Due to rounding, numbers presented throughout the document may not add up precisely to the totals provided and percentages may not precisely reflect the exact figures.
From January 2017, CLS altered the reporting methodology for the FX data it makes available on a monthly basis. The data provided is based on executed trade volumes submitted to CLS. It is adjusted to equate to the same reporting convention used by the Bank for International Settlements (BIS) and the foreign exchange committees’ semi-annual FX volume surveys. These surveys only report one side of any trade, and only one of the four legs of FX swap trades, to avoid double counting the total amount of trades.
