The Strait of Hormuz is expected to remain closed through the summer, with continued risks stemming from naval mines, potential terrorist attacks on vessels, and high insurance costs, even if hostilities with Iran come to a swift end. This disruption threatens global energy supplies, with particular implications for the United Kingdom and other developed economies.

Energy prices are anticipated to stay elevated throughout 2026 and likely into 2027, exerting upward pressure on inflation rates well above the central banks’ 2 percent targets. The impact extends beyond direct fuel costs, affecting sectors such as agriculture, where fertilizer production depends heavily on natural gas.

In response to persistent inflation, interest rates are projected to rise over the coming months. In the UK, financial markets have priced in two potential increases from the Bank of England this year, with the first expected in June. However, the Bank’s Monetary Policy Committee is unlikely to act immediately given current uncertainties, although officials remain cautious not to repeat previous delays in addressing inflationary pressures. Across the Atlantic, the direction of the U.S. Federal Reserve remains somewhat unclear pending the appointment of its new chairman, Kevin Warsh, but his recent testimony indicates he intends to take necessary measures to control inflation. Similarly, the European Central Bank is expected to maintain a hawkish stance.

Long-term bond markets already reflect inflation concerns, driving up government borrowing costs. The yield on UK ten-year gilts approached 5 percent recently, compared with 4.3 percent on similar U.S. Treasury notes and over 3 percent on German Bunds—figures representing some of the highest levels in over a decade. This increase signals heightened caution among investors, particularly regarding the UK’s economic vulnerability.

While disruptions to oil and gas supplies will be felt, some analysts caution against framing the current situation as the severest energy crisis since the 1970s. The UK, as a net exporter of petrol, is somewhat insulated despite reliance on imports of crude oil and refined products such as jet fuel and diesel, with about half of the jet fuel currently sourced from the United States. Nonetheless, supply constraints are likely to prompt cancellations of flights across Europe, which could have knock-on effects on related industries.

Consumer behavior reflects adaptive responses to the evolving energy landscape. Recent retail data from the UK show increased spending, driven in large part by consumers filling fuel tanks ahead of expected price rises. Such preemptive actions, along with greater saving rates globally, indicate that households are adjusting to higher costs and economic uncertainty.

Despite a predicted slowdown across Continental Europe and East Asia, the UK's service-focused economy is comparatively less exposed to external shocks. However, the cumulative impact of elevated energy costs layered on domestic policy challenges means economic conditions are expected to remain difficult.

An open question remains as to whether financial markets fully appreciate these economic pressures. While UK equity prices have retreated from recent highs, they remain above levels seen at the start of the year. U.S. markets continue to hover near record peaks. A Bank of England official recently noted that current share valuations may not fully reflect the challenges ahead. Yet market sentiment appears to suggest confidence in the global economy’s resilience, a view that some analysts share.
