To trade us stocks from singapore, the biggest adjustment is the clock. The US market runs while Singapore sleeps, so knowing the hours, the settlement rules and the tax makes trading far calmer. This guide covers when the US market is open in Singapore time, how extended hours work, and the tax points to keep in mind.

What Are US Market Hours in Singapore Time?
The US regular session runs from 9:30 am to 4:00 pm New York time. Because New York observes daylight saving for part of the year, the Singapore equivalent shifts. The table below shows both.
| Session | New York time | Singapore time |
| Regular (Mar to Nov) | 9:30 am to 4:00 pm | 9:30 pm to 4:00 am |
| Regular (Nov to Mar) | 9:30 am to 4:00 pm | 10:30 pm to 5:00 am |
| Pre-market | From about 4:00 am | Earlier in the evening |
| After-hours | To about 8:00 pm | Into the morning |
US market hours in Singapore time; the one-hour shift follows US daylight saving.
How Do Extended Hours Work?
Beyond the regular session, US markets offer pre-market and after-hours trading. These windows let you react to news, such as an earnings release, before or after the main session, which is convenient when the regular hours fall in the middle of the Singapore night. The catch is liquidity: fewer buyers and sellers are active, so prices can move more sharply and spreads widen. A limit order is the safer choice in extended hours, since it caps the price you pay or accept rather than filling at whatever is available.
What Should You Know About Settlement and Tax?
US equities settle one business day after the trade, known as T+1, so the cash and shares change hands quickly. On tax, US dividends paid to Singapore investors are reduced by a 30% withholding tax, taken before the money reaches you, while Singapore does not tax your capital gains. US estate tax can also apply to a non-resident’s US shares above US 60,000 dollars. None of this stops you trading, but it shapes your net return, so factor it in and seek professional advice for larger holdings.
