USDSGD and other managed Asian currencies
Posted: Wed Oct 28, 2026 3:52 am
Not every currency floats freely. The Singapore dollar is managed against a basket, with the central bank using the exchange rate as its main policy tool. Several other Asian currencies are also managed to varying degrees.
For a scalper, that means different behaviour. Moves tend to be smoother and ranges narrower than free-floating pairs. Spreads are wider, since liquidity is thinner and the pair is less central to retail flow. Policy announcements, such as Singapore's twice-yearly exchange rate policy statements, can cause step changes.
The pair's smooth trending nature appeals to some, but costs are a hurdle. With modest ranges and wide spreads, only strategies with larger targets work out.
Trading hours matter. Activity concentrates in Asian hours, and liquidity declines sharply later.
Understanding the regime a currency operates in is key. A managed currency isn't going to behave like a freely floating one, and applying the same strategy blindly often disappoints.
One more consideration is the basket. Because the Singapore dollar is managed against a trade-weighted basket, its movements against the US dollar partly reflect moves in the other currencies in the basket, particularly the yuan, the yen and the euro. That makes USDSGD a quiet indicator of broad Asian currency pressure, which some macro-aware traders use as background.
Any experience with managed Asian currencies, and which strategies fit their behaviour?
