Reserve Requirements

Reserve requirements are the amounts of reserves that commercial banks must hold in the form of cash or deposits.

Reserve requirements are set by central banks to control the money supply.

Central banks around the world use a range of policy tools to achieve their monetary policy objectives, such as maintaining price stability, promoting economic growth and ensuring financial stability.

One tool that central banks have long used is to force financial institutions to maintain a certain amount of currency reserves.

What are the reserve requirements?

The reserve ratio refers to the minimum amount of reserves that financial institutions such as commercial banks must hold to cope with deposit liabilities.

These reserves can be held as cash in bank vaults or as deposits at the central bank.

Reserve requirements are usually expressed as a percentage of a bank’s total deposit liabilities and may vary depending on the type of deposit or the size of the financial institution.

What is the purpose of reserve requirements?

The main purpose of reserve requirements is:

  • Ensuring financial stability: By requiring financial institutions to hold certain levels of reserves, central banks can help ensure that these institutions have sufficient liquidity to meet their short-term obligations, reducing the risk of bank runs and promoting overall financial stability.
  • Implementing Monetary Policy: The reserve requirement ratio can also be used as a tool to implement monetary policy by affecting the supply of money and credit in the economy. By adjusting reserve requirements, central banks can influence the amount of funds available for lending, thereby affecting interest rates and overall monetary conditions.
  • Promote the smooth operation of the payment system: Reserve requirements help ensure that financial institutions have sufficient funds to settle interbank transactions and contribute to the smooth operation of the payment system.

How do reserve requirements work?

Central banks typically set reserve requirements as part of a broader monetary policy framework.

They can adjust reserve requirements periodically to reflect changes in policy stance or in response to changing economic conditions.

What will happen if the reserve ratio is increased?

When the central bank raises the deposit reserve ratio, financial institutions need to hold a larger proportion of their deposit liabilities as reserves, thereby reducing the amount of funds available for lending. This could lead to a contraction in the supply of money and credit in the economy, potentially leading to higher interest rates and a tightening of monetary conditions.

What will happen if the deposit reserve ratio is reduced?

When the central bank lowers the deposit reserve ratio, financial institutions can reduce the deposit reserve ratio, thereby increasing the amount of funds available for lending, and may lead to an expansion of the supply of money and credit and a decrease in interest rates.

Do reserve requirements still apply?

Reserve requirements are a traditional tool used by central banks to promote financial stability and help implement monetary policy.

While the RRR remains relevant in some jurisdictions; In several advanced economies, including the United States and the Eurozone, its importance as a monetary policy tool has diminished.

For example, in the United States, as of March 2020, the reserve requirement ratio for all depository institutions is set at 0% of eligible deposits. The elimination of reserve requirements comes after the Fed moved to an "adequate reserves" system, in which the Fed pays member banks interest on the excess reserves they hold.

Central banks in these economies have turned their focus to other policy tools, such as open market operations, interest on reserves and large-scale asset purchases, to achieve their monetary policy objectives.

There are several reasons for this shift:

  • Greater flexibility with alternative tools: Alternative monetary policy tools, such as open market operations and interest on reserve balances, provide central banks with greater flexibility and precision in controlling short-term interest rates and conducting monetary policy .
  • Changes in the Financial System: Technological advances and innovations in the financial system have reduced reliance on reserve requirements as a means of ensuring financial stability and liquidity management.
  • Avoid potential disruptions: Frequent changes in reserve requirements could cause disruptions in the financial system and complicate banks’ liquidity management, leading central banks to prefer more stable and predictable policy tools.

Despite these trends, reserve requirements remain an important policy tool for central banks in many emerging and developing economies.

The relevance of reserve requirements depends largely on the specific characteristics and needs of each jurisdiction’s financial system.
