3 Bank Stocks Warren Buffett Is Heavily Invested In

Warren Buffett, despite retiring as Berkshire Hathaway's CEO at the end of 2025, maintains a significant investment portfolio heavily weighted in bank stocks. While Bank of America remains his largest bank holding at approximately $29 billion even after selling over 300 million shares this year, American Express represents a $32 billion stake and a decades-long investment; Buffett has also recently reinvested in Citigroup after previously reducing holdings. The article advises investors to consider risk tolerance, liquidity needs, and investment goals before investing in bank stocks.

Analysis

Warren Buffett, who is scheduled to retire as CEO of Berkshire Hathaway at the end of 2025 but will remain Chairman, continues to maintain significant exposure to the banking sector, a long-standing cornerstone of his investment philosophy predicated on sound banking practices. Recent portfolio adjustments in 2025 indicate a dynamic approach: Berkshire Hathaway's stake in Bank of America (BAC), valued at approximately $29 billion, was reduced by over 300 million shares, a 34% decrease from the end-of-2024 holding of over 1 billion shares, though it remains his largest bank investment. In contrast, American Express (AXP) continues to be a core long-term holding, with 151.6 million shares valued at around $32 billion, reflecting a multi-decade investment. Citigroup (C) has seen a more substantial reduction, with Berkshire's holdings decreasing from 55 million shares (valued at approximately $3 billion last year) to just under 15 million shares in 2025; this significant sell-off is notable given that Citigroup was previously a stock Buffett had reinvested in after an earlier divestment. These actions, including substantial sales in BAC and C, suggest a selective re-evaluation of specific bank holdings within the portfolio, even as the overarching belief in the sector persists.

Key Decisions for Investors

• Investors should consider the implications of Berkshire Hathaway's significant recent divestment in Bank of America (BAC) and Citigroup (C) shares, which may signal a revised outlook or strategic profit-taking on these specific institutions despite Buffett's general affinity for bank stocks.
• The continued substantial holding in American Express (AXP), a decades-long investment valued at approximately $32 billion, suggests enduring confidence in its business model and could warrant attention from investors seeking stable, long-term financial sector exposure.
• Given the recent selective selling within Berkshire's bank portfolio alongside the article's general counsel on risk assessment and diversification, investors should perform thorough due diligence on individual bank stocks, aligning choices with their personal financial goals and risk tolerance rather than solely replicating past high-profile holdings.
