A US naval blockade of the Strait of Hormuz, active airstrikes alongside Israel since late February, and a fragile ceasefire that looks increasingly shaky – the Iran conflict of 2026 has created exactly the kind of geopolitical environment that has historically driven up gold mining stocks. He VanEck Gold Miners ETF (NYSEARCA:GDX) has gained approximately 95% over the past year and the conditions driving that streak are not letting up.
GDX is not a gold bullion fund. It has stakes in gold mining companies, meaning it behaves more like a leveraged bet on gold than a direct representative of the metal. When gold prices rise, mining companies see their profit margins expand rapidly because their operating costs are largely fixed. That operating leverage is the driving force here and it cuts both ways.

The fund was launched in May 2006 and now has approximately $28.2 billion in net assets, with a net expense ratio of about 0.5% and a portfolio turnover rate of just 0.5. Its three main holdings, Newmont (NYSE:NEM) at 12%, Agnico Eagle (NYSE:AEM) at 10.8%, and Barrick Mining (NYSE:B) at 7.6%, together they represent almost a third of the portfolio. The geographical diversification is genuine: the fund covers large North American companies, Australian mid-tier companies, African producers and Asian miners.
The portfolio combines business models. Royalty and streaming companies provide more stable cash flows with less operational exposure than pure miners. That combination gives GDX a slightly smoother ride than a pure mining basket, although it still carries substantially higher volatility than physical gold.
US military operations against Iran, including airstrikes since February 28 alongside Israel and a recently announced naval blockade of the Strait of Hormuz following the failed Islamabad talks on April 12, have kept geopolitical risk premiums high across commodity markets. WTI crude oil has risen to around $95 a barrel, up from around $60 at the start of the year. Gold and energy tend to move together in conflict scenarios, and miners benefit from both sides of that trade: higher gold prices and an inflationary narrative that keeps investors seeking exposure to hard assets.
