Reserve Management

MAS held S$510.2 billion (US$379.8 billion) of Official Foreign Reserves (OFR) as at 31 March 2021.

Size and Composition of OFR

  • The OFR is invested in a well-diversified portfolio of cash, bonds and equities that aim to provide good long-term returns while being resilient across market conditions. 
  • The portfolio is also diversified across advanced and emerging market economies, and across different currencies.
  • Investment-grade bonds in the advanced economies form the largest allocation in the portfolio. About three-quarters of the OFR are denominated in US Dollar, the Euro, Japanese Yen and Pound Sterling, with US Dollar forming the bulk.

Investment Performance 

  • The investment performance of the OFR over the past 10 years is shown in Chart 1.
  • The gains/losses as represented by the dark red lines, comprise investment gains/losses (blue bars) and currency translation effects (brown bars).
  • In FY2020/21, the total gain was S$8.2 billion, comprising investment gains and negative currency translation effects.
  • MAS recorded an investment gain of S$22.8 billion as global markets recovered strongly during the financial year. The investment gain was mainly from interest income and realised capital gains. 
  • Negative currency translation effects totalled S$14.6 billion due primarily to the strengthening of the Singapore Dollar against the US Dollar and Japanese Yen.
