US strikes Iran for 9th night as Rubio keeps door open to diplomacy

The US military completed its ninth consecutive night of strikes against Iran on Sunday, even as Secretary of State Marco Rubio said the administration "remains open to diplomatic solutions," a dual-track approach that has pushed Brent crude above $85 a barrel and gold to a three-month high above $2,450 an ounce.

"The strikes will continue degrading Iranian military capabilities used to attack commercial vessels and civilian mariners transiting the Strait of Hormuz," US Central Command said in a statement announcing the latest wave of attacks, which began at 7 p.m. ET Sunday. The ninth round of strikes came hours after CENTCOM reported finding the remains of a missing US service member struck by the same missiles that killed two troops Friday night, bringing the total American death toll to 17 soldiers since the start of the conflict.

The Strait of Hormuz handles about 21% of global oil trade, making any sustained disruption a direct threat to crude supply chains. WTI crude has gained roughly 12% since the first strikes were launched nine days ago, while the CBOE Volatility Index has climbed above 22, reflecting heightened uncertainty across equity markets. Defense sector stocks have outperformed the broader S&P 500 by about 8 percentage points over the same period, according to market data.

Rubio's statement late Sunday that the US remains open to diplomacy introduces a potential off-ramp, but the lack of a specific framework or timeline leaves the trajectory unclear. The last time the US engaged in sustained strikes against Iran without a parallel diplomatic track was during the 2019-2020 tanker war in the Persian Gulf, when crude prices spiked 15% over six weeks before stabilizing after a ceasefire. The current escalation has already matched that duration of sustained strikes, with no ceasefire mechanism announced.

Fox News contributor Joey Jones noted that the targeting strategy blurs the line between military and civilian infrastructure. "They'll say things like, 'We hit 160 telecom towers that could be used for drones,' so they are connecting the civilian infrastructure to the military operations, which the IRGC essentially operates in Iran to begin with," he said. The Islamic Revolutionary Guard Corps controls large portions of Iran's economy, making targeted strikes that avoid civilian infrastructure technically difficult.

For markets, the key variable is whether the diplomatic signal from Rubio translates into concrete negotiations or remains a rhetorical gesture. If the administration pursues talks, crude could give back some of its recent gains, with Brent likely settling in the $78-$82 range. If strikes continue without a diplomatic track, the risk premium could push oil above $90, while gold and the dollar would continue to attract safe-haven flows. The next data point for traders will be whether the US launches a tenth round of strikes, which would signal that the military track remains the primary strategy.
