MAS regulate Singapore's monetary system via the foreign exchange mechanism, managing the Singapore dollar versus an undisclosed number of currencies, creating a Singapore dollar nominal effective exchange rate (S$ NEER) since 1981 instead of via interest rates like other central banks such as Federal Reserve System or Bank of England. It carries this out by intervening in the SGD market as well as other operations in the money market. The MAS reviews its policy stance less frequently than most central banks, in a cycle that is around every 6 months.
