How SGD/IDR Exchange Rates Work
Exchange rates are determined by supply and demand in the global foreign exchange (forex) market, the largest financial market in the world with over $6 trillion traded daily.
Floating vs Fixed Rates: Most major currencies like SGD and IDR have floating exchange rates, meaning their value is determined by market forces. Some currencies are pegged to another currency (usually USD) at a fixed rate.
Bid and Ask Prices: In forex markets, currencies are quoted with a bid price (what buyers pay) and ask price (what sellers receive). The mid-market rate shown on this page is the midpoint between these two prices.
Rate Fluctuations: The SGD/IDR rate can change every second during trading hours. Major economic announcements, interest rate decisions, and geopolitical events can cause significant moves in either direction.
