Central Bank Reserves

Definition
Central bank reserves are the assets a national monetary authority holds to back its currency and manage its economy, including foreign currencies, government bonds, and gold. Gold held in these reserves is a significant and recurring source of demand in the metals market.
Most major central banks hold gold as part of their reserves, and their buying decisions affect the broader market.
Why it matters
Central banks are among the largest holders of gold in the world. In recent years many have added to their gold reserves, and this institutional buying is a steady, often price-insensitive source of demand. Because central banks act on long horizons, their accumulation differs from the shorter-term trading that drives much of the daily price.
In practice
A central bank may hold gold alongside foreign currencies to diversify, to reduce reliance on any single currency, and as an asset with no issuer that can default. Holdings are typically reported to bodies such as the International Monetary Fund.
How it’s used
Reserve data is watched as a gauge of long-term demand. Sustained central bank buying is frequently mentioned as one structural support for gold prices.
