* Signature Bank’s pivot to crypto deposits accelerated its growth but exposed it to unprecedented volatility and contagion risks, leading to its seizure by regulators in March 2023.
* Poor governance and inadequate liquidity management were the root causes, as the bank failed to align risk practices with its expanded complexity.
* The failure revealed flaws in liquidity risk models, showing that traditional assumptions underestimate the speed of digital-era deposit runs.
* Regulators now emphasize updated frameworks to incorporate technology, customer behaviour, and sectoral concentrations like crypto.
* For the crypto industry, the loss of banking partners could slow U.S. growth, forcing firms to seek alternatives or relocate offshore.
In March 2023, Signature Bank, a well-known commercial bank based in New York, failed in a big way. This shocked both the traditional banking industry and the cryptocurrency business. The bank was founded in 2001 and at first specialized in loans for commercial real estate and industry.
However, during the pandemic-era boom, it shifted its focus to higher-risk projects, including a big push into crypto-related services.
This change not only sped up its expansion, but it also showed serious problems with how it managed risk. This essay looks at how Signature Bank’s exposure to cryptocurrencies led to its downfall and changed the way banks think about risk. It stresses the necessity for stronger liquidity assumptions and governance in the age of digital finance.
Signature Bank’s Change in Strategy to Crypto
Signature Bank started to diversify its portfolio in 2018 because it was too dependent on commercial real estate loans, which were over the risk levels that U.S. regulators said were safe. At a financial industry conference in 2018, John Tamberlane, the bank’s vice chairman, said, “We don’t want the commercial real estate concentration that we currently have.”
To help with this, the bank started lending to cab drivers, heavy-equipment companies, private-equity investors for short periods of time, and, most importantly, a digital assets banking organization.
The bank’s acceptance of cryptocurrencies began with the development of Signet, a blockchain-based payment network in 2019. This platform lets commercial clients, including crypto businesses, make payments in real time 24 hours a day, seven days a week.
By January 2021, Signature had almost $10 billion in crypto deposits, making it a major participant in the space. Eric Howell, a bank official, said it was “the best player in that space.” By the end of 2022, deposits tied to digital assets made up around 20% of the bank’s total deposits. This helped the bank’s assets expand from $47 billion in 2018 to $110.4 billion.
But this diversity made things more dangerous in new ways. The bank’s plan depended on uninsured deposits from crypto customers, which were very concentrated and affected by changes in the market.
As the crypto industry went through a rough patch, with platforms like FTX going down in November 2022 (they were a client of Signature), regulatory attention grew. To protect themselves, the bank sold off $8 billion in crypto-related deposits in December 2022, but confidence was already starting to fall.
The Cascade that Led to Failure
In March 2023, a wider banking crisis caused a liquidity issue that led to the failure of Signature Bank. On March 8, Silvergate Bank closed its doors, and on March 10, Silicon Valley Bank failed. This caused panic and a huge amount of money to leave Signature Bank.
On March 12, the New York State Department of Financial Services took over the bank because it couldn’t give accurate information, which led to a loss of trust in its leadership.
Regulatory reviews found that bad management and weak risk controls were the main problems. The FDIC’s assessment said that the bank was trying to grow “quickly and without limits” without putting in place and keeping up with risk management techniques and controls that were suitable for the size, complexity, and risk profile of the organization.
In particular, Signature didn’t realize how risky it was to be involved with crypto, since many of its digital asset clients pulled out their money during a time of industry instability.
The run got worse because the bank relied too much on uninsured deposits, which made up more than 80% of all deposits. These funds turned out to be much less “sticky” than expected. Investigations also found possible problems with following anti-money laundering (AML) rules when it came to bitcoin clients.
Before the collapse, the FDIC was getting ready to issue a consent order for what looked like violations of sanctions and anti-money laundering (AML) rules. This shows how crypto exposure made regulatory and reputational risks worse.
Rethinking Banking Risk Models Post-Signature
The collapse of Signature Bank showed that typical banking risk models have big holes in them, especially when it comes to managing liquidity and making assumptions about how people will deposit money.
Before the collapse, models typically didn’t take into account how quickly and how much money would be withdrawn, especially in digital contexts where clients could move money immediately through platforms like Signet.
The New York Department of Financial Services’ internal study said that “the rapid collapse of Signature shows how important it is to rethink the assumptions used to model and manage liquidity risk.”
Depositors took out money at rates that were much higher than normal stress conditions. This led to requests for new frameworks that take into consideration technology-driven behaviours and the unique volatility of cryptocurrencies.
Since then, banks and regulators have pushed for better evaluations of liquidity risk. The FDIC’s Material Loss Review said that Signature’s wrong assumptions about deposit loyalty, especially from crypto clients, showed that uninsured, concentrated deposits need to be modelled more carefully.
This has caused bigger changes in the industry, such as stricter stress testing for mid-sized banks and more attention on sectoral concentrations like digital assets.
For example, the joint statement from U.S. regulators in January 2023 cautioned against the systemic dangers of crypto, which kept banks from getting into similar situations and made sure these risks were taken into account when calculating risk-weighted assets.
The European Central Bank reiterated these worries in Europe, saying that banks like Signature were at risk from crypto since they were growing so quickly. It also called on regulators to do a better job of finding links between traditional banking and riskier industries.
Overall, Signature’s case has led to a trend towards risk models that are more flexible and cognisant of technology and that put a lot of emphasis on planning for the unexpected and keeping an eye on things in real time.
Effects on the Crypto Industry
Signature’s failure hurt the U.S. crypto economy in more ways than just banking. As one of the few big banks that would work with crypto businesses, its failure caused a gap in important services like dollar deposits and fast transfers.
Taylor Johnson, who helped start PsyFi, said, “If there is no U.S. bank that will take deposits from a crypto client, the effects would be huge.” It would hurt a lot and make people and businesses in the U.S. do less with crypto.
John Lo, managing partner at Recharge Capital, said that smaller crypto businesses would be hit the hardest because major companies are switching to bigger banks and new initiatives are having trouble finding partners.
Ryan Selkis, one of the founders of Messari, tweeted that “crypto’s banking rails have been effectively shuttered in less than a week.” He saw this as an indication that crypto is not accepted in the U.S. This has caused several companies to move their operations overseas, which could hurt innovation in the US.
