USDC and SVB: The Digital Dollar Waiting for Monday

A bank failure inside a stablecoin's reserves

At 11:37 a.m. ET on Friday, March 10, 2023, Silicon Valley Bank was taken into receivership. The Federal Reserve's later reconstruction of the weekend records what preceded it: more than $40 billion of depositor withdrawals in a single day, a run fast enough that California's financial regulator closed the bank and handed it to the FDIC while the week was still ending.^[3][1]

The FDIC's Friday announcement drew a hard line between two classes of depositor. Insured depositors would have full access to their insured deposits no later than Monday morning, March 13. The uninsured would receive an advance dividend within the next week and receivership certificates for the rest — a claim on a legal process, not cash. As of December 31, 2022, the bank held approximately $209.0 billion in assets and about $175.4 billion in deposits. Circle's $3.3 billion at SVB sat on the uninsured side of the line.^[1][3]

The market did not wait for Circle to speak. Redemptions rose sharply after the 11:37 a.m. receivership announcement, and by the Fed researchers' reading they peaked shortly before Circle said anything publicly. At about 10 p.m. ET, the issuer confirmed what the outflows had already signaled: $3.3 billion of USDC's cash reserves remained at SVB, about 8% of total reserves, after transfers Circle initiated on Thursday failed to settle by the close of business Friday.^[3][2]

What one digital dollar promised

Circle's March 11 statement described a reserve that was, on paper, overwhelmingly conservative. USDC was collateralized 77%, or $32.4 billion, with U.S. Treasury bills maturing in three months or less, held in custody at BNY Mellon and managed by BlackRock, and 23%, or $9.7 billion, in cash across a variety of institutions, including $1 billion at Customers Bank and zero at Silvergate. The week before, Circle had moved $5.4 billion to BNY Mellon. The immediate problem was where part of the reserves sat, while the recovery value of the uninsured SVB deposit remained uncertain. The Thursday transfers out of SVB had not settled.^[2]

The disclosure also drew the distinction that would define the weekend. USDC could be used 24/7/365 on chain, but issuance and redemption were constrained by the working hours of the U.S. banking system, and liquidity operations would resume when banks opened Monday morning. A transfer between holders never touches the reserve. A redemption requires the issuer to pay real dollars out of a bank account. When the banks closed on Friday, the redemption door closed with them, and the only exit left was selling to other traders.^[2][3]

Circle paired the disclosure with a pledge. If SVB did not return 100% of deposits, Circle said it would "stand behind USDC and cover any shortfall using corporate resources, involving external capital if necessary." The Fed's researchers later judged that such reassurances may have helped shore up the price during the weekend but were not sufficient to restore the peg. Words could not settle a bank transfer.^[2][3]

Saturday priced the wait

With the redemption window shut, the secondary market became the price of impatience. At its trough, USDC traded at 86 cents to the dollar — a fourteen-cent discount on an instrument whose reserves were mostly short-dated Treasury bills. Hourly trading volume shot up to nearly $2 billion on March 11 as holders who could not redeem looked for anyone willing to take the other side.^[3][2]

The stress traveled through decentralized finance with mechanical indifference. MakerDAO's Peg Stability Module accepted USDC one-for-one against DAI under hard-coded smart contracts, guarded only by a 950 million USDC daily cap. The cap was swiftly reached — around 1 billion USDC was deposited into the facility on both March 10 and March 11 — dragging DAI's price toward USDC's even though DAI itself remained solvent and overcollateralized. The spillover reached smaller tokens: USDP fell to around 91 cents and GUSD to about 96 cents, while USDT and BUSD traded marginally above a dollar.^[3]

Maker's risk team responded on Saturday morning. A Risk Core Unit proposal, posted at 8:02 UTC on March 11, called for cutting the PSM-USDC-A daily mint capacity from 950 million DAI to 250 million DAI and raising the fee for swapping USDC into DAI from zero to 1 percent. Governance passed the changes in just over two hours — but the protocol's security delay meant they could only be executed on Monday, March 13, by which time, the Fed researchers note, most of the market turmoil was already resolved.^[4][3]

