Central-bank policy covers the interest-rate and liquidity decisions of bodies such as the U.S. Federal Reserve, alongside their guidance about future moves. These decisions ripple through bond yields, the currency, and risk appetite.
For a gold trader, central-bank policy is among the most important macro forces. Because metals are sensitive to real yields and the dollar, shifts in rate expectations or policy tone can move gold sharply. Central-bank gold buying itself is also a recognized source of physical demand.
Policy works through expectations as much as actual decisions, so markets often move on tone and guidance, not just the headline action. Policy context is read together with the economic calendar, real yields, and the dollar rather than as a single isolated driver.
