Wells Fargo Shows 2H 2026 NII and NIM Shaped by Deposits and Card Growth

Separating structural vs cyclical drivers of NII/NIM at Wells Fargo (WFC)

Below is how investors can disentangle structural vs cyclical forces behind net interest income (NII) and net interest margin (NIM) using Wells Fargo’s own commentary for the second half of 2026, including deposit cost expectations, whether an additional rate move is priced in, and how market activity vs card momentum can create (or relieve) secular NIM pressure beyond macro.

1) A framework: what’s “structural” vs “cyclical” in WFC’s discussion

Cyclical (macro/rate-driven) components

1. Short-end rates / repricing path: management explicitly talks about what is “baked in” for the second half via the market’s pricing of a short-rate increase. They also expect NIM volatility mainly around timing of rate moves rather than a sustained directional shock. ¹
2. Near-term deposit repricing (“deposit costs”): management’s near-term NIM path depends on whether deposit betas rise (i.e., interest-bearing deposits reprice higher), which is a cyclical component. ¹²

Structural (business-model / mix / optimization) components

1. Balance sheet mix: interest-bearing liability growth from growth initiatives: management says NIM is down largely because of growth in interest-bearing deposits and continued growth in markets business—i.e., mix/strategy rather than pure macro. ³
2. “Flywheel” effect management is pursuing: Charles “separate[s] out” NII from (a) the stable core and (b) growth businesses with “narrower margin NIM,” arguing this is an intentional tradeoff that can ultimately support NIM expansion through more noninterest-bearing deposits and stronger trading revenues. ⁴⁵
3. Card-account onboarding/promotion economics: the build-out of new credit card accounts is structurally dilutive in early years due to marketing/promotional/allowance upfronts and is expected to recover as vintages “season and earn.” ⁶⁷
4. Markets financing vs NIM/fee translation: management points out markets financing balances may be lower spread, but they claim they can be “getting paid” via trading revenue and share—so secular NIM outcomes depend on whether the deployed balance turns into trading/other revenue. ⁵⁴

2) Deposit costs in 2H: expected direction and what it implies for NIM

What management expects for deposit costs in the second half

• Wells Fargo indicates that it expects deposit cost to “move up a little” in the second half, tied to growth in interest-bearing deposits outpacing slower growth in noninterest-bearing deposits. ¹²
• The reason is not framed as customers changing pricing behavior due to rates; instead, it is tied to composition: faster growth in CIB/Corporate & Investment Bank and commercial bank deposits, which are “majority…interest bearing,” while consumer noninterest-bearing is relatively stable. ¹
• Management characterizes this deposit-cost rise as “fine and expected,” and even beneficial for profitability because it supports profitable customer relationships (even if NIM is pressured). ²

How to separate this from macro rate moves

• The deposit cost movement described above is a structural mix effect with cyclical repricing sitting underneath. Put differently: even if the short-rate path is stable, NIM can compress if the deposit base is structurally shifting toward interest-bearing growth. ¹²³
• Wells Fargo also asserts that “interest rates are currently not a significant factor in or out of this year” for certain deposit/noninterest dynamics; they instead emphasize the balance sheet and deposit growth strategy. ⁸

3) “Is a rate hike priced in” for 2H—and why management says it won’t matter much to full-year results

What’s “baked in”

• Management says the markets are pricing in “a little over a 1 increase” and that management will “see how that actually plays out,” but expects this to have “very little impact on the full year results” due to “timing.” ¹

Interpretive takeaway for investors

• This suggests management is not assuming a major sustained rate regime shift that would dominate NIM across the full year. ¹
• Instead, near-term NIM sensitivity is expected to be driven more by deposit mix and repricing, plus business mix changes, than by a single additional rate move. ¹²³

4) Expected NIM path in 2H: “small compression” in 3Q and stabilization in 4Q

• Wells Fargo expects “a little bit more NIM compression in the third quarter” followed by stabilization later. ²
• They reiterate: “a small decline potentially in the third quarter… and then we sort of stabilize from there.” ⁹
• They also explicitly say they do expect NIM to stabilize after you get through the third quarter. ¹⁰

What components management cites as helpful into stabilization

1. Moderation of markets balance sheet pace: they do not expect markets’ balance sheet to keep growing at the same pace; the “impact…over the last…few quarters” should moderate into the latter part of the year. ⁹
2. Benefits from earning asset growth and securities repricing: continued benefit from “growth in earning assets” and “repricing…across a large portion of the securities book.” ²
3. Portfolio growth support: they describe second half progress as growth in loans/securities, plus fixed asset turnover given rate conditions. ¹¹

5) Market activities vs card momentum: how each can push NIM differently (and what “secular pressure” could still mean)

A) Markets business: can be NIM dilutive short term, but management argues it can become NIM/returns accretive via trading

