China is not hedging. It's escaping. (Ad)

China's US Treasury holdings have fallen from a peak of $1.32 trillion to roughly $659 billion, an 18-year low. Beijing's central bank has bought gold for 20 straight months, its longest streak in a decade. Goldman Sachs estimates China's real gold buying is 4.8 times the official figure. The European Central Bank confirms gold has overtaken US Treasuries as the world's top reserve asset, at 27% versus 22%. As foreign demand for US debt fades, rates and everyday costs may feel the pressure.tc pixel

Trump's Next Move Could Shrink Your Dollar (Ad)

There's a plan in Washington being called the 'Mar-a-Lago Accord' - a deliberate strategy to weaken the U.S. dollar through tariffs, currency pressure, and coordinated policy shifts designed to boost American exports. A weaker dollar means every dollar you've saved buys less - quietly, without a headline or a warning. Smart investors are already repositioning before the slide accelerates.tc pixel
