Direct answer: “trillion traded in forex per week”
There is no single universally correct value for “how much trillion is traded in forex per week.” Reported forex turnover totals differ because sources publish different metrics (for example, daily vs weekly), use different time windows, and measure turnover using specific accounting rules.
A practical way to translate available published information into a “per week” view is to start with a reported daily turnover figure (in currency units) and multiply by the number of trading days you assume (often about five business days). This yields an estimated weekly gross turnover in “trillions,” but only for the same dataset and definition.
How it works (definitions and mechanics)
Forex turnover is typically reported as gross turnover, meaning buy and sell activity is counted in a way that can include both sides of trades rather than only the economic net flow. That choice alone can materially change a “trillion per week” number.
Also, “per week” totals require an assumption about the time window. Many datasets provide daily turnover estimates, and turning that into a weekly amount means choosing how many days to include. If a source uses “business days” rather than calendar days, a “weekly” multiplier changes.
Finally, the currency unit matters. Forex turnover is often reported in a base currency such as US dollars, so the reported “trillion” scale can depend on the reporting currency and exchange-rate context.

Example checks you can do independently
- Pick one source that provides a daily forex turnover number stated in a clear unit.
- Convert to a weekly figure by multiplying by five business days (or the exact number of days the source implies).
- Confirm the definition is gross turnover and that the unit is consistent (for example, currency per day in US dollars).
- If another source gives a different “trillion per week” value, compare definitions first—not just the headline scale.
These steps let you verify whether two “trillion per week” figures are actually measuring the same concept.
Limitations and uncertainty
Because no real-time dataset is assumed here, any “trillion per week” statement must be treated as definition-dependent and source-dependent. Even with the same general concept (forex turnover), differences in gross vs net accounting, reporting units, and the chosen number of trading days can change the weekly total.
So the most verifiable claim you can make is conditional: “Given daily turnover of X in source Y and assuming N business days, the implied weekly gross turnover is X × N.” Without the specific source and definitions, a single number for “trillion per week” cannot be stated reliably.
