Wells Fargo ($WFC@US) is scaling back its multitrillion-dollar market for mortgages amid regulatory pressure and rising interest rates. Regulators have tightened oversight of mortgage lending in the past decade, and Wells Fargo has been under scrutiny after its fake accounts scandal in 2016. Wells Fargo was the top lender until 2019, with $201.8 billion in volume. Mortgages are the largest category of debt held by Americans, making up 71 percent of the $16.5 trillion in total household balances.
