About Signature Bank
Signature Bank was a New York-based full-service commercial bank that provided financial services to privately owned businesses, institutional investors, and high-net-worth individuals. Founded in 2001, the bank became widely recognized in both traditional finance and the digital asset industry for its relationship-driven banking model and its early support for blockchain and cryptocurrency companies. The institution gained particular attention for launching one of the first blockchain-based digital payment systems operated by a U.S. bank.
Overview
Signature Bank® (NASDAQ: SBNY) operated as a full-service commercial bank headquartered in New York. The bank maintained private client offices throughout the New York metropolitan area as well as locations in Connecticut, North Carolina, and California. Its banking model focused on serving the financial needs of privately owned businesses, their owners, and senior executives, a segment that often found limited attention from larger financial institutions.
The bank combined traditional commercial banking services with technology-driven financial infrastructure, particularly in digital payments and blockchain-based financial networks. This approach helped the institution attract a wide range of clients across industries including real estate, professional services, private equity, and cryptocurrency businesses.
History and Background
Signature Bank commenced operations in May 2001 with the goal of delivering a relationship-focused banking experience. The institution was founded by a group of banking professionals led by Joseph J. DePaolo, who served as the bank’s chief executive officer. From its inception, the bank emphasized dedicated client service teams and customized financial solutions rather than a standardized retail banking model.
Over the following two decades, Signature Bank expanded rapidly, building a reputation for providing financial services to businesses that required flexible banking relationships. The bank also became one of the earliest U.S. financial institutions to actively serve companies operating in the cryptocurrency and blockchain sectors.
By the end of 2022, Signature Bank reported approximately $110.36 billion in assets and $88.59 billion in deposits. The institution ranked 19th on S&P Global’s list of the largest banks in the United States based on deposits as of the end of 2021.

Technology and Features
Signature Bank was the first FDIC-insured bank to launch a blockchain-based digital payments platform. Its proprietary payment network, Signet™, allowed commercial clients to move U.S. dollars between approved accounts in real time. The platform operated continuously, enabling payments 24 hours a day, seven days a week, and 365 days a year.
Signet was also the first blockchain-based banking solution approved for use by the New York State Department of Financial Services. The network was used by institutional clients to facilitate faster settlement of payments, particularly within digital asset markets where real-time liquidity and transfers are often required.
Use Cases and Market Position
Signature Bank served a diverse client base across traditional and emerging sectors. The bank’s services were commonly used for:
- Commercial lending and banking for privately owned businesses
- Financial services for real estate investors and developers
- Banking infrastructure for cryptocurrency exchanges and blockchain firms
- Real-time settlement of institutional payments through the Signet network
- Investment and brokerage services through affiliated subsidiaries
Within the digital asset ecosystem, Signature Bank was considered one of the key banking partners for cryptocurrency companies in the United States. Its blockchain payment infrastructure and willingness to serve digital asset clients differentiated it from many traditional financial institutions.
Regulatory Events and Closure
In March 2023, Signature Bank was closed by the New York State Department of Financial Services after experiencing significant deposit withdrawals during a period of instability in the U.S. banking sector. The closure occurred shortly after the failure of Silicon Valley Bank and during heightened scrutiny of banks with exposure to cryptocurrency clients.
The Federal Deposit Insurance Corporation was appointed as receiver, and certain assets and deposits were subsequently transferred to other institutions. The shutdown marked one of the largest bank failures in U.S. history and had significant implications for the cryptocurrency industry, which lost one of its primary banking partners.
Risks and Considerations
The collapse of Signature Bank highlighted the challenges faced by financial institutions operating at the intersection of traditional banking and emerging digital asset markets. Concentrated deposit bases, liquidity pressures, and regulatory scrutiny can affect banks serving rapidly evolving industries. The event also underscored the importance of risk management, regulatory oversight, and diversification in the modern financial system.
