Mark Williamson, chief operating officer of FX cash trading and risk management, said the bank’s blockchain system helped them to save 25 percent in forex trading; “We’re able to demonstrate that this is not a one-off proof of concept or just one or two trades,” Williamson said as reported by CoinDesk; the bank settled more than $250bn worth of transactions in the last month alone; the company has been testing blockchain since 2015 and recently joined a Utility Settlement Coin (USC) project for interbank transactions.
