In thirty seconds
- USDSGD prices the dollar in Singapore Dollars. A quote of 1.3420 means one US Dollar buys 1.3420 SGD.
- The MAS does not set interest rates as its main lever. It steers the SGD inside an undisclosed band against a basket of partner currencies. That policy unique-ness is the entire story behind the chart.
- Two scheduled releases each year, in April and October, drive most of the annual move. Outside those windows, daily ranges of 0.2 to 0.5 percent are normal.
- On LHFX you trade USDSGD on MT5 with STP/ECN execution, $3 commission per side, and leverage up to 1:500. A 0.15 lot ticket needs roughly $30 of margin at the cap.
- Liquidity is best across the Singapore session (21:00 to 05:00 ET) and the London open. Sizing should respect the calendar concentration of risk.
How the pair is quoted and what a pip is worth
USDSGD is a direct quote against the dollar, with the dollar in front. The pip is the fourth decimal place, the same convention used on most majors.
If the screen reads 1.3420, you are being told that one US Dollar will purchase 1.3420 Singapore Dollars. A move from 1.3420 to 1.3421 is a single pip. A move from 1.3420 to 1.3470 is fifty pips. Because the quote currency is SGD, every pip is initially valued in SGD and then converted back to your account base.
On a 0.10 standard-lot trade (10,000 units of USD notional), one pip is roughly 1 SGD, which translates to about 0.75 USD at a 1.3420 rate. Scale that to a 1.0 lot ticket and a single pip is closer to 7.45 USD. Spread costs on USDSGD are wider than on EURUSD because Asian liquidity sits in fewer hands, but the structural calm of the pair often offsets the carry cost over an average week.
Two quoting quirks matter in practice. First, the dealing screen always rounds to four decimals, so the smallest visible increment is a full pip rather than a tenth-pip (sometimes called a pipette). Second, because the SGD is itself basket-priced, intraday quotes can move while EURUSD and USDJPY sit still, which is the visual signature of the basket recomputing under the surface.
Pip value at a 1.3420 quote
| 0.01 lots (1,000 units) | 0.10 SGD | ~0.07 USD |
| 0.10 lots (10,000 units) | 1.00 SGD | ~0.75 USD |
| 0.50 lots (50,000 units) | 5.00 SGD | ~3.72 USD |
| 1.00 lot (100,000 units) | 10.00 SGD | ~7.45 USD |
Why the MAS framework changes the trade
Every other major central bank publishes a policy rate and then watches its currency adjust. The Monetary Authority of Singapore inverts that order. The exchange rate is the target; the interest rate is the residual.
In practice, this means three things for anyone looking at USDSGD.
First, the SONIA-equivalent for Singapore (SORA) is not a USDSGD driver in the way the federal funds rate is. The MAS does not hike or cut a benchmark rate to defend the SGD. It simply tells the market a fresh target slope, level, or width for the basket band, and lets short rates settle wherever cross-border arbitrage leaves them.
Second, the basket itself is opaque. Market estimates place CNY, MYR, JPY, EUR, IDR, KRW, and a handful of others inside the basket, with weights revisited periodically. Because no public formula exists, USDSGD price discovery during stress depends on traders triangulating from the moves of those component currencies in real time. When CNY weakens sharply against the dollar, expect SGD to follow with a lag and a smoothed amplitude.
Third, only two scheduled dates a year really matter. The April and October Monetary Policy Statements collapse the pair's information rate. A surprise band recentring or slope steepening can mark out 1.5 percent inside the first session and a further percent over the next forty-eight hours. Many desks treat the seven calendar days around each statement as a discrete trading regime, with reduced gross exposure heading in and a fresh framework once the new policy direction is visible.
The practical takeaway is that USDSGD rewards calendar-aware traders more than chart-pattern traders. A clean head-and-shoulders set up two weeks before an MAS release is far less reliable than the same set up three weeks after one.
A short history of the band
The current managed-float framework dates to 1981. The mechanics have evolved, but the philosophy of using the exchange rate as the primary lever has not changed in more than four decades.
Singapore exited the sterling area in 1973 and briefly experimented with a free float. By 1981, the MAS had concluded that for an open, small, trade-dominated economy, importing or exporting inflation through the exchange rate was more powerful than steering it through domestic short rates. Since then, the framework has been a managed float against a trade-weighted basket inside a policy band, with the slope, level, and width adjusted as conditions warrant.
The band has been recentred multiple times in response to major shocks. The 1997 Asian Financial Crisis saw a widened band to absorb regional volatility. In April 2020, against the early COVID dislocation, the MAS recentred lower and flattened the slope to zero, the first time it had moved to a neutral basket-appreciation stance in years. By October 2022, with imported inflation pressing higher, three back-to-back tightening moves had restored a steeper appreciation path against the basket.
Reading the historical sequence of MAS statements alongside a long-run USDSGD chart shows the recurring pattern: a basket recentring move tends to print a multi-week trend, a slope adjustment tends to print a multi-quarter trend, and a width change tends to print a multi-month volatility regime. Knowing which lever was pulled at the last meeting is often more useful than knowing the absolute level of the pair.
What pushes USDSGD around
The pair has fewer drivers than most majors, but each one carries more weight per release because the calendar is so concentrated.
MAS Monetary Policy Statements
April and October. The single most consequential event for USDSGD. Direction, slope, and width changes all leave fingerprints on the chart for weeks afterwards.
