Here are 3 stocks that might be worth a closer look today:
Capital One Financial Corporation (COF)
Capital One stands out as one of the most direct plays on credit card profitability among large U.S. banks. Unlike peers that balance their loan portfolios across mortgages, corporate lending, and wealth management, Capital One generates a disproportionately high share of revenue from credit card interest income. This focus gives the company one of the highest net interest margins (NIMs) in the banking sector, consistently hovering in the 6–7% range, nearly double the consolidated NIMs of universal banks. The company’s strategic emphasis on mass-market and near-prime consumers allows it to capture wider spreads than traditional prime-focused lenders.
What makes Capital One especially compelling today is the Discover acquisition, which expands its card base and solidifies its position as the largest U.S. credit card lender by loan balances. This deal not only enhances its ability to generate high-margin interest income but also provides cost synergies through technology integration and expanded merchant networks. While elevated charge-offs are always a cyclical risk for consumer-heavy lenders, Capital One’s proven ability to price risk appropriately and sustain strong NIMs gives it a durable edge in this category.

Wells Fargo & Company (WFC)
Wells Fargo may not dominate the credit card space to the same extent as Capital One or American Express, but it remains a meaningful participant with a growing card portfolio. Historically, Wells Fargo’s credit card operations were underdeveloped relative to peers, partly due to regulatory constraints following its well-documented scandals. However, in recent years, the bank has reallocated capital into consumer lending, with cards emerging as a natural growth lever. This has begun to lift its interest income contribution, which is crucial given the bank’s overall consolidated NIM runs around 2.8–3%. Within its card book, however, the yields are far higher, making it a critical profit driver.
The story with Wells Fargo is about margin recovery and expansion potential. Management has emphasized digital platforms and partnerships, such as its co-branded cards with major retailers, as a way to scale balances and deepen customer relationships. Importantly, Wells Fargo’s strong deposit base gives it one of the lowest funding costs among large banks, which magnifies the spread it can earn on its credit card lending. While the overall card business is smaller compared to JPMorgan or Citi, its trajectory is upward, and in a higher-for-longer rate environment, cards represent one of the bank’s best paths to defending profitability through elevated net interest margins.

U.S. Bancorp (USB)
U.S. Bancorp is often viewed as a conservative regional bank, but its growing presence in the credit card market positions it squarely in the conversation around high-margin lending. Unlike its traditional commercial lending, where spreads are tighter, the card portfolio produces robust yields that meaningfully outpace the bank’s consolidated NIM of roughly 3%. With nearly one-third of its loan growth now tied to credit cards, USB has been intentionally tilting its balance sheet toward higher-return assets. This strategic shift has been a deliberate way to offset net interest income pressure from a slower mortgage and commercial lending environment.
What strengthens U.S. Bancorp’s ability to compete in this space is its distribution advantage through co-brand and regional partnerships, giving it efficient channels to acquire new cardholders. Its conservative credit culture has historically kept losses below peers, allowing the bank to maintain spreads without disproportionate risk. Investors often overlook USB in the credit card conversation because it lacks the scale of JPMorgan or Citi, but that underestimates its niche. A bank that uses cards as a selective high-margin growth engine. This balance between prudence and profitability makes USB a stealth but solid fit among the highest net interest margin credit card issuers.
