Customer deposits at US retail forex brokers rose in July for the first time in four months, then edged lower in August. The six registered dealers owed retail clients $469.96 million at the end of August, according to Commodity Futures Trading Commission (CFTC) data.
July added $9.27 million, a 2.01% increase that lifted the total to $471.58 million. That followed June's $462.31 million, which FinanceMagnates.com reported in August as the lowest since at least September 2023. August took back $1.61 million, or 0.34%.

The recovery has not closed the gap with last year. The August total is 7.23% below the $506.58 million held in August 2025, the widest annual shortfall since March, and still under the January level that FinanceMagnates.com described at the time as the lowest in more than two years.
Gain Capital Accounts for Most of July's Increase
Gain Capital, the StoneX subsidiary behind FOREX.com, held $204.12 million in July, up 3.57% on June. Its $7.03 million gain was about three-quarters of the industry's net increase for the month.
