U.S.-Iran ceasefire collapse sends investors to 3 defensive ETFs

President Trump declared the U.S.-Iran ceasefire "over" Tuesday as American forces launched fresh strikes against Iranian assets, sending the VIX above 28 and driving capital into defensive exchange-traded funds.

"The breakdown of talks removes the one stabilizing factor that had kept a lid on the risk premium in Middle East assets," said Elena Fischer, geopolitical risk analyst at Edgen. "Investors are now pricing in a prolonged period of uncertainty that will benefit gold and energy while pressuring risk-on equities."

U.S. Central Command said the strikes were retaliation for Iranian attacks on three commercial vessels in the Strait of Hormuz, a waterway that handles about 21% of global oil consumption. Iran responded by targeting Bahrain and Kuwait, according to state media. Trump revoked a license that had allowed Iran to sell oil under the ceasefire framework hours before the strikes, the White House confirmed.

The collapse resets the risk calculus for Middle East exposure at a time when NATO members have committed to spending 5% of GDP on defense by 2035, a shift that has already drawn institutional investors back into the defense sector after years of ethical exclusions. The question now is whether the conflict widens to disrupt oil flows — Brent crude rose 3.2% Tuesday to $84.70 a barrel — or remains contained to tit-for-tat strikes.

Gold and Defense ETFs Draw Inflows

The SPDR Gold Shares ETF (GLD) saw net inflows of $1.8 billion in the two sessions through Tuesday, the largest two-day inflow since March 2024, as investors sought a hedge against currency and geopolitical risk. The iShares U.S. Aerospace & Defense ETF (ITA) gained 2.7% Tuesday, extending its year-to-date advance to 14%, as the breakdown of talks reinforced the case for higher defense spending across NATO.

The Energy Select Sector SPDR Fund (XLE) rose 1.8%, tracking Brent crude's jump. The Strait of Hormuz chokepoint — through which Iraq, Kuwait, Saudi Arabia, and the UAE ship the bulk of their crude — has been a recurring source of supply risk premiums since Iran seized two tankers in April 2025.

Defense Sector Sees Structural Shift

The geopolitical escalation comes as institutional investors are reassessing long-standing exclusions on defense. The Church Commissioners for England removed its 10% revenue cap on defense exposure earlier this year, replacing it with a case-by-case framework that excludes only controversial weapons and oppressive regimes. Danish pension fund AkademikerPension lifted restrictions on six European arms manufacturers in 2025.

"The coming decade will be defined by nations scrambling to secure access to the metals and minerals that power modern economies and defense capabilities," said Douglas Macgregor, a former U.S. Army colonel and senior advisor to the Secretary of Defense, in a statement Tuesday. Palisades Goldcorp, a Canadian resource investment company, appointed Macgregor to its board the same day, citing the need for geopolitical expertise in commodity investing.

What Comes Next

Trump, speaking at the NATO summit in Turkey, said he does not want to deal with Iran anymore, calling them "scum," but did not rule out future talks. NATO Secretary-General Mark Rutte praised Trump's actions against Iran, a sign that the alliance may coordinate further measures. The last time the U.S. and Iran were in open confrontation — the January 2020 killing of Qasem Soleimani — the S&P 500 fell 1.8% over three sessions before recovering within two weeks. This time, the stakes are higher: Iran is producing oil at near-record levels of 3.4 million barrels a day, and any disruption to its exports could tighten global supply by more than 1 million barrels a day.