Federal Reserve policy
USD is half the quote. FOMC decisions, dot-plot revisions, and Fed Chair press conferences move USDSGD, although the basket structure tends to dampen the magnitude compared with USDJPY.
Basket-component currencies
Sharp moves in CNY, MYR, JPY, EUR, or IDR feed through the basket. Watching offshore CNY (USDCNH) during Asia hours is the most reliable real-time proxy.
Singapore CPI and core CPI
Released monthly by SingStat. The series sets the inflation backdrop the MAS is reacting to and shapes the next semi-annual statement.
Trade and tariff headlines
Singapore is a re-export hub. Any escalation in US-China trade frictions or regional tariff disputes shows up in USDSGD because of the basket exposure to CNY and the city-state's role in regional logistics.
Risk-on, risk-off cycles
SGD is the safest of the Asian EM-adjacent currencies. In broad risk-off episodes, SGD typically outperforms within the basket, pulling USDSGD slightly higher but less than the EM peer group.
When the pair actually trades
USDSGD is technically open from 17:00 ET Sunday through 17:00 ET Friday, but liquidity is far from uniform across the week.
| Singapore prime window | 21:00 to 05:00 ET | Singapore banks, regional treasuries, and Asian corporate flow are all live. Tightest spreads of the week, deepest two-way book. |
| London handover | 03:00 to 08:00 ET | European banks pick up the book before Asia closes. Reasonable liquidity, occasional widening into the London fix at 11:00 ET. |
| New York session | 08:00 to 16:00 ET | US data days and Fed releases move the pair through the dollar leg. Acceptable spreads, lower depth than Asia. |
| Late New York lull | 16:00 to 19:00 ET | Thinnest part of the day. Spreads can drift two or three times their daytime average. Limit orders only. |
USDSGD against its nearest peers
Most retail traders pick a single Asian dollar-cross to express a regional view. USDSGD competes with USDJPY, USDCNH, and USDHKD for that slot. The table below shows where each pair sits on the spectrum.
| Pair | FX regime | Typical daily range | Calendar risk | Best fit for |
|---|---|---|---|---|
| USDSGD | Managed float against basket band | 0.2 to 0.5% | Two MAS dates a year (April, October) | Calendar-aware swing trades, lower-volatility carry |
| USDJPY | Free float, occasional MoF/BoJ intervention | 0.4 to 1.2% | Eight BoJ dates, intervention risk | Macro directional, yield-spread trades |
| USDCNH | Daily PBoC fix, soft band | 0.3 to 0.7% | Daily fix at 09:15 Beijing, ad-hoc PBoC actions | China-macro themes, basket-spillover hedges |
| USDHKD | Hard peg, 7.75 to 7.85 band | Often <0.1% | HKMA convertibility undertaking, rate arbitrage | Pure rate-differential carry, not directional |
USDSGD sits between the rigid USDHKD peg and the free-float USDJPY. The result is a pair that gives you genuine directional opportunity, but with the timing dictated by a known calendar rather than by continuous policy noise.

Worked example: a swing trade two weeks after an MAS release
Set the scene with a $3,500 account and a USDSGD quote of 1.3420. The October statement has come and gone two weeks ago. The MAS recentred the band slightly higher, and the post-statement consolidation has settled into a low-volatility regime.
You open a 0.15 lot long ticket. Notional exposure is 15,000 US Dollars, and the margin requirement at the 1:500 cap is $30, around 0.9 percent of the account. Commission on the round trip will be $9.
Your stop sits 35 pips below entry, at 1.3385. One pip on a 0.15 lot ticket is worth roughly 1.12 USD, so a 35-pip stop translates to about 39 USD of risk, or 1.1 percent of the account. Your take-profit is 70 pips above entry at 1.3490, a 2:1 reward-to-risk ratio aligned with the post-statement drift the band recentring suggested.
Two weeks later the pair prints 1.3490 inside a calm London session. You exit for a 70-pip gain, about 78 USD before costs, 69 USD after the $9 round-trip commission. That is a 2.0 percent net return on the account, achieved with leverage well inside the 1:500 cap.
If the same trade had been structured in the first week of April or October, the 35-pip stop would have been undersized for the policy-statement environment. A 70 to 90-pip stop, paired with a smaller 0.07 to 0.08 lot ticket, would carry the same dollar risk while accommodating the statement-day volatility.
Where the pair can hurt you
USDSGD is calm most of the time, which is precisely why the rare violent moves catch leveraged retail accounts. Three risks deserve attention before sizing any position.
Policy-statement gap risk
April and October MAS statements can recentre the band, change its slope, or widen its width without warning. Single-session moves of 1.5 to 2.5 percent are part of the recent record. The fix is calendar discipline: cut gross exposure in the week before the statement, flatten leveraged tickets the day before, and re-engage only once the new framework is visible, typically 24 to 48 hours after the release.
Basket-opacity risk
Because the MAS does not publish the basket weights or the band parameters, price discovery during regional stress can lag traders' expectations. The pair may move sharply while it remains unclear which basket component (often CNH) is doing the heavy lifting. The fix is to keep CNH, JPY, and EUR open in adjacent windows so the basket signal is interpretable in real time.
Calendar-concentration risk
Most of a year's USDSGD move is delivered in a small number of sessions. Sizing a position from average daily range alone systematically underestimates tail risk. The fix is to think in annual percentile terms: a 0.4 percent move is a median day, a 2.0 percent move is a typical MAS day, and account sizing should accommodate the latter even when you trade the former.
