HSBC Q3 2026 Earnings Preview: Is the $46bn NII Guide Too Low?

HSBCHSBCHSBC Holdings plc$91.89-0.92% Valuation Verdict Speculative Upside Explore complete valuation & metrics: HSBC Holdings plc ProfileRun Full Report (NYSE:HSBC, LSE:HSBA) had a very good first half of 2026, but the stock has been sliding anyway. The ADR opened at ~$93 on October 20. That’s ~14% below its 52-week high of $107.92 and below the 50-day average of ~$101. Q3 results are due on October 27, and the UK Budget follows a day later.

My view: earnings aren’t the problem. The second-quarter numbers suggest management’s banking NII guide is conservative, and I expect Q3 to show that again. What the market really wants to know is how much capital HSBC will hand back. On that question, Q3 has less room to surprise than it did a year ago.

What management promised in August

At the interim results on August 4 (full detail in the Interim Report 6-K), HSBC changed one guidance line and kept the rest:

• Banking NII (net interest income from lending and deposits, excluding the trading book) for FY26: raised to “at least $46bn,” from “around $46bn.”
• Costs: ~1% growth in 2026 on a target basis. That’s maintained, but management warned it could drift up if performance pay rises.
• Credit losses (ECL): ~45bps of average loans in 2026, with 30–40bps the medium-term planning range.
• Returns: RoTE (return on tangible equity) of 17% or better excluding notable items in each of 2026–2028. Revenue should grow every year, reaching 5% growth in 2028.
• Capital: CET1 (the core capital ratio) in a 14%–14.5% range, with a 50% dividend payout.

The first half beat that plan comfortably. Reported pre-tax profit rose 23% y/y to $19.5bn. RoTE excluding notable items reached 19.1%, more than two points above the floor. On the analyst call, CFO Pam Kaur said Q2 annualised RoTE was 19.5%. Q2 banking NII was $11.6bn, up $0.8bn y/y.

The NII math already points higher

Q1 and Q2 together come to ~$22.8–22.9bn of banking NII. To reach “at least $46bn,” HSBC needs ~$23.1bn in the second half, or ~$11.55bn a quarter. That’s slightly below the Q2 run rate of $11.6bn.

Put simply, management’s guidance assumes the business stays flat or goes backwards. Kaur said as much on the call:

“with the run rate you could pretty much get to a larger number.”

She cited two supports. About $50bn of structural hedge assets (bonds the bank buys to lock in deposit income) yielding ~2.8% will be reinvested in the second half. Loans also grew $55bn (6%) in H1. The guide also contains a buffer for HIBOR (Hong Kong’s interbank rate) and for FX, since a weaker pound shrinks NII when it’s reported in dollars.

What I expect: Q3 banking NII at or slightly above $11.6bn, and the full-year wording moved from “at least $46bn” to something above $46bn. If NII comes in under ~$11.5bn without a clear FX or HIBOR explanation, I’d read that as the first sign that the hedge tailwind is weaker than management said.

There’s one caveat. Kaur said about half of Q2’s $42bn rise in CIB (corporate and institutional banking) deposits was “large and short term.” I’ll check whether those balances left in Q3 and how much NII left with them.

A soft comparison flatters the headline

Last year’s Q3 was messy. The 3Q25 release showed reported pre-tax profit of $7.3bn, down 14% y/y. That included $1.4bn of legal provisions, $1.1bn of which related to a Madoff-linked claim in Luxembourg. Excluding notable items, PBT was $9.1bn and RoTE was 16.4%.

That makes this year’s reported growth easy to inflate. I’ll judge the quarter on underlying PBT against the ~$9.1bn base and on RoTE excluding notable items. A reading above ~18% keeps the H1 trend intact. If underlying PBT growth fades to low single digits, the “starting point will be higher” story for 2027 gets weaker.

