The US has struck Iran for the second time in three days, hitting a military site near the Strait of Hormuz that it says threatened US forces and commercial shipping, and shooting down multiple Iranian drones. Iran’s Revolutionary Guard says it hit back at a US air base and has warned of a more decisive response. In the same window, Kuwait activated its air defenses against hostile missile and drone threats. The market read is clean: risk sentiment has been hit, oil is pushing higher on Strait of Hormuz supply fear, the dollar is catching the safe-haven bid, and gold, counter-intuitively, is being sold. Here is the whole story and what it means for the tape.

The facts, cross-referenced

What happened: the second strike in three days

The US military carried out fresh strikes on Iran overnight into Thursday, targeting a military site that officials said posed a threat to US forces and to commercial maritime traffic in the Strait of Hormuz. Alongside the strike, US forces intercepted and shot down multiple Iranian drones in the same area. CNBC reported the US shot down four Iranian attack drones and hit a ground control station at Bandar Abbas that was preparing to launch a fifth.

This is the second military exchange in a matter of days, and the most significant since the ceasefire between Washington and Tehran took effect last month. The war itself began on 28 February 2026 with US and Israeli attacks on Iran. It has run for roughly three months, killed thousands, and sent global energy prices sharply higher. The ceasefire was supposed to draw a line under it. The strikes this week are the clearest sign yet that the line is not holding.

The timing matters. It comes after a stretch where the market had been pricing the war premium out: President Trump had signalled an imminent deal to reopen the Strait of Hormuz, and Iranian state television said Tehran was committed to restoring commercial shipping through the strait to pre-war levels within a month. Oil had fallen hard on that. Then the strikes landed, and the de-escalation trade went into reverse.

Iran’s response and the Kuwait flashpoint

Iran’s Islamic Revolutionary Guard Corps said it launched an attack on a US air base that it claims was the source of the strikes, and warned that any further US attacks would bring a more decisive response, with Washington bearing responsibility for the consequences. That is the escalation ladder talking, not the de-escalation track.

Around the same time, Kuwait’s army said its air defenses were responding to hostile missile and drone threats, and that any explosions heard were those threats being intercepted. Kuwait did not say where the attacks came from. The significance is the contagion risk: this is no longer just US-versus-Iran across a single border. The Gulf states that host US assets are back in the firing line, and that is exactly the kind of widening the oil market fears most, because it threatens the chokepoint the whole region’s crude flows through.

What it means for the markets

Risk sentiment has been hit, and the cross-asset move is textbook for a war-risk re-escalation that the market had stopped pricing. The premium that had been bled out over the past fortnight is being put back on in real time. Three things are happening at once: oil is pushing higher on Hormuz supply fear, the dollar is catching the safe-haven bid, and gold, against the reflex of most retail traders, is being sold. Take them in turn.

Oil: the Strait of Hormuz is the whole story

Brent jumped more than 3% on the strike. To understand why, you have to understand the strait. Roughly a fifth of the world’s seaborne oil passes through the Strait of Hormuz, a narrow channel between Iran and Oman. When the US strikes military sites in that exact area and Iran threatens a more decisive response, the market does not wait for a tanker to actually be hit. It prices the probability of disruption, and that probability just jumped.

The move is sharper because of where oil was sitting. Crude had fallen around 16% across May, with Brent dropping below 95 dollars on Wednesday after Iran pledged to restore Hormuz shipping to pre-war levels. The strikes did not just add a premium to a calm market, they slammed the de-escalation trade into reverse. The desk’s full playbook for trading this is here: how to trade oil (WTI and Brent).

The dollar: where the safe-haven bid is going

The dollar is the haven winning the flow this cycle. The dollar index is building a higher structure and working into the heavy area of liquidity around 99.50, the gap it left behind when it sold off on the original ceasefire. Gaps with resting liquidity act as magnets, and the war headline is the catalyst pulling price back into the zone. The desk’s full read, with the levels and the trade, is here: DXY penetrates the 99.50 liquidity. For the bigger picture on why US-Iran is the single biggest driver of the dollar right now, read the dollar outlook for June 2026.

The mirror of a bid dollar is pressure on the majors. EUR/USD is breaking down, with 1.1590 the line and 1.1520 the next liquidity below: the full EUR/USD read is here. GBP/USD is breaking down too, with 1.3380 support and 1.3300 in play, and a softer UK backdrop on top: the full cable read is here.

Gold: why it is being sold on a war headline

This is the part most retail traders get wrong today. The reflex is that war means buy gold. But gold is being sold, and there are three reasons stacked on top of each other. First, the dollar is winning the safe-haven flow, and a rising dollar mechanically pressures dollar-priced gold. Second, higher oil feeds inflation fears, which keep interest rates higher for longer, and higher rates raise the opportunity cost of holding a metal that pays you nothing. Third, gold flushed a key technical level this morning: the 4,500 liquidity got taken out, momentum flushed to the downside, and stops were triggered to the south.

The desk’s read is that while price holds below 4,500, the order block at 4,400 down to 4,300 is the next test, and a break there draws price toward 4,100 and then 4,000. The full level-by-level breakdown, and what would flip it back bullish, is here: gold (XAU/USD) 4,500 liquidity flushed.

Today’s desk levels across the board

Here is where the desk has the four instruments it traded this morning, each with the full analysis linked. These are headline-driven levels, so size accordingly and use hard news-stops both ways.

What the desk is watching next

• A confirmed tanker incident in the Strait of Hormuz. That is the real escalation trigger for oil, and the headline that could flip gold back to a genuine haven bid that overrides the dollar.
• Whether Iran’s more decisive response threat actually materialises, and whether any further Gulf-state US asset is hit after Kuwait.
• A de-escalation headline: a restored ceasefire, a halt to strikes, or a formal commitment to reopen the strait. Any of those fades the whole move, the dollar drops back below 99.50, and gold rebuilds.
• The 17 June Fed meeting. The market still leans toward a hold, which keeps the dollar’s rate-differential leg intact, but a dovish surprise would cut the leg from under it.
