Metro Bank, once a promising British lender, has faced significant challenges in recent years. From accounting scandals to a declining share price, the bank's future has been uncertain. However, Colombian billionaire Jaime Gilinski's recent investment might offer a lifeline. Founded in 2010 by Vernon Hill, Metro Bank was Britain's first new mainstream bank in over a century, the first challenger bank. The market cap collapsed to £86 million, down from £3.6 billion in 2018.
