Wells Fargo Maintains 2026 NII Near $50B as Q2 Drivers Support Outlook

How Q2 2026 NII drivers supported keeping full-year 2026 NII at ~$50B while expecting Q3 NIM compression and Q4 stabilization

1) The guidance framing: hold full-year NII at $50B +/- while managing a short-term NIM dip

Wells Fargo maintained full-year 2026 net interest income guidance at $50 billion plus or minus. ¹
Management also explicitly expected modest NIM compression in Q3 followed by stabilization in Q4. ²

Key implication: the company’s plan was not to “hold NIM flat” quarter-to-quarter, but to offset a Q3 margin headwind with balance-sheet and markets financing-related NII support, so the full-year NII remains near $50B. ²¹

2) Loan balances: growth momentum supported maintaining NII despite NIM pressure

Management pointed to strong loan growth as a primary contributor to NII durability.

• Average loans increased 12% year over year in Q2 2026 (as described on the call). ³
• Looking to the back half, management expected Q4 average loan growth to be higher than the mid-single-digit increase assumed earlier in 2026 outlook. ³

Because NII mechanically depends on earning asset volumes, this loan momentum helps “carry” NII even if the margin (NIM) compresses temporarily. ³²

3) Interest-bearing deposits: strong growth deepened relationships and created a predictable—but manageable—cost impact

Management emphasized that Wells Fargo was successfully growing interest-bearing deposits, and that these higher balances were helpful for deepening customer relationships. ¹

They also gave the expected margin implication:

• Deposit growth was described as being a major contributor to NIM decline, specifically noting that the biggest driver of the decline in NIM in Q2 (and over the past year) was growth in interest-bearing deposits and continued growth in markets business. ⁴
• At the same time, management expected deposit cost to “move up a little bit” in the second half of the year, consistent with interest-bearing deposit mix growth. ²
• They framed interest rates as not a significant factor in or out of the year, and described rate cuts (relative timing vs the original outlook) as only a modest impact on full-year NII expectations. ¹

So, deposit growth served two roles simultaneously:

1. Volume support to NII via higher interest-bearing balances. ¹²
2. Offsetting NIM pressure via deposit cost/increased funding rates—hence the expected Q3 compression. ⁴²

This combination is consistent with management’s explanation that NII can be maintained even when NIM compresses, by relying on balance-sheet growth while the cost/price dynamics play out. ²⁴

4) Markets financing: higher volumes in lower-spread activities supported NII even as NIM compresses

Wells Fargo was clear that parts of markets financing are lower spread but high profitability/returns, and that this activity can still support NII and overall earnings power.

• Management stated that while financing activity impacts net interest margin because it is lower spread, it has “good returns and profitability” and positions Wells Fargo to attract more flow business. ⁵
• They also described ongoing markets-related NII support through financing and related trading activities:
  • They expected market NII to be approximately $2 billion in 2026. ¹
  • They described markets financing/trading growth as meaningful: financing revenue up roughly “pretty close” to double year over year, and trading-related revenue up “roughly a 20 plus percent” year over year. ⁶
  • They cited evidence of markets momentum: total revenue in the markets business grew 24% from a year ago, and returns were starting to increase along with market share. ⁴

This matters for the question because the company expected NIM compression in Q3 while maintaining full-year NII guidance—so markets financing was likely the volume/earning contribution counterweight that can keep NII from falling even when the margin temporarily softens. ²⁵⁶

5) Putting the pieces together: why Q3 compression doesn’t break the $50B NII target

Management’s own “mechanics” for the trajectory were:

• They expected modest NIM compression in Q3 broadly in line with Q2’s decline from Q1, followed by stabilization in Q4. ²
• They attributed near-term NIM softness primarily to deposit growth (interest-bearing deposits) and continued markets business growth, both of which are consistent with the idea of more volume at a mix that temporarily pressures margin. ⁴
• At the same time, they maintained confidence in reaching $50B +/- full-year NII by pointing to balance-sheet growth and repricing across the earning asset base, plus the expected second-half earning asset and activity step-up. ²⁷
• They also noted that the company’s outlook includes a $48B full-year NII excluding markets, alongside the expectation that market NII is about $2B—together supporting the ~$50B framework. ³¹

Conceptual answer to your question:

• Loan balances grew strongly and were expected to continue with upside in the back half. ³
• Interest-bearing deposits grew quickly, supporting earning asset funding balances but also driving deposit-cost pressure, which explains the expected Q3 NIM compression. ⁴²
• Markets financing was expected to continue contributing to markets NII (about $2B in 2026) and rising trading-related revenue, helping protect total NII even when reported NIM compresses in Q3. ¹⁶

Together, these drivers provide a coherent rationale for staying near full-year NII guidance ($50B +/-) while accepting temporary Q3 margin compression and aiming for stabilization in Q4 once the mix/cost dynamics and earning-asset repricing flow through. ²¹
