Central banks
Central banks are national institutions responsible for controlling the commercial banking sector, interest rates, the money supply, and currencies. The concept of central banking dates back centuries, with the first institutions of this kind established in China around a millennium ago, coinciding with the introduction of paper money. Over the centuries, the central bank institution has undergone evolution and enhancement, reaching the current stage of modern banking systems.
Present-day examples of central banks include the US Federal Reserve (Fed), the European Central Bank (ECB), the Bank of England (BOE), the Bank of Canada, the Reserve Bank of Australia (RBA), and others. The influence wielded by a central bank can be confined to a single country, as seen with the RBA, or it can represent the policy of a group or region of countries, exemplified by the ECB. Examining the US Federal Reserve and delving into its policy decisions can illustrate the profound impact of central banking on society.
The US Federal Reserve
Established in 1913, the Fed emerged as a response to the Congress’s determination to establish a stable and secure monetary system in the United States. Currently, the Fed operates by executing monetary policy, with the supervision and regulation of banks also among its principal mandates.
The primary objective of the Federal Reserve, upon its establishment, was to mitigate banking panics, such as the one in 1907 when the New York Stock Exchange experienced a severe 50% decline in stocks from their 1906 highs. Numerous banks and businesses had to close or declare bankruptcy, causing public anxiety about the safety of funds in local banks. This led to a panicked rush to withdraw funds, resulting in significant capital shortages.
One of the main functions of the Federal Reserve is to prevent similar crises. It provides a mechanism for addressing the short-term needs of local banks in cases of massive deposit withdrawals or regional emergencies. In such instances, the Fed lends funds to banks at a nominal charge, known as the discount rate. Once the situation is under control, banks can repay their obligations to the Federal Reserve. This policy is part of the toolkit the Fed employs to ensure the solvency of bank depositories.
Explanation Of Monetary Policy
Monetary policy is also within the Fed’s purview. This term refers to the actions taken by the institution to exert control over the US money supply within the country. Depending on the economic conditions, the central bank may opt for an expansionary or contractionary policy, controlling the money supply through two methods.
During economic slowdowns, the Fed often considers adopting an expansionary policy. Initially, the monetary base expands, and interest rates decrease. The essence of the expansionary policy is to make money more accessible to both banks and businesses, fostering growth and development. The intended outcomes include an increase in GDP and a reduction in the unemployment rate.
Conversely, after a period of rapid economic expansion, or when the economy is at risk of overheating, the Federal Reserve may implement a contractionary policy. In this scenario, the central bank contracts the monetary base and raises the main interest rates. This makes excess capital scarcer, imposing a higher premium on lending and initiating an economic slowdown. During contractionary periods, the GDP is expected to decrease, and the unemployment rate may rise.
Impact On Currency Exchange Rates
The decisions made by the Fed have a direct impact on money supply and demand, regulate interest rates, and consequently influence the strength or weakness of the USD. An expansionary policy leads to an increase in the monetary base and a decrease in interest rates, resulting in an oversupply of money and a depreciation of the currency. Conversely, a contractionary policy leads to capital scarcity, causing the currency to appreciate. For FX traders, monitoring the policy cycle of central banks
