About US Dollar ($)
The US Dollar (USD, ISO 4217 code 840) is the official currency of the United States, issued by the Federal Reserve System (the US central bank, est. 1913). Subdivided into 100 cents. Banknotes circulate in $1, $2, $5, $10, $20, $50, $100 denominations; coins in 1¢ (penny), 5¢ (nickel), 10¢ (dime), 25¢ (quarter), 50¢, $1. USD is the world's primary reserve currency (~58% of global FX reserves per IMF COFER Q1 2024), the dominant currency in international trade (~88% of foreign-exchange transactions involve USD per BIS Triennial Survey 2022), and the unit of pricing for global commodities (oil, gold, copper, wheat). Also legal tender in Ecuador, El Salvador (alongside Bitcoin since 2021), Panama (alongside Balboa), Zimbabwe, East Timor, and a dozen Pacific island nations. The Federal Reserve targets 2% PCE inflation per its dual mandate (price stability + maximum employment) per the Federal Reserve Act + Humphrey-Hawkins Act 1978.
About Singapore Dollar (S$)
The Singapore Dollar (SGD, ISO 4217 code 702, symbol S$) is the official currency of the Republic of Singapore and is interchangeable with the Brunei Dollar (BND) under the Currency Interchangeability Agreement of 1967 (both nations accept each other's currency at par for transactions). Issued by the Monetary Authority of Singapore (MAS, est. 1971). Subdivided into 100 cents. Banknotes are polymer (since 2007): S$2, S$5, S$10, S$50, S$100, S$1000, S$10000 (the S$10,000 note — featuring the late President Yusof bin Ishak — was the world's highest-denomination banknote until withdrawn from issuance in 2014); coins: 5¢, 10¢, 20¢, 50¢, S$1. MAS uses an unusual monetary policy framework — it manages SGD against a trade-weighted basket of currencies (the 'NEER policy band') rather than setting interest rates directly. Singapore is the world's 3rd-largest FX trading center after London and New York per BIS Triennial Survey 2022 (~9% of global FX turnover).
