About Singapore Dollar (SGD)
The Singapore Dollar (SGD) is the official currency of Singapore, managed by the Monetary Authority of Singapore (MAS) under a unique exchange-rate-based monetary policy framework. Instead of setting interest rates, MAS steers SGD against an undisclosed trade-weighted basket (the S$NEER), making SGD one of the most carefully managed floats in the world.
- •MAS uses the S$NEER (Nominal Effective Exchange Rate) as its primary policy tool, not interest rates
- •Singapore is the world's third-largest forex trading hub
- •Singapore has run a current-account surplus every year since 1988
- •MAS announces policy twice a year (April and October)
- •The S$NEER basket composition is not published but is estimated to heavily weight USD, CNY, and MYR

About Indonesian Rupiah (IDR)

Frequently Asked Questions
When is SGD/IDR most liquid?
Liquidity is deepest during the Tokyo and Hong Kong sessions (00:00–08:00 UTC) when SGD markets are open. Spreads widen noticeably during the New York afternoon and Asian public holidays.
What is a typical daily range for SGD/IDR?
Daily ranges vary with volatility regimes. Majors like EUR/USD typically move 0.5–1.2% on quiet days and 2–3% on data-release days. Check the 30-day chart above for a sense of the current range.
What economic events move SGD/IDR the most?
The biggest scheduled catalysts are MAS semi-annual policy statements (April/October) and central bank rate decisions and inflation prints. Geopolitical headlines and global risk sentiment also produce meaningful moves, especially when one currency is a safe-haven and the other is risk-sensitive.
Is it cheaper to convert SGD to IDR at a bank or online?
Online money-transfer services (Wise, Revolut, Remitly, InstaRem) typically offer rates much closer to the mid-market SGD/IDR than traditional banks. Always compare the total delivered amount, not just the advertised "fee" — many providers embed their margin in the exchange rate itself.
Does the SGD/IDR rate change on weekends?
The interbank forex market closes from Friday 21:00 UTC until Sunday 21:00 UTC, so mid-market SGD/IDR rates don't update during that window. Retail broker spreads often widen at Sunday open as Asian desks reopen, so the first few hours of the new week can carry wider execution costs.
