Singapore’s unusual monetary arrangements have long included a currency board-type backing of domestic currency and a structural government surplus; it liberalised financially relatively early, tried exchange rate pegging but found it more efficient to vary the exchange rate to offset external inflationary pressures, and by 1986 this had become an idiosyncratic but systematic form of inflation targeting.

Years Targets and attainment Classification
1974-75 currency floating, no other targets but concern with price stability; domestic financial liberalisation by mid-1975, with monetary operations moving from credit ceilings to rediscount facilities and reserve requirements; domestic currency backed by forex reserves as in currency board loosely structured discretion LSD
1976-80 currency pegged to undisclosed basket (within undisclosed margins); full capital account liberalisation by 1978, active autonomous forex market; monetary policy operated via indirect instruments, increasingly forex swaps; government budgetary operations typically contractionary loose exchange rate targeting LERT
1981-85 more active variation of exchange rate (in form of appreciation) to maintain confidence in currency and offset external inflationary pressures, but with eye to competitiveness and growth as well loosely structured discretion LSD
1986-2014 active exchange rate control (with first deliberate depreciation 1986-7) is by now developing into a form of sui generis inflation targeting, where centre, path and width of exchange rate band are set at intervals in forward-looking way so as to maintain price stability (informal target generally understood as less than 3%); this monetary strategy becomes more formalised and more publicised over time, with gradual increases in transparency, e.g. direction of exchange rate movement announced in broad terms twice each year from mid-2001 (but neither exchange rate index nor exact centre, rate of crawl and width of band are published, nor is the formal inflation target); implied inflation targets mostly met or near-met; government budgetary operations contractionary; monetary policy operated mainly through forex swaps, but also via government bond repos and direct borrowing/lending with banks loose inflation targeting LIT