Costs and credit: two lines to watch

Costs. Target-basis costs grew 2% in H1, against a full-year guide of ~1%. As a rough approximation (it assumes the two halves are about the same size), the second half needs close to 0% growth y/y. CEO Georges Elhedery raised the simplification savings target from $1.5bn to $2bn, to be actioned by year-end. He also said the bank would “certainly consider” paying staff more in variable compensation for strong results. Kaur put last year’s variable pay at $3.9bn, or 11–12% of costs. So a cost miss caused by higher bonuses is more likely than one caused by weak discipline. I’d still want the 2026 guide repeated without new caveats.

Credit. H1 ECL ran at 47bps annualised and Q2 at 41bps. That implies ~43bps in the second half to land at ~45bps. Kaur pointed to $0.2bn of Stage 3 charges (loans already in default) in Hong Kong commercial real estate. She said the market was “stabilising,” with East Kowloon office vacancy still around 20%. She also flagged “small pockets of mid-market credit pressure” in the UK and Asia. The $300m Middle East reserve booked in Q1 stays in place until two clear quarters of stability. If Q3 is the first of those quarters, a release is possible later, but I wouldn’t count on it in this print.

What’s happened since August

Most of the big portfolio moves were announced just before the interim results, and none has closed:

• Singapore life insurance sale to Allianz: ~$1.8bn estimated pre-tax gain, expected in 1H27. SCMP reports a CET1 lift of up to ~15bps.
• Australian home and personal loans ($25.3bn of assets) to a Blackstone affiliate: immaterial loss, expected in 1H27.
• Egypt retail banking to Emirates NBD: ~$0.3bn gain, expected in 2H27.

Since the results, HSBC has paid its second interim dividend ($0.10 per share, or ~$1.72bn) and has been running the up-to-$1bn buyback, which is due to finish by the Q3 release. The stock fell on the day that buyback was announced. SCMP reported the market had expected $1.5–2bn.

The real swing factor: capital return

At 14.1% at the end of June, CET1 is near the bottom of the 14%–14.5% range. The Hang Seng Bank privatisation cost $13.7bn and used up much of the buffer. Elhedery set the order of priorities on the call: dividends first, then organic growth, then buybacks with whatever is left. Kaur said buyback decisions will be made “quarterly.”

The math is tight. In H1, HSBC generated ~100bps of capital. About 50bps went to dividend accruals and ~30bps to balance-sheet growth. That leaves ~20bps a half before any buyback. Loans are growing fast, and the Singapore gain doesn’t arrive until 2027. So my base case is another buyback of around $1bn, not a step-up. If HSBC announces more than $1bn, I’d treat that as the real upside surprise of the quarter. A pause would hurt.

Risks, ranked

1. UK tax policy. The Budget lands on October 28. Reports suggest the bank corporation-tax surcharge, cut to 3% in 2023, could go back up to 8%. HSBC earns most of its profit in Asia, so the direct hit is smaller than for domestic UK lenders. Still, management will probably face questions on it the day before.
2. Rates and HIBOR. NII is the biggest driver of earnings. Faster rate cuts, or another HIBOR slump like the one that hit Hong Kong deposit margins in 2025, would cut the cushion within the guide.
3. Credit drift. Hong Kong CRE and UK mid-market stress have been contained so far. If Q3 ECL comes in above ~50bps, the 45bps guide would be at risk.
4. Cost slippage from pay. This one is minor and self-inflicted, but it would matter if revenue softens at the same time.

What management must clarify

• Whether “at least $46bn” moves higher, and how much of Q2’s short-term CIB deposit growth has left.
• Whether the ~1% cost guide holds once any variable-pay increase is included.
• The size and timing of the next buyback, and the CET1 level the Board will actually run at.
• Wealth momentum. Q2 net new money was $25bn ($22bn from Asia), and wealth fees grew 18% in H1. I’d want both rates to hold.

My take

HSBC’s operating engine looks stronger than its share price suggests. The NII guide looks beatable, credit is on plan, and returns are running above target. The weak spot is capital: after the Hang Seng deal, buybacks no longer cover for everything else. A clean beat with another ~$1bn buyback probably keeps the stock range-bound. A higher NII guide combined with a larger buyback is what could close the gap to the 52-week high.

I’ll be watching two lines on October 27: the full-year banking NII guidance and the buyback figure. If the buyback disappoints again, I’d wait for the Budget to pass before adding.
