Gold prices fell following the Federal Reserve's monetary policy announcement. There, Chairman Jerome Powell essentially hinted at a 'higher for longer' approach, causing financial markets to price in a higher eventual Federal Funds rate and pushing back expectations of a cut interest rates in the near future.
In response, Treasury yields and the US dollar increased, working together to put downward pressure on precious metals, such as gold and silver. On the daily chart below, XAUUSD has rejected the short-term downtrend line recently formed from July. That opened the door for a revisit of growing support from April, which is closely linked to the 38.2% Fibonacci retracement of 1903.46.
