On 13 June 2025, Israel launched airstrikes against Iranian nuclear and military sites, and Iran responded with missile and drone attacks over the following hours. The escalation put global markets on edge and revived long-standing concerns about oil supply routes through the Middle East. This article reviews what happened on the day and how crude, safe-haven assets and broader risk sentiment responded.

What Happened

Financial markets, coming off a relatively quiet start to June, were unprepared for the scale of the operation. Before dawn on 13 June 2025, Israel struck Iranian nuclear facilities and military sites, killing several senior commanders. Iran declared a state of emergency and prepared to retaliate, later launching missile and drone strikes on Israeli targets. The United States said it was not involved in the initial operation, while urging Tehran not to target American personnel or interests in the region. The sudden escalation pulled market attention away from trade negotiations and toward the risk of a wider regional conflict, one capable of threatening energy flows across the Middle East and lifting inflation expectations.

Oil Prices and the Supply Risk

Crude posted its sharpest one-day move since Russia's 2022 invasion of Ukraine. US crude (WTI) settled about 7.3% higher near $72.98 a barrel, its highest level since early April, while Brent rose roughly 7% to settle near $74.23. Intraday gains were larger before prices pared back. The core concern was the concentration of supply: roughly a fifth of the world's oil passes through the Strait of Hormuz, and Iran exports close to 1.6 million barrels a day. Several analysts stressed that supply would be materially affected only if the conflict escalated to strikes on regional oil infrastructure.

Safe Havens and Risk Assets

Demand for protection was immediate. Gold rose about 1.4% to roughly $3,433 an ounce, a near two-month high, as the dollar also drew safe-haven flows against several major peers. Equities weakened across regions: the S&P 500 fell 1.13% to 5,976.97, the Nasdaq Composite lost 1.30% to close at 19,406.83, and the Dow Jones dropped 769.83 points, or 1.79%, to 42,197.79. Defense names moved the other way, with RTX gaining 3.3%, Northrop Grumman rising nearly 4%, L3Harris Technologies climbing just over 3%, and Lockheed Martin adding over 3%, as investors positioned for a prolonged regional conflict.

What It Means for Traders

Geopolitical shocks tend to move quickly and reprice several markets at once. Oil, gold, the dollar and equity indices all reacted within hours, and much of the initial oil risk premium faded later as traders judged an actual supply disruption unlikely. Episodes like this illustrate why position sizing, clearly defined risk and awareness of headline-driven volatility matter. Prices can gap on overnight or weekend developments, spreads can widen, and intraday ranges can expand sharply. Recognising which instruments carry a geopolitical risk premium, and how quickly that premium can unwind, supports a more disciplined reading of these phases. Defense and energy-linked equities, alongside havens such as gold, are typically among the instruments most likely to see outsized moves in the opening hours of a Middle East escalation.
