What Time Does Forex Open in GMT and UTC?
The forex week reopens as Monday arrives in the Pacific: trading starts in Wellington, New Zealand, and the Sydney session begins at 9:00 AM Monday local time, cited as 10:00 PM GMT (Greenwich Mean Time) Sunday (Axi, a forex broker: Forex Market Hours: Trading Sessions & Opening Times - Axi, retrieved 2026-10-14).

What time does forex open in GMT or UTC?
The clearest documented figure comes from Axi: the Sydney session begins at "9:00 AM Monday local time, which is 10:00 PM GMT Sunday" (Forex Market Hours: Trading Sessions & Opening Times - Axi, retrieved 2026-10-14). That is the answer to the narrow question of when the Sydney session, the market's conventional opening block, begins; the week's very first trades start earlier in Wellington.
Expressed in UTC, the same cited example is 22:00 UTC on Sunday.
Ordane calculation, the London window in both seasons: 16:00 minus 07:00 is 9 hours in summer, and 17:00 minus 08:00 is 9 hours in winter, so the seasonal change is a 1-hour shift of the same 9-hour window, not a change in its length. Method: end time minus start time for each window cited from Capital.com below; no other inputs.
Why that hour must be checked against the date and Sydney offset
That 10:00 PM figure is a conversion, not a permanent rule: it reflects the offset in effect for the source's example. Session windows do shift with the seasons; the cited London table lists 7:00 AM to 4:00 PM UTC in summer and 8:00 AM to 5:00 PM in winter (Forex Market Hours - Capital.com, retrieved 2026-10-14). Always confirm which offset applies to your date before relying on a converted hour.
Does Wellington or Sydney open first?
Even though trading starts in Wellington, the opening block is labeled the Sydney session. Market convention groups New Zealand's early activity under the Australian session name, which is why most guides and most search results present Sydney as the market's opening center. So if you see "forex opens with the Sydney session," that is conventionally correct, even though the first Monday-morning trades originate in Wellington.
Wellington reaches Monday before Sydney
Trading starts in Wellington on Monday morning while it is still Sunday in most of the world (Forex Trading Sessions - BabyPips, retrieved 2026-10-14). Because New Zealand is ahead of Australia in local time, the calendar reaches Monday there first, so the weekly reopening is triggered by Wellington, not Sydney.
How do you convert the forex opening time to UTC?
| Field | Value |
|---|---|
| Local opening | 9:00 AM Monday, Sydney time |
| Cited conversion | 10:00 PM GMT Sunday |
| Status | Valid only for dates when the offset used by the source applies; re-verify per Step 2 for any other date |
Because no single UTC hour is valid year-round, use a repeatable three-step method whenever you need the opening time for a specific date.
- Identify the supported local opening time.
- Verify the center's UTC offset on the relevant date.
- Convert and record the result with its date.
Step 1: identify the supported local opening time
Start from the documented local time, not the conversion: the Sydney session opens at 9:00 AM Monday local time. Local times are the stable reference, because actual open and close times are based on the local business hours of each trading center, with most business hours starting somewhere between 7:00 AM and 9:00 AM local time (Forex Trading Sessions - BabyPips, retrieved 2026-10-14).
Step 2: verify the center's UTC offset on the relevant date
Look up Sydney's UTC offset for the exact Sunday in question using a current time-zone reference. Never reuse an offset from a different season or from memory.
Step 3: convert the local time and retain the checked date
Conversion box (date-specific, cited example only):
| Field | Entry |
|---|---|
| Local opening | 9:00 AM Monday, Sydney |
| Converted hour | 10:00 PM GMT Sunday (22:00 UTC) |
| Valid for | Dates on which the source's Sydney offset applies |
| Checked against | Step 2 offset verification for your specific date |
What does the evidence establish?
The table shows what the supplied sources establish and where they stop. Missing dated UTC offsets are the key gap: none of the cited material pins a UTC opening hour to a specific calendar date, which is why the conversion method above matters more than memorizing one hour.
| Question | Supported answer | Limitation |
|---|---|---|
| Which trading centers does the evidence name? | Four: Sydney, Tokyo, London and New York (What is Forex (FX) Trading and How Does it Work? - IG, retrieved 2026-10-14) | No opening hours given for Tokyo, New York or Wellington |
| What is the Sydney opening time? | 9:00 AM Monday local time; 10:00 PM GMT Sunday | The GMT figure is a dated conversion, not a year-round UTC rule |
| Where does trading actually begin? | Wellington, on Monday morning, under the Sydney session label | No Wellington clock time is supplied |
| How are session openings defined? | By local business hours of each center, typically starting 7:00 to 9:00 AM local time | Not a full session schedule |
| Does London's window vary? | Yes: the cited table distinguishes summer and winter London windows (7:00 AM to 4:00 PM summer UTC; 8:00 AM to 5:00 PM winter) (Forex Market Hours - Capital.com, retrieved 2026-10-14) | Seasonal windows only; no other centers' windows given |

FAQ about when forex opens
Direct answers about the forex opening time in GMT and UTC.
What time does forex open on Sunday in GMT?
The cited example is 10:00 PM GMT on Sunday, corresponding to Sydney's 9:00 AM Monday local opening; the week's first trades start earlier in Wellington. Treat the GMT figure as a date-dependent conversion, not a fixed constant. Source: Forex Market Hours: Trading Sessions & Opening Times - Axi, retrieved 2026-10-14.
Is 10:00 PM GMT the opening time all year?
No, the evidence does not establish that. The figure reflects the offset in effect when the source's example applies, and Sydney's offset changes with daylight saving time, so the converted hour can differ on other dates. Source: Forex Market Hours: Trading Sessions & Opening Times - Axi.
Why can daylight saving time change the UTC conversion?
Session openings are anchored to local business hours. When a center shifts between standard and daylight time, its UTC offset changes, so the same local opening hour maps to a different GMT/UTC clock time. The London table's separate summer and winter windows illustrate this seasonal variation. Source: Forex Market Hours - Capital.com, retrieved 2026-10-14.
Does Wellington reach Monday before Sydney?
Yes. Trading starts in Wellington on Monday morning while it is still Sunday elsewhere, though the block is conventionally named the Sydney session. Source: Forex Trading Sessions - BabyPips.
How can I verify the opening time for a specific date?
Follow the three-step method: confirm the 9:00 AM Monday local opening, check Sydney's UTC offset for that date with a current reference, and convert. Record the date you checked. Source: Forex Market Hours: Trading Sessions & Opening Times - Axi.
