France, Germany and the UK issued a joint statement on 1 March condemning Iran’s “indiscriminate and disproportionate” missile attacks. The leaders warned they are prepared to support necessary and proportionate defensive action to disable launch capabilities at source, and said they will work with the US and regional partners.

For markets, that single line about enabling action “at source” matters because it raises the probability of further military steps if barrages continue. It pushed geopolitical risk premia across energy, shipping and FX back to the fore before European cash trading on Monday, with investors focusing on supply security and insurance availability.

Oil moved first. In early trade, Brent briefly spiked above $82 a barrel before easing towards the high‑$70s, while WTI jumped toward the low‑$70s. The intraday pattern suggests a risk premium rather than confirmed production outages-at least for now-after weekend strikes and counterstrikes. (energynow.com)

The chokepoint is clear. Roughly one‑fifth of global crude transits the Strait of Hormuz, and early indications pointed to slower tanker movements alongside reports of insurers restricting cover, which raises the hurdle rate for any voyage. That combination explains why crude rallied even before hard evidence of lasting supply loss emerged. (apnews.com)

Marine war‑risk costs were already elevated through 2025 and into 2026. Marsh data cited by CNBC showed premiums rising from about 0.125% to 0.25%–0.45% of hull value, with episodes spiking near 0.5%, while some underwriters stepped back from ships with US, UK or Israel links. Any renewed cancellations would feed directly into freight rates and delivered energy costs. (cnbc.com)

Scenario work now frames the upside tails. BloombergNEF estimates that a full, sustained disruption to Iranian exports could push Brent averages toward $90 later in 2026, while other analysts warn that a prolonged blockage of Hormuz could force spot prices into three digits. These are not base cases-but they are back on traders’ whiteboards. (about.bnef.com)

Equities reflected the shift in tone where markets were open. Indian defence names jumped as much as 13% on Monday, a familiar pattern from previous flare‑ups when European primes such as BAE Systems, Rheinmetall, Thales and Leonardo also attracted flows amid budget and order optimism. Valuations were already rich after last year’s rally. (m.economictimes.com)

FX traded to the playbook. The Swiss franc and Japanese yen firmed as safe‑haven demand picked up, the euro softened, and gold caught a bid-signalling classic de‑risking. Early pricing showed the dollar a touch stronger versus sterling, underscoring that energy‑importer currencies tend to underperform when oil spikes. (investing.com)

For UK corporates and CFOs, the near‑term calculus is straightforward. Upstream energy benefits from firmer crude, but airlines, logistics and any importer exposed to Gulf shipping lanes face higher fuel and potential war‑risk surcharges. If premiums persist near the 0.3%–0.5% of hull value range seen in past spikes, cash‑flow planning for Q2 needs a rethink. (cnbc.com)

Policy risk remains the swing factor. The E3’s coordination with Washington and regional partners-and their readiness to enable defensive action-will guide whether this is a short, sharp repricing or the start of a longer risk cycle. The stance builds on the E3’s tougher line through 2025, including activation of UN “snapback” measures over Iran’s nuclear non‑compliance. (gov.uk)
