• Margin loan balances at Charles Schwab nearly doubled in May 2026, signaling a surge in leveraged trading.
  • Client trading hit a record, while sweep cash rose 20% and total client assets climbed 27%.
  • Analysts project ~30% EPS growth, which may be conservative given current trends.

A Leveraged Surge

Charles Schwab Corp.'s May 2026 activity report reveals a dramatic increase in client leverage, with margin loan balances nearly doubling from the prior year, according to people familiar with the matter. The data, analyzed by William Blair, shows record client trading volumes and a 20% rise in sweep cash, while total client assets expanded 27%. The figures underscore stronger spread income and bolster bullish earnings momentum.

“The magnitude of the margin growth is striking, even for a firm that has seen elevated trading activity,” said an analyst who covers the brokerage space, speaking on condition of anonymity. Schwab’s disclosures highlight that clients are increasingly using borrowed funds to amplify their market bets, a trend that has been building over the past year.

The surge in leveraged activity comes as Schwab continues to expand its trading capabilities and maintain high client engagement. Sweep cash balances, which include uninvested client funds, rose 20% year-over-year, providing a stable base for the firm’s net interest income. Combined with record trading volumes, the data suggests that Schwab’s revenue mix is tilting toward spread income and transaction-based fees.

Implications for Earnings

The strong May metrics support analyst expectations for robust earnings growth. Multiple research notes have projected earnings per share growth of around 30% for the upcoming quarter, but some analysts now view this as conservative. “Given the trajectory of margin balances and trading volumes, there is upside risk to estimates,” noted a market strategist at a major investment bank.

Schwab’s stock has responded favorably, though the firm has not yet issued formal guidance. A spokesperson for Schwab declined to comment, citing the quiet period ahead of earnings.

Looking Ahead

While the near-term outlook appears bright, some observers caution that leverage-driven activity can reverse quickly if market volatility declines or interest rates rise further. The durability of client engagement will be key to sustaining the current momentum. For now, Schwab’s May data paints a picture of a retail brokerage boom fueled by aggressive risk-taking.
