Crypto assets were hammered on Monday after crypto lending platform Celsius paused withdrawals, speaking fears of a solvency issue at the company which could spread to other parts of the market.

Celsius said withdrawals, swaps, and transfers between accounts would be halted because of “extreme market conditions” and that the move was meant to “stabilize liquidity and operations.”

“We are taking this action today to put Celsius in a better position to honor, over time, its withdrawal obligations,” the company said in a memo.

Then one of the world’s largest cryptocurrency exchanges Binance stopped withdrawals.

Meanwhile, Binance, the world’s largest crypto exchange, halted bitcoin withdrawals for over three hours “due to a stuck transaction causing a backlog.”

Crypto lender BlockFi also slashed jobs as the impact of the market turmoil filters through to companies.

The crypto sell-off comes as investors broadly shunned risky assets against a backdrop of fears over a potential global recession as major central banks around the world hike interest rates to tame inflation.

Policymakers at the U.S. Federal Reserve are now contemplating the idea of a 75-basis-point rate increase later this week, according to CNBC’s Steve Liesman. That’s bigger than the 50-basis-point hike many traders had come to expect. The Wall Street Journal reported the story first.

Rising rates tend to make future earnings for growth assets look less attractive.

Bitcoin has fallen nearly 70% from its all-time high in November 2021.
