The central bank projects that approximately 5.2 million UK borrowers, or three in five households, will experience increased mortgage payments by the end of 2028.
The war has already caused significant market movements, with rising oil prices leading to surging government yields and widening credit spreads. The Bank of England anticipates that the conflict will suppress economic growth, fuel inflation, and lead to tighter financing conditions. This heightened uncertainty makes it more difficult for markets to price economic fundamentals, increasing the likelihood of sharp market shifts.
Furthermore, the Bank of England noted that US tech giants' valuations appear stretched, a concern potentially amplified by the war's impact on energy-intensive supply chains. In the UK, while businesses show resilience, SMEs and highly leveraged corporates are particularly vulnerable to supply shocks. The outlook for global bond markets has also worsened, potentially impacting growth and interest rates.
