JPMorgan's profit grew year on year. What supported it?

By @engtmk · Research as of 19 October 2026

JPMorgan’s third-quarter profit rose 6% from a year earlier and fell 28% from the previous quarter. Both headlines describe the same result. The useful question is what supported the earnings, and how much of that support can continue.

This expands today’s eToro post and carries forward Friday’s growth-versus-cost question. For a bank, credit performance adds another layer to the sales and expense comparison.

Start with the comparison base

JPMorgan’s October 13 Q3 release reports net income of $15.305bn, versus $14.393bn in Q3 2025 and $21.155bn in Q2 2026. The exact figures imply growth of 6.3% year on year and a decline of 27.7% sequentially, before rounding.

Q2 had an unusually strong comparison base. Its earnings release identified Visa-related and other equity gains. The Q2 significant-items table puts these at $4.550bn and $1.026bn before tax, respectively, with $3.443bn and $776m after-tax contributions to net income.

Q3, meanwhile, included $658m of investment securities losses before tax, or $498m after tax, as shown in the Q3 presentation.

These items explain why the headline sequential comparison needs care. Subtracting a pretax gain from after-tax profit would mix incompatible numbers. Even a consistent adjustment for these named items would be only a partial bridge, rather than a complete measure of recurring earnings.

Revenue rose. Expenses rose faster.

The Q3 release’s firmwide table reports managed revenue of $50.907bn, up from $47.120bn, and noninterest expense of $27.295bn, up from $24.281bn. Managed revenue is a non-GAAP, fully taxable-equivalent measure.

The company’s rounded growth rates are 8% for revenue and 12% for expenses. The roughly four-percentage-point gap compares two growth rates; it is not a four-point margin decline.

There is a useful counterpoint in the arithmetic. Managed revenue less noninterest expense increased from $22.839bn to $23.612bn, about 3.4%. That calculated subtotal is before credit provisions and tax, not net income. Expenses can consume a larger share of revenue while the remaining dollar amount still grows.

The Q3 presentation attributes expense growth to compensation, brokerage and distribution fees, marketing and technology, among other factors. Some costs move with activity; some may support future growth. The investment test is whether that spending earns an adequate return over time.

Lower credit costs helped, with a different sequential picture

Provision for credit losses was $2.743bn versus $3.403bn a year earlier, a 19.4% decline calculated from the exact figures. It was also 9% above Q2’s $2.515bn. Those comparisons come from the Q3 release.

The Q3 presentation shows net charge-offs of about $2.2bn, versus $2.6bn a year earlier, and a $539m reserve build, versus $810m. The reserve still increased. The year-on-year benefit came from lower charge-offs and a smaller addition to reserves, rather than a reserve release.

That distinction matters for the next quarter. A lower provision supports current earnings, but repeating the benefit requires another favourable comparison. Credit losses and reserve estimates can change as borrower performance and the economic outlook develop.

Demand evidence is encouraging, but uneven

The Q3 presentation reports debit and credit card sales volume up 10% year on year. That is nominal spending, not inflation-adjusted consumption or a direct measure of household financial health.

It also shows Equity Markets revenue up 49% and Fixed Income Markets revenue down 4% year on year. The equity figure alone would give an incomplete picture of trading activity.

Together, the evidence supports a more specific reading than either headline profit comparison: customer activity held up in important areas, expenses grew faster than revenue, and lower year-on-year credit costs helped the bottom line. None of those observations establishes a fair share price.

The next earnings test

Three conditional scenarios frame what to watch. They are tests, not forecasts or assigned probabilities.

• Stronger earnings quality: revenue continues growing, expense growth moderates and credit performance remains sound. The key evidence would be a narrower revenue-expense growth gap alongside stable borrower outcomes.
• Growth with persistent cost pressure: spending and fee activity remain resilient, but expenses keep growing faster. Profit can still rise in dollars, although the return on that additional spending deserves closer scrutiny.
• A weaker credit cushion: charge-offs or reserve needs rise enough to offset operating progress. That would challenge reliance on lower credit costs as a continuing source of earnings growth.

At the next results, compare both the prior quarter and the prior year, separate significant items on a consistent tax basis, and inspect provisions alongside charge-offs and reserve changes. No unverified earnings date is needed to define that test.

For valuation, the missing step is a defensible view of sustainable earnings and capital needs, compared with the price paid. This article does not supply a current valuation model or a consensus benchmark, so it makes no cheapness or earnings-surprise claim.

Connecting the research

Friday’s TSMC article separated sales growth from profitability and valuation. The Costco sales test asked what stronger activity could establish before full earnings evidence arrived. JPMorgan adds the importance of the comparison base and credit costs to that same discipline.

Profit grew year on year. Understanding its supports is the next step.

Which matters more from here: sustained spending or stronger cost discipline?
