Bank charter applications in the U.S. have surged to their highest level in five years, largely driven by fintech companies. Neobanks like Nubank, payment platforms such as Checkout.com, stablecoin issuers like Circle, and crypto exchanges like Coinbase are among the applicants. The article explores how these charters can enhance the value of fintechs and the changing landscape of banking since the financial crisis. After a period of fintechs partnering with regional banks to sidestep regulatory burdens, a shift in profitability and regulatory attitudes is prompting many to seek their own charters. The financial environment is more favorable for banks now, with net income rising to $70 billion quarterly in 2025 from $40 billion in 2015, thanks to increased interest rates. Fintechs are also generating significant revenue from interest, with companies like Revolut and Robinhood reporting 25% and over 30% of their revenue from this source, respectively. As fintechs achieve a critical mass of revenue from interest, the rationale for relying on partner banks diminishes. The article highlights a supportive regulatory climate, with agencies like the OCC signaling openness to charter applications, which could lead to faster approvals. Different types of banking charters are available, each with its own advantages and limitations. National Bank charters, like those applied for by NuBank, offer access to the federal banking system but come with strict capital requirements. Trust Bank charters, favored by firms such as Circle and Coinbase, enable limited activities like custody and payments while providing access to federal payment systems. Industrial Loan Company charters appeal to large corporations like Ford, allowing them to operate banks but limiting their activities. The recent Genius Act also incentivizes the issuance of stablecoins, further driving interest in Trust Bank applications.
