Overview

Signature Bank was an American full-service commercial bank headquartered in New York City and with 40 private client offices in the states of New York, Connecticut, California, Nevada, and North Carolina. In addition to banking products, specialty national businesses provided services specific to industries such as commercial real estate, private equity, mortgage servicing, and venture banking; subsidiaries of the bank provided equipment financing and investment services.

At the end of 2022, the bank had total assets of US$110.4 billion and deposits of $82.6 billion; as of 2021, it had loans of $65.25 billion.

Signature Bank was founded in 2001 by former executives and employees of Republic National Bank of New York after its purchase by HSBC. It focused on wealthy clients and built personal relationships with them. For most of its history, it had offices only in the New York City area. In the late 2010s, it began to expand its services and geographic reach, though it was most noted for its 2018 decision to open itself to the cryptocurrency industry. By 2021, cryptocurrency businesses represented 30 percent of its deposits.

Banking officials in the state of New York closed the bank on March 12, 2023, two days after the failure of Silicon Valley Bank (SVB). After SVB failed and in light of the closure of the cryptocurrency-friendly Silvergate Bank earlier in the week, nervous customers withdrew more than $10 billion in deposits. It was the third-largest bank failure in U.S. history. Two days after Signature was closed, it became known that the bank was being investigated by the United States Department of Justice concerning its failure to properly scrutinize clients' activities for signs of money laundering.

At the time of its closure by state banking officials, the bank was rated as the fourth U.S. bank by uninsured banking deposits, with 89.3 percent of deposits being uninsured; internal reviews by the Federal Deposit Insurance Corporation (FDIC) and New York state regulators noted that Signature's risk control and corporate governance had not grown commensurate with an increase in deposits in the late 2010s and early 2020s.

Establishment and expansion

Signature Bank opened on May 1, 2001. It was founded by Joseph J. DePaolo, the bank's president and chief executive officer; Scott A. Shay, chairman of the board; and John Tamberlane, vice chairman and director. DePaolo and Tamberlane had left Republic National Bank of New York after it was purchased by HSBC the year prior.

Six branches were opened simultaneously across the New York City area, with the goal to cater to wealthy clients and middle-market business managers with $250,000 in assets: DePaolo described the target audience as "the guy who started his business in Brooklyn and is now worth $20 million". The bank was a subsidiary of Bank Hapoalim of Israel, which provided over US$60 million in initial capital. Among its first employees were 65 former Republic Bank employees, who left en masse on April 27, days before Signature opened its branches.

The bank quickly grew to $950 million in assets by February 2003, ranking in the top five percent of US commercial banks just 20 months after being founded and beginning to turn a profit. It also made relatively few loans: adopting a strategy once used by Republic Bank, it put its assets in instruments with lower yields. This led to a net interest margin of 2.8 percent, lower than many comparable banks.

The bank completed its initial public offering in March 2004 and began trading on the NASDAQ under the symbol SBNY. While remaining solely focused on the New York metropolitan area, Signature continued to rapidly grow, becoming one of the fastest-growing public companies in New York and one of the fastest-growing public banks for loan growth. It made a practice of hiring bankers—and luring their clients—from recently merged banks; it emphasized personal relationships so thoroughly that it did not advertise and its bank branches did not have street signs.

CEO DePaolo refused to decorate his office with art, finding it a sign of complacency, and usually ate a deli lunch at his desk. After the 2008 financial crisis, Signature's style of relationship banking led to years of double-digit increases in loans and deposits. From 2004 to 2014, its stock price rose 650 percent, a return 10 times the S&P 500 and double Silicon Valley Bank's parent, SVB Financial Group, the next highest-performing institution; a 2014 article in Crain's New York Business hailed Signature as "New York's most successful bank".

Beginning in 2007, it expanded into other areas of business, starting with the launch of a multifamily lending unit. The bank expanded into equipment finance in 2012 through its Signature Financial unit. Additionally, Signature cultivated a major business in servicing the New York area's law firms. An increase in loan activity offset its traditional reliance on mortgage-backed securities; its large capital cushion helped it to protect the many depositors whose accounts were larger than the Federal Deposit Insurance Corporation (FDIC)-insured $250,000.

