(Bloomberg) -- Wells Fargo & Co. said it can’t fully meet demand from small businesses rushing to participate in a U.S. relief program because of constraints imposed by the Federal Reserve on the bank’s growth.

The company has capacity to lend $10 billion to small-business clients under the $349 billion U.S. program, but customers already have expressed more interest than that, Wells Fargo said in a statement late Sunday. The firm will therefore focus on helping nonprofits and businesses with fewer than 50 employees.

“While we are actively working to create balance sheet capacity to lend, we are limited in our ongoing ability to use our strong capital and liquidity position to extend additional credit,” Chief Executive Officer Charlie Scharf said in the statement. “We are committed to helping our customers during these unprecedented and challenging times, but are restricted in our ability to serve as many customers as we would like.”

The situation may ratchet up pressure on the Fed to ease the unprecedented asset cap it imposed on the nation’s fourth-largest bank in 2018 in response to mounting scandals at the company. As the coronavirus pandemic began, the firm -- a leading lender to small and midsize U.S. companies, home buyers and commercial property investors -- had about $384 billion of additional lending capacity that it can’t unleash because of the cap.

Friday was the first day that American small businesses hit by the fallout from the coronavirus pandemic could start applying for loans under the new U.S. program. It was part of the $2 trillion stimulus package Congress passed last month aimed at shoring up the economy.

Scharf noted in the statement that Wells Fargo already extended almost $70 billion in new and increased commitments and outstanding loans to consumers, small businesses and corporations in the U.S. last month.
