From Monday, both individuals and organizations with money deposited with SVB will have access to all of their funds, according to the government.
In response to increasing pressure, regulators also shut down New York-based Signature Bank.
Later on Monday, President Joseph Biden will speak on the eventful weekend in the banking industry.
He pledged to "bring those responsible for this debacle completely accountable" in a statement.
SVB, which specialized in financing tech startups, was shut down by officials on Friday after they confiscated its assets. Since the 2008 financial crisis, it was the biggest failure of a US bank.
Depositors would be completely safeguarded, according to a statement from the US Treasury, Federal Reserve, and Federal Deposit Insurance Corporation (FDIC). The change wouldn't result in any losses for the taxpayer, it claimed.
To cover a loss on the sale of assets impacted by increasing interest rates, SVB was frantically trying to raise cash.
"The US banking system remains resilient and on a solid foundation, in large part due to reforms that were made after the financial crisis that ensured better safeguards for the banking industry," the authorities' joint statement said.
"Those reforms, combined with today's actions, demonstrate our commitment to take the necessary steps to ensure that depositors' savings remain safe."
These measures also apply to Signature Bank of New York, which is considered to be the most vulnerable institution behind SVB and took regulatory control on Sunday.
Regulators also introduced a new method for providing banks with access to emergency money as part of their efforts to regain confidence.
Banks will now find it simpler to borrow from the Federal Reserve in times of crisis, thanks to the announcement that it will provide help through a new Bank Term Financing Program.
SVB was regarded as an essential lender for start-up IT companies. Over half of the US venture-backed technology and healthcare companies that went public last year had it as their banking partner.
A media reporter in a social media post said, “I've been speaking to people with money stuck in SVB over the weekend."
One founder told me he had been constantly refreshing his online banking page, hoping it might work.
Another said he was confident the government would step in, but admitted he might have lost about 40% of the company's cash overnight.”
This statement, then, has been welcomed by depositors. But there are those who will raise eyebrows at this move.
SVB primarily banked Silicon Valley's finest tech start-ups and venture capitalists. Furthermore, those Silicon Valley elites frequently hold a libertarian political stance; their standard stance is that of a slow, overbearing government.
Opponents contend that it is ironic that the government has intervened to save the day. Some may question whether powerful tech companies have received preferential treatment, with capitalism being used when things go well and socialism being used when they don't.
While taxpayers won't be on the hook for this, the statement is carefully phrased to reflect that. Now that the action has been taken, Mr. Biden will need to defend it and reassure members of his own party that insuring depositors was the only option.
Authorities in Canada temporarily took over custody of the assets of the SVB branch there. The chief banking regulator declared that it planned to pursue long-term dominance.
In 1983, SVB was founded as a bank in California and has since experienced significant growth.
However, it came under strain as it became more difficult for start-ups to generate money through private fundraising or share sales as a result of increasing borrowing rates.
The effects of the crash have been felt widely in Silicon Valley as businesses wonder what it means for their financial situation.
Paul Ashworth, chief North America economist at Capital Economics, said the US authorities had "acted aggressively to prevent a contagion from developing".
"Rationally, this should be enough to stop any contagion from spreading and taking down more banks, which can happen in the blink of an eye in the digital age." "But contagion has always been more about irrational fear, so we would stress that there is no guarantee this will work," he added.
In the meantime, HSBC purchased SVB's British division.
The arrangement, which was hammered out with HSBC throughout the night to be completed before trading began on Monday, was said to have included no taxpayer money.
Consumers and companies who previously couldn't access their money will now be able to do so as usual.