General services

Signature Bank offered business and personal banking products and services with a focus on lending and deposits. The bank utilized a team model, paying its bankers on an "eat-what-you-kill" basis reminiscent of brokerage firms. In 2015, nearly 150 senior bankers reported directly to DePaolo; some made more than the CEO. It cultivated a reputation of being loyal to its clients, which in turn incentivized them to conduct further banking business with Signature.

Irv Gotti became a loyal Signature customer after it allowed him to use its services while on trial for federal money laundering charges in 2005; even though he had not been found guilty, other banks refused to let him maintain accounts. Among the company's nine national businesses in 2022 were commercial real estate lending, fund banking for private equity investors, venture banking for the technology industry, specialized mortgage banking, and corporate mortgage finance.

The fund banking business in particular had been a source of rapid growth; four years after being created, the fund banking portfolio had become Signature's largest asset, representing 41 percent of the bank's loan portfolio at the end of 2021.

In addition to banking products, two Signature subsidiaries provided additional services: Signature Securities Group Corporation, an investment advisory firm, and Signature Financial LLC, an equipment financing and leasing division.

On February 20, 2023, DePaolo, the bank's only CEO in its nearly 22-year history, announced his departure effective March 1—unrelated to the crash of the cryptocurrency bubble—to become a senior adviser; chief operating officer Eric Howell was to replace DePaolo as CEO at a later date. A later analysis by the Wall Street Journal found that DePaolo, Howell, and Shay had sold significant amounts of their Signature stock during the stock's cryptocurrency-fueled price surge in 2021, which eluded attention because the bank filed its insider trading reports with the FDIC, not the SEC, unusual for institutions of Signature's size.

Only one other S&P 500 member, First Republic Bank, did not file insider trading reports at the SEC. Additionally, some of the reports it did file were mischaracterized.

Cryptocurrency

The core of its cryptocurrency business was Signet, a payment network opened in 2019 for approved clients that allowed the real-time gross settlement of fund transfers through the blockchain without third parties or transaction fees, similar to Ripple. By the conclusion of 2020, Signature Bank had 740 clients using Signet. In its 2022 annual report, the bank cited the use of Signet by payroll processing and logistics clients in addition to digital asset banking.

In analyzing the bank's failure, the FDIC report also highlighted the lack of awareness by Signature management that its cryptocurrency activities could cause risk to more traditional customers of the bank.

Controversies

On July 13, 2018, The New York Times printed a full-length article on Signature Bank being the "go-to bank" to Donald Trump and the Trump family. The bank helped finance Trump's Florida golf course. Trump's daughter Ivanka Trump served on Signature Bank's board of directors between 2011 and 2013, before stepping down on April 24, 2013. Throughout most of the 2010s, the bank provided loans to people connected with the Trump Organization, while Ivanka Trump sat on its board of directors.

On January 11, 2021—in the aftermath of the January 6 United States Capitol attack—the bank closed two of Trump's personal accounts containing $5.3 million and called for him to resign from office, citing "the best interests of our nation and the American people".

Signature Bank provided financial support for re-election races to a number of United States senators for their support of the Economic Growth, Regulatory Relief, and Consumer Protection Act, according to Federal Election Commission data tallied by OpenSecrets. This bill eased regulations that had been imposed by the Dodd–Frank Wall Street Reform and Consumer Protection Act after the 2008 financial crisis, raising the threshold to $250 billion from $50 billion under which banks are deemed too big to fail, exempting Signature Bank from post-crisis oversight rules.

"We find it ridiculous and unacceptable that by virtue of … growing one day past $50 billion, we will be burdened with rules intended for the mega 'too big to fail' banks," Scott Shay, chairman of Signature, said. Barney Frank, both a former U.S. congressman (1981–2013) and a member of Signature Bank's board of directors (2015–2023), had voted in favor of raising the Dodd–Frank threshold. He went on record in 2018 stating: "My being on the board has not changed my position on this at all. These efforts began well before I began at Signature Bank."

In 2019, the bank was the center of several protests due to mistreatment of tenants by landlords who receive loans from the bank. Signature was one of the largest multifamily lenders in the New York metropolitan area; in 2019, it had $16 billion in loans in this sector, second only to New York Community Bank.

Despite these accusations, the Association for Neighborhood & Housing Development (ANHD) applauded the bank's commitment to responsible lending practices as it pertained to low- and middle income-tenants; the year before, under pressure from the ANHD and others, the bank had changed its policy to underwrite loans at current rents instead of market rates.