Sunday evening answered

The decisive break in the run came from Washington. At 6:15 p.m. ET on Sunday, March 12, Treasury Secretary Janet Yellen, Federal Reserve Chair Jerome Powell, and FDIC Chairman Martin Gruenberg announced that SVB depositors would have access to all of their money starting Monday. No losses would be borne by the taxpayer. Shareholders and certain unsecured debtholders would not be protected, and senior management was removed. Any cost to the Deposit Insurance Fund would be recovered through a special assessment on banks, and a similar systemic risk exception covered Signature Bank, closed the same day.^[5][3]

The Federal Reserve acted the same evening with the Bank Term Funding Program: loans of up to one year to banks and other eligible depository institutions pledging U.S. Treasuries, agency debt, and mortgage-backed securities valued at par, with up to $25 billion from the Exchange Stabilization Fund as backstop, eliminating the need to quickly sell such securities in times of stress. The liquidity program and the deposit guarantee were separate acts. It was the joint statement, not the funding program, that promised depositors they would be made whole.^[6][5]

Circle's response was published under a Boston dateline that Sunday evening. The $3.3 billion held at SVB, about 8% of the USDC total reserve, would be fully available when U.S. banks opened the next morning. No USDC cash reserves were held at Signature Bank, the second bank named in the government's action. USDC remained redeemable 1:1, and automated minting and redemption through new banking partners would go live that week.^[7][5]

Jeremy Allaire, Circle's co-founder and CEO, said the company treated trust, safety, and 1:1 redeemability as paramount even amid banking contagion in crypto markets.^[7]

Monday arrived

The FDIC completed the resolution it had started on Friday. On Monday, March 13, it transferred all deposits — insured and uninsured — and substantially all assets of the former Silicon Valley Bank to Silicon Valley Bridge Bank, N.A., a newly created, FDIC-operated bridge institution, and depositors had full access to their money beginning that morning. Tim Mayopoulos, a former president of Fannie Mae, was named CEO of the bridge bank.^[8]

USDC's price recovered sharply after the Sunday announcement and fully recovered once Circle began processing redemptions on Monday. By Wednesday, March 15, Circle said it had cleared substantially all of the minting and redemption backlog: since Monday morning it had redeemed $3.8 billion in USDC and minted $0.8 billion. The waiting had ended; the flows it set off had not.^[3]

The rebalancing outlasted the peg's return. The Fed researchers' data shows the cash Circle held in U.S. financial institutions fell from $11.5 billion on March 6 to $3.7 billion on March 31, despite the official intervention and Circle's public assurances. The SVB deposit became available in full, but Circle ended March with far less cash held at U.S. financial institutions.^[3]

What the weekend proved

When Fed researchers returned to the episode in a December 2025 FEDS Notes study, they framed it as evidence of two-way feedback between the traditional banking system and decentralized finance. A bank run moved a stablecoin. The stablecoin's plumbing moved another stablecoin. Their granular dataset placed the trough at 86 cents and showed redemptions peaking before Circle's own announcement — the run, in other words, did not wait for the issuer to describe it.^[3]

Their sharpest structural finding concerned the difference between a bank and a token. Suspending primary redemption cannot arrest a stablecoin run the way closing a bank can, because secondary markets trade continuously and there is no door to lock. Hard-coded facilities like the peg stability module became contagion channels rather than firewalls, pulling a solvent, overcollateralized DAI toward a discounted USDC.^[3]

A stablecoin needs more than assets on a balance sheet: holders must trust both their value and the issuer's ability to reach them. On March 10, 2023, about 8% of USDC's reserves sat in an uninsured bank deposit with uncertain recovery. Sunday's guarantee removed that loss risk; Monday's redemptions completed the return to the peg. The chain had kept moving throughout. The dollars had needed a bank and a public guarantee.^[3][2][5]
