Woori Bank has introduced a service that allows customers to pay additional fees that can arise after an overseas remittance without visiting a branch. The bank said on Aug. 14 it will implement a non-face-to-face foreign exchange fee payment service. Individual users of the Woori WON Banking app can check the amount due, complete security authentication and pay from a won-denominated deposit and withdrawal account in their own name. Cable charges can also be paid this way.

BitMEX co-founder Arthur Hayes said U.S. Federal Reserve dollar liquidity provision could expand as Japan seeks to push up the yen. He outlined a scenario using the Fed’s FIMA repo facility, in which Japan posts U.S. Treasuries as collateral to borrow dollars, sells them for yen and then invests the yen in domestic assets. Hayes said this could expand the Fed’s balance sheet and channel liquidity into bitcoin, ether, gold and gold miners.
