⚠ The Lowest Margin of the FourLow threat

Bank of America (BAC) — threat to the moat

Wealth management keeps under nineteen cents of each revenue dollar, the least of Bank of America's four businesses.

Global Wealth & Investment Management keeps less of each dollar of revenue than Bank of America's other businesses. Its net income was about 18.8% of revenue in 2025, against about 28.0% for Consumer Banking, 32.3% for Global Banking and 25.4% for Global Markets1.

Advisers take the margin.

The likely reason is people. Wealth management is delivered largely by advisers, and people are the bank's largest cost: compensation and benefits expense was $42,346 million in 2025 across the whole company2.

A low margin is not a weak moat, but it limits how much the wealth business can contribute to closing the return gap with JPMorgan.

Even at the lowest margin the segment returns well on the capital it uses. Its return on allocated capital was 26% in the second quarter of 20263, because a wealth business needs little capital; the low margin limits profit per dollar of revenue, not return per dollar of equity.

The segment's pretax margin, 27% in the second quarter of 20264, is the figure to watch. A rise above 30% would mean the business was scaling; a fall would say adviser pay was taking the growth.
