What Is S$? Complete Beginner’s Guide to Singapore Currency and Conversions
By Alexander Ross
The prefix S$ exists to eliminate ambiguity in international commerce. Dozens of nations, including the United States, Australia, Canada, and New Zealand, use the generic dollar sign ($). Adding the capitalized "S" prevents cross-border billing mistakes, alerting buyers that an item listed at S$100 is priced in Singapore Dollars, not greenbacks or Australian currency.
In digital clearing houses, financial terminals, and automated bank wires, the symbol gives way to SGD, the three-letter code assigned by the International Organization for Standardization (ISO 4217). The currency traces its sovereign roots to May 1967, when the currency union between Singapore, Malaysia, and Brunei fractured following political independence. Singapore established the Board of Commissioners of Currency, later subsumed by the central bank, issuing the "Orchid" series notes that established the young republic's fiscal identity.
Retail banking apps and e-commerce platforms like Shopify, Stripe, and Amazon display either label interchangeably. Seeing S$, SGD, or SG$ indicates identical legal pricing backed by the treasury of the Republic of Singapore.
