New York-based Wahed plans to open a physical branch and bank accounts backed by gold.  The firm aims to attract 3.9 million Muslims in the U.K. with a Sharia-complaint investment management and advice service.  The bank is located on Baker Street in central London and is backed by oil giant Saudi Aramco and French soccer player Paul Pogba.  Wahed bank will also release a debit card that lets users deposit funds with an exchange-traded commodity that tracks the price of gold.  This means consumers are paying for everyday goods with gold.  The bank allows investors to redeem gold in their accounts for physical bars.  Wahid means 'halal' investment platform aligned with Sharia law principles to gain the trust of people belonging to the Muslim faith.  Sharia law forbids charging or earning interest on loans or investing in companies that make most of their money from selling things such as alcohol and gambling. Wahid makes money by charging wealth management fees, which charge users a percentage of their overall asset holdings.
