Gold and silver both spiked on Wednesday. But the reason might surprise you.
Gold futures opened at $4,835 per ounce - up 3.2% overnight. That's the metal's biggest single-day jump since late November. Silver did even better, surging 7% to hit around $77 per ounce.
Gold is a fear trade. When risk drops, gold usually falls. The Iran ceasefire sent stocks up and oil down - classic signs of calm. Gold should have dropped.
Instead, it rallied. So did silver.
Why? Investors don't fully trust the ceasefire. It's only two weeks long. Missiles kept flying after the deal. Iran's parliament said the U.S. broke terms. This doubt keeps safe-haven gold in demand.
Silver's 7% jump made it the bigger mover for the second day in a row. Over the past year, silver is up nearly 147%. Gold is up about 62%.
Silver tends to move faster both ways. It's smaller, less liquid, and more tied to industry use. When both metals rally like this, it means investors are hedging. Not panicked, but not fully calm.
Gold peaked near its all-time high in January. Its gain for the year was close to 96%. It's come down since then. But at $4,835, it's at levels that seemed wild a year ago.
The ceasefire boosted stocks. Gold holders kept their hedges on anyway.
