The People’s Bank of China added 14.93 tonnes of gold in June 2026, its largest single-month purchase since 2023 and its 20th consecutive month of buying.

The Dollar Is Losing Ground. Here’s Why It Matters.

Most dollar headlines are either pure panic or total dismissal. The truth is more uncomfortable.

Here’s what that slow shift actually means for your purchasing power.

Why Are BRICS Countries Buying So Much Gold?

Hormuz Blockade Sent Gold Down 2%. Here’s Why That’s Bullish

The Hormuz blockade sent gold down 2% as oil surged past $100. But margin liquidation — not fundamentals — drove the drop. With CPI at 3.3%, central banks buying, and the petrodollar requiring a navy to defend, the structural case for gold just got stronger.
