Monetary Reserve: What it is, How it Works, History

What Is a Monetary Reserve?

A monetary reserve is a collection of currencies, precious metals, and liquid assets used to redeem national currencies, bank deposits, and meet financial obligations. It is maintained by a country’s central bank or government treasury to regulate the currency and money supply and manage liquidity in global markets. Reserves are an asset in a country’s balance of payments.

In addition to domestic reserves, central banks also hold foreign currency reserves, with the U.S. dollar being the dominant reserve asset.

Key Takeaways

• Monetary reserves refer to the assets held by a central bank or monetary authority.
• Central banks maintain reserves to regulate the money supply in a nation.
• Reserves back up the value of national currencies and can be exchanged or redeemed by note holders and depositors.

Understanding Monetary Reserves

Modern economies are based on the issuance of circulating money through fractional reserve banking. Banks and issuers of deposits hold reserves of cash, marketable assets, and own reserve deposits to meet cash withdrawal demands. Similarly, central banks hold reserves of precious metals, liquid assets, and paper notes against redemption demands from banks and financial institutions, which form the foundation for a country’s money supply.

Monetary reserves are included in a country’s monetary aggregates, which define the money supply. In the United States, these aggregates are categorized as M0, M1, and M2 and include physical currency, money market shares, and savings deposits.

Central banks utilize their reserve assets to manipulate currencies within the economy and also maintain international reserves for global transactions. Reserves can be in the form of gold or a specific currency, such as the dollar or euro.

History of Monetary Reserves

The standards for holding monetary reserves have evolved throughout history. In the past, gold and/or silver were used as the primary reserves, with currencies defined in terms of fixed weights of these precious metals. Banks issued paper notes backed by fractional reserves of gold or silver.

As major powers gained political and economic dominance, gold-exchange standards emerged, where smaller countries pegged their currencies to major countries and held reserves in their currencies. Periodically, countries would halt redemption of their notes and deposits for precious metals, leading to inflation of their paper money supply. Eventually, these countries returned to the gold standard, but inflation became more frequent and longer-lasting, leading to the total breakdown and abandonment of the gold standard during the Great Depression and World War 2.

After World War 2, the Bretton Woods Agreement established a new gold exchange standard among major Western economies. Currencies were valued in terms of U.S. dollars, and countries pledged to maintain fixed exchange rates with the dollar. However, the growing supply of dollars in the global financial markets led to the collapse of the Bretton Woods system.

From 1971 onwards, central banks and monetary authorities began holding a mix of foreign currencies and government debt as monetary reserves. Today, monetary reserves primarily consist of financial instruments that represent promises to pay in the form of future notes. Gold holdings, while still held by some institutions, are not legally linked to the supply or value of national currencies and are not considered monetary reserves.
