eToro Group Ltd is introducing interest payments on cash left sitting in trading accounts, offering investors up to 4.3% a year on US dollar balances.
The online trading platform said the rate would be credited monthly and without restrictions, meaning funds could be withdrawn or used for new trades at any time.
The move is aimed at ensuring cash on the sidelines continues to generate a return while account holders wait to reinvest.
Dan Moczulski, managing director of eToro UK, said: “Sometimes the most prudent decision is to wait.
"By paying up to 4.3 % per annum on uninvested US-dollar balances, we ensure clients’ capital continues to earn a competitive return while they prepare for their next trade.”
The payout is determined by an account’s overall size, or “total club balance”, although the rate itself applies only to the available cash portion. Interest is non-compounding.
