A central bank is the monetary authority of a country that regulates banks, money supply, and interest rates to achieve monetary stability and economic growth. Central banks were first established in Europe in the 1600s-1800s and most countries had organized their own by the late 1800s. The Central Bank of the Philippines was established in 1948 through the Central Bank Act to maintain monetary stability and promote economic growth. It was formally opened in 1949 and has had several governors throughout its history.
