(Bloomberg) -- Silvergate Capital Corp. plans to wind down operations and liquidate its bank after the crypto industry’s meltdown sapped the company’s financial strength, sending shares plunging.

“In light of recent industry and regulatory developments, Silvergate believes that an orderly wind down of bank operations and a voluntary liquidation of the bank is the best path forward,” the company said in a statement late Wednesday. “The bank’s wind-down and liquidation plan includes full repayment of all deposits.”

Silvergate collapsed amid scrutiny from regulators and a criminal investigation by the Justice Department’s fraud unit into dealings with fallen crypto giants FTX and Alameda Research. Though no wrongdoing was asserted, Silvergate’s woes deepened as the bank sold off assets at a loss and shut its flagship payments network, which it called “the heart” of its group of services for crypto clients.

“Today we are seeing what can happen when a bank is over-reliant on a risky, volatile sector like cryptocurrencies,” Senator Sherrod Brown, chair of the Senate Banking, Housing, and Urban Affairs Committee, said in a statement. “When banks get involved with crypto, it spreads risk across the financial system and it will be taxpayers and consumers who pay the price.”

The company told investors March 1 that it was reviewing whether it would be able to stay in business. The last bank failure in the US was in 2020, according to the FDIC’s website, which listed four during the first year of the pandemic. Because Silvergate was voluntarily liquidated, the regulator doesn’t count it in its official tally.

Silvergate’s shares were trading down as much as 49% to $2.5 in US premarket trading on Thursday. The stock topped $220 in November 2021.

The firm’s collapse could “put even more pressure on banks to demonstrate that their dealings with crypto are safe and sound,” Hilary Allen, a law professor at American University who’s testified before Congress on FTX, said earlier.

Senator Elizabeth Warren, a critic of Wall Street who has warned of the dangers posed to the financial system by crypto, said Silvergate’s activities have been “risky, if not illegal,” and that the firm failed in its due diligence.

“As the bank of choice for crypto, Silvergate Bank’s failure is disappointing, but predictable,” she said in a tweet. “Now, customers must be made whole & regulators should step up against crypto risk.”

The ramifications of Silvergate’s demise continue to ripple through the crypto sector. Marathon Digital Holdings Inc. terminated its loan with the bank, reducing the digital-asset miner’s debt by $50 million. Binance Holdings Ltd.’s Chief Executive Officer Changpeng Zhao said in a tweet that his exchange, the world’s largest, does not have asset losses at Silvergate.

Silvergate opened for business in 1988 to make loans to industrial clients, and filings show that it dealt in conventional services such as commercial and residential real estate lending. But in 2013, the La Jolla, California-based company started to pursue crypto clients. 

The idea was to pile up noninterest bearing deposits associated with services to those customers and then plow the money into what it described as a conservative portfolio of investments in interest-bearing cash at other banks, short-term securities, and loans “that we believe generate attractive risk-adjusted returns.” 

The crypto-focused services enabled clients to route their money through the company’s proprietary platform and send it to each other to pay for digital assets. The network handled only US dollars and euros; the actual trades of virtual currencies didn’t take place on Silvergate’s system.

With its crypto business growing, Silvergate went public in 2019, telling investors in its prospectus to expect an even bigger shift toward crypto. Eventually the company’s Silvergate Exchange Network helped attract $11.9 billion in digital assets held as deposits as of Sept. 30.

Three months later, after FTX had collapsed into bankruptcy amid charges of fraud, crypto deposits fled and left Silvergate with only $3.8 billion, according to a Jan. 5 statement. FTX was one of its biggest customers, and the sudden drop forced Silvergate to sell securities before they matured at steep losses that eroded its capital and liquidity.  

The bank’s crisis intensified on March 2 when investors and business partners were spooked by fresh disclosures of the bank’s difficulties and headed for the exits. Coinbase Global Inc., Galaxy Digital Holdings Ltd., Paxos Trust Co. and other crypto firms decided to stop accepting or initiating payments through Silvergate.

In its statement Wednesday, Silvergate said it is “considering how best to resolve claims and preserve the residual value of its assets, including its proprietary technology and tax assets.”

In the end, said Aaron Klein, a senior fellow with the Brookings Institution who studies financial technology and regulation, the outcome isn’t all that surprising. “There’s nothing new here,” he said. “Borrowing short and lending long has been the subject of bank failure for centuries.”
