Singapore dollar
Unlike many other central banks such as Federal Reserve System, European Central Bank or Bank of England, MAS does not regulate the monetary system via interest rates to influence the liquidity in the system. Instead, it chooses to do it via the foreign exchange mechanism, which it has been doing since 1981. In doing so it manages the Singapore dollar versus a number of currencies that they do not reveal publicly – a Singapore dollar nominal effective exchange rate (S$ NEER). 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. In some circumstances, such as during the COVID-19 pandemic MAS can change the date of its twice yearly meeting.
