LONDON, Aug 8 (Reuters) - Currency trading volumes rose 2.6 percent in July on last year, CLS data showed on Wednesday, although July's volumes were 13.7 percent lower than the previous month of June.
CLS, a major settler of trades in the foreign exchange market, said in a statement that the average daily traded volume of currencies submitted to it reached $1.638 trillion in July, up from $1.596 trillion in the same month in 2017.
July's volumes, however, were lower than June's $1.899 trillion because volatility on forex markets fell.
After double-digit growth - spurred by an uptick in volatility and a big rally in the dollar - to record volumes in the first half of 2018, currency trading growth has slowed in recent months.
Thomson Reuters TRI.TO and NEX Group NXGN.L , which both run large electronic trading platforms, have reported smaller growth for July.
