Reserve Assets

DEFINITION of 'Reserve Assets'

A reserve asset is an asset that is readily available to monetary authorities to use for a number of purposes. To reconsidered a reserve asset it must be an external physical asset that is, in some part, controlled by policymakers. The asset should be easily transferable. 

Reserve assets include currency, commodities, or other financial capital held by monetary authorities, such as central banks, to finance trade imbalances, check the impact of foreign exchange fluctuations and address other issues under the purview of the central bank. They can also be used to restore confidence in financial markets. 

BREAKING DOWN 'Reserve Assets'

Before the Bretton Woods agreement ended in 1971, most central banks used gold as their reserve assets. Today, central banks may still hold gold in reserve, but this has been supplanted by reserves of foreign currencies. Currencies held by central banks have to be readily convertible, meaning that the currency should have high enough stable demand (and low controls) to allow the bank to use them.

Reserve assets can be used to fund currency manipulation activities by the central bank. In general, it is easier to push the value of a currency down than to prop it up, since propping the currency up involves selling off reserves to buy domestic assets. This can burn through reserves quickly. The central bank can put downward pressure on the currency by adding more money into the system and using that money to buy foreign assets. The downside to this strategy is the potential for increased inflation.

The U.S. dollar is widely considered to be the predominant reserve asset, and because of this, most global central banks will hold a substantial amount of U.S. dollars.
