The Resurgence of US Banks: A New Era of Growth and Deregulation
America’s largest banks are experiencing a remarkable upswing, fueled by a confluence of factors including regulatory shifts and a revitalized investment banking landscape. In 2025 alone, the six biggest US banks – JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs, and Morgan Stanley – collectively added $600 billion to their market value, reaching a combined $2.37 trillion. This surge dramatically outpaces their European counterparts, whose six largest banks total just $1 trillion in market capitalization.
The Deregulation Dividend: Unlocking Potential
For years following the 2008 financial crisis, stringent regulations weighed heavily on the US banking sector, dampening investor enthusiasm. However, the current administration’s push to roll back many of these rules is proving to be a significant catalyst for growth. Changes include allowing higher leverage ratios, overhauling stress tests, and rescinding guidance on riskier loans. “You cannot underestimate how important this regulatory change has been to the stock prices,” notes RBC banking analyst Gerard Cassidy. The easing of capital requirements allows banks to deploy more funds into lending and investment activities, boosting profitability.
This isn’t simply about loosening restrictions; it’s about recognizing the banks’ already robust capital positions. As Cassidy points out, banks proactively built up capital reserves in anticipation of stricter regulations, leaving them well-positioned to absorb potential losses while still capitalizing on new opportunities.
Investment Banking Rebound and Trading Boom
Beyond deregulation, a strong recovery in investment banking is driving significant gains. Goldman Sachs, for example, has seen its shares climb nearly 60% in 2025, reaching record highs. This is directly linked to a resurgence in both equities and fixed-income trading, with industry-wide revenues projected to surpass previous peaks this year – $92 billion from equities and $163 billion from fixed income, according to Crisil Coalition Greenwich.
The boom in trading activity reflects broader market dynamics, including increased volatility and a renewed appetite for risk. Banks are adept at capitalizing on these conditions, generating substantial revenue from facilitating transactions and providing advisory services.
Citi’s Transformation: A Case Study in Success
Citigroup’s impressive performance – a 70% increase in share value in 2025 – serves as a compelling case study. Years of strategic efforts to simplify the bank’s structure and cut costs are finally bearing fruit. This month, Citi’s market value exceeded the sum of its parts for the first time since 2018, signaling a significant turning point for the institution. This demonstrates that internal restructuring, combined with favorable external conditions, can unlock substantial value.
Navigating the Risks: A Balanced Perspective
While the outlook for US banks appears overwhelmingly positive, some voices caution against complacency. Democratic Senator Elizabeth Warren has expressed concerns about the potential consequences of deregulation, and analysts acknowledge the possibility of increased risk-taking. However, HSBC’s Saul Martinez believes that, for now, bank balance sheets remain healthy enough to absorb additional risk. “It’s a risk that may come up down the line,” Martinez says, “But given how little bank balance sheets have grown, there’s the sense that there is room to take more risk.”
The key will be striking a balance between fostering growth and maintaining financial stability. Regulators will need to carefully monitor bank activities and be prepared to intervene if necessary to prevent excessive risk-taking.
Basel III Endgame: A Less Onerous Future?
The anticipated implementation of the Basel III Endgame global capital rules is also expected to be less restrictive than initially proposed. Banks have already bolstered their capital reserves in preparation for stricter requirements, meaning the final rules are likely to have a less significant impact on their financial performance. This provides further reassurance to investors and allows banks to focus on deploying capital for growth.
Did you know? The combined market capitalization of the six largest US banks is now greater than the GDP of many countries.
Looking Ahead: Trends to Watch
Several key trends are poised to shape the future of the US banking sector:
- Fintech Integration: Banks will continue to invest in and partner with fintech companies to enhance their digital offerings and improve customer experience.
- Sustainable Finance: Growing demand for environmentally and socially responsible investments will drive banks to prioritize sustainable lending and investment practices.
- Artificial Intelligence (AI): AI will play an increasingly important role in areas such as fraud detection, risk management, and customer service.
- Digital Currencies: Banks will explore the potential of central bank digital currencies (CBDCs) and stablecoins, potentially reshaping the payments landscape.
