Pulse Analysis

The recent attack on a nuclear facility in the United Arab Emirates reignited concerns about supply disruptions in the oil market, sending Brent crude to $111.16 per barrel—the highest level in almost two weeks. Coupled with stalled cease‑fire negotiations between the United States and Iran, the episode has sharpened inflation expectations as higher energy costs feed into consumer prices. Traders are now pricing in a greater probability of central banks tightening monetary policy sooner than previously projected, a dynamic that could reverberate across all asset classes.

Bond markets mirrored the heightened risk appetite, with the benchmark US 10‑year Treasury yield climbing to 4.63%, its loftiest point since early 2025, before easing back to 4.60%. In the United Kingdom, the 10‑year gilt surged to 5.19% amid speculation that Prime Minister Keir Starmer could face a leadership challenge from Andy Burnham, raising fears of expanded fiscal spending. Analysts warn that any shift toward a more expansionary budget would strain the UK's already tight fiscal space, potentially prompting the Bank of England to adopt a more aggressive rate‑hike trajectory to anchor inflation expectations.

Across the broader market, the G7 finance ministers gathered in Paris to coordinate responses to the Middle‑East turmoil, while Japan’s 10‑year yield touched an almost 30‑year high of 2.8% as the government prepared new debt issuance to cushion the regional shock. European equities slipped, and Asian markets showed mixed reactions, underscoring the global reach of the conflict. Investors will be watching for any de‑escalation signals and for domestic political developments in the UK, both of which could stabilize yields and temper the upward pressure on inflation.
