Chain Bridge Bank, National Association (N.A.) is a United States nationally chartered bank headquartered in McLean, Virginia. Established in 2007 by former Illinois Senator Peter Fitzgerald, the bank serves trade associations, think tanks, lobbying firms, political committees, nonprofit organizations, other businesses, and individuals nationwide.

Chain Bridge was founded in 2007 by Peter Fitzgerald, two years after he was succeeded in the Senate by Barack Obama. The bank was started and capitalized, in part, with family wealth. Fitzgerald's father, Gerald F. Fitzgerald, previously chaired Chicago's Suburban Bancorp, which was sold to Bank of Montreal in 1994 for $246 million. The extended Fitzgerald family has a long history in banking, having owned, co-owned, or managed approximately 57 commercial banks since the 1940s.

Shortly after opening, Chain Bridge Bank cancelled a bricks and mortar branching strategy and instead shifted to online technologies, such as remote deposit capture, in order to provide bank services nationwide. Thus, the bank only has one physical branch, which is location in McLean, 10 miles west of Washington, D.C.

During the 2008 financial crisis, Chain Bridge Bank attracted significant client deposits due to its lack of bad assets and debt. Peter Fitzgerald stated in September 2008, "We're drowning in liquidity because people are pulling money out from other places and depositing it with us." To accommodate clients' needs, particularly political campaigns requiring ready access to funds, the bank maintained high liquidity by investing deposits at the Federal Reserve or other liquid assets.

In 2012, the bank created a mortgage division specializing in customized lending, with a focus on jumbo loans.

The bank operates as a subsidiary of Chain Bridge Bancorp, Inc., a Delaware-chartered bank holding company. On October 7, 2024, the Company completed its initial public offering (“IPO”) by issuing 1.85 million shares of Class A common stock at a public offering price of $22 per share. The Company raised approximately $40.7 million in gross proceeds from its IPO. Shares trade on the New York Stock Exchange under the ticker symbol “CBNA."

Chain Bridge Bank's political profile expanded when Presidential candidate John McCain, Peter Fitzgerald's former Senate colleague, moved campaign funds to the bank in 2008. By 2011, the bank was "fast becoming the preferred bank of the Republican Party." In 2015, Bloomberg Businessweek headlined a story, "Where Candidates Stash Their Cash," describing the bank's dominance in banking Republican presidential campaigns and allied committees. As a result of these political connections, Bloomberg in 2015 called Chain Bridge Bank "The Most Important Bank in America."

Based on Fitzgerald's personal knowledge from his own experience in politics, the bank's services and policies are designed to meet the needs of political campaigns,. For example, the bank keeps its wire service open until 5 p.m., more than two hours later than most banks. Also, Chain Bridge bankers are familiar with Federal Election Committee regulations, and are required to keep their cell phone numbers on their business cards. As a result of this focus, Chain Bridge is uniquely dependent on its political business. "Its deposits tend to swell in election years and dissipate as soon as ballots are cast," noted the Richmond Times-Dispatch.

Chain Bridge Bank's clientele include a large number of Republican political campaigns, including John McCain, Mitt Romney, Jeb Bush, Rand Paul, Rick Perry, and Donald Trump. In addition, many super-PACs have also had accounts at Chain Bridge, such as ones representing Ben Carson, Carly Fiorina, Scott Walker, Bobby Jindal, Lindsey Graham, John Boehner, Sarah Palin, and the Republican National Committee.

Other Chain Bridge Republican affiliated clients have included several lobbying firms, the Susan B. Anthony List, the American Conservative Union (host of CPAC), and American Crossroads.

The Hawaii GOP told the FEC in February 2021 that it had a previously undisclosed bank account at Chain Bridge.

One Chain Bridge client, the Trump Victory Committee, was being investigated for campaign finance reporting discrepancies as of April 2021. The Trump Victory Committee made disbursements to state GOP committees, who in turn passed identical disbursements on to the RNC. This may have been an attempt to evade regulations limiting contributions that the RNC can receive.