• On structural vs cyclical, management frames NIM pressure as coming from additional businesses to grow—including markets and treasury management—which carry “narrower margin NIM” and therefore bring down NIM in the short run. ⁴
• However, management argues that over time this should help them grow NIM by attracting more noninterest-bearing and generating stronger trading revenues (“flywheel effect”). ⁴
• They also emphasize a decision framework: if they don’t see payoff (e.g., higher trading revenues/returns), they can “pull back…or improve the NIM,” implying that NIM drag is not meant to be permanent or uncontrolled. ¹²
• In the quarter, they reported that markets total revenue grew 24% year over year and that “returns [are] starting to increase along with our market share,” which they use to support the idea that markets activity can translate into better outcomes beyond the immediate NIM hit. ³

How this affects “secular pressure beyond macro”:

• If the markets mix keeps growing but does not translate into sufficient trading/noninterest-bearing inflows, that would represent continuing structural NIM pressure even with stable macro rates. ⁴⁵
• Conversely, if client-by-client financing deployment continues to lead to more business/trading (“more share, higher trading revenues”), secular pressure could lessen because the mix shift is self-reversing over time. ⁵¹³

B) Credit cards: early-year economics are structurally NIM dilutive; recovery depends on vintage seasoning

• Wells Fargo explicitly characterizes card build as an “investment that pressures on profitability in the initial years,” with upfront costs tied to “marketing, promotional rates, onboarding, and allowance.” ⁷
• They state it takes approximately 2 to 3 years for vintages to “season and earn through these upfront costs.” ⁷
• On momentum timing, they discuss new credit card accounts being up sharply and ask how much drag those new accounts/promotions create and when back-end earning overwhelms the new-account drag. ⁶
• Management’s transcript indicates they view NIM pressure from these new cards as part of a structured ramp-to-profit model rather than an uncontrolled macro surprise. ⁷⁶

How this affects “secular pressure beyond macro”:

• Card-driven secular pressure would persist if the business expands faster than vintages can season (or if promotional economics remain costly longer than expected). ⁷
• If vintages from 2022–2024 are already “adding to profitability,” then the card initiative could move from secular drag toward secular support—meaning NIM could stabilize or even expand if the mix shift matures as planned. ⁷

6) A practical separation checklist investors can use (based on WFC commentary)

1. Rates priced in vs actual sensitivity

   • Use management’s statement that markets are pricing “a little over a 1 increase” and that timing implies “very little impact on the full year results” to discount the idea that 2H NIM is dominated by one incremental rate move. ¹

2. Deposit cost: composition first

   • Treat expected deposit cost “move up a little” as partly structural (interest-bearing deposit growth outpacing noninterest-bearing stability), not purely cyclical “customer dislike” of rates. ¹²

3. Markets NIM drag: watch for “flywheel” confirmation

   • If markets financing volumes rise but trading revenues/returns don’t follow, that’s structural NIM impairment; if they do, management argues the drag can reverse over time. ⁴⁵³

4. Card NIM: track vintage seasoning rather than account growth alone

   • Account growth can be NIM-dilutive early; the key secular question is whether “2 to 3 years” seasoning is progressing as vintages mature. ⁷

5. Intra-year shape: 3Q compression then stabilization

   • Since management expects small 3Q decline and stabilization thereafter, investors should distinguish one-quarter timing effects from lasting structural deterioration. ²⁹¹⁰

7) Bottom line answer to the question

• Deposit costs in 2H: Wells Fargo expects deposit costs to rise modestly in the second half (“move up a little”) primarily because interest-bearing deposits are growing faster than noninterest-bearing deposits, and management views this as expected given deposit/relationship strategy. ¹²
• Whether a rate hike is priced in: Management says markets are pricing “a little over a 1 increase,” but it should have very little impact on full-year results due to timing, implying investors shouldn’t over-attribute 2H NIM movement to a single incremental rate action. ¹
• Market activities vs card momentum on NIM and secular pressures:
  • Markets: Additional markets growth can be NIM dilutive short term because it increases mix of narrower-margin liabilities, but management argues a secular “flywheel” can support NIM expansion via future noninterest-bearing deposits and higher trading revenues; they also note they can unwind/pull back if payoff is not occurring. ⁴⁵¹²
  • Cards: Card expansion is structurally profit-pressuring in early years due to upfront costs, with vintages expected to season and earn through that pressure over 2–3 years; management suggests older vintages (2022–2024) are already adding to profitability, which would reduce the likelihood of indefinite secular NIM pressure from card growth. ⁷

Overall, Wells Fargo’s own framing supports a view that 2H NIM dynamics are more about deposit mix + business mix ramp effects (markets and cards) than about an incremental 2H rate move alone, with management expecting 3Q compression followed by stabilization as those mix effects and markets pace moderation play out. ¹²⁹¹⁰
