The US banking sector is entering a more investable phase, but not a simpler one. The easy bear case of 2023 was that deposit flight and unrealized securities losses would compress earnings across the industry. That proved directionally right for many regional banks, yet the sector did not break: capital ratios held, insured deposits stabilized, and the largest lenders continued to produce double-digit returns on tangible common equity. The harder question for bank equity investors now is whether net interest margins are nearing a trough before credit costs absorb the benefit of lower funding pressure.
My base case is that industry NIM bottoms over the next two to three quarters, but the recovery will be uneven and capped by three forces: deposit betas that remain structurally higher than the last cycle, slower loan growth, and a credit mix that is shifting from benign normalization to selective stress in commercial real estate and unsecured consumer lending. That favors banks with low-cost primary deposits, diversified fee revenue, and excess capital over lenders dependent on brokered deposits, wholesale funding, or concentrated office exposure.
Net Interest Margins: The Trough Is Close, Not Yet a Tailwind
The FDIC reported that the US banking industry net interest margin was 3.17% in the first quarter of 2024, down 10 basis points sequentially and below the 2023 peak as funding costs caught up with asset yields. The absolute level is not alarming by historical standards; it is close to the pre-pandemic range. The problem is the direction and the composition. Banks are earning more on loans and securities, but the marginal dollar of deposits is no longer free or sticky.
In the zero-rate era, noninterest-bearing deposits became an underappreciated earnings asset. That subsidy is fading. Corporate treasurers, affluent households, and small businesses have discovered Treasury bills, money market funds, and sweep products. With fed funds at 5.25% to 5.50%, customers have been rationally repricing cash. Industrywide noninterest-bearing deposits have fallen materially from their 2021 highs, and interest-bearing deposit costs have continued to rise even after the Fed paused. This lag is why NIM pressure persisted after the rate cycle stopped moving higher.
The large banks are better positioned because they own transaction relationships, not just balances. JPMorgan Chase still benefits from a massive retail and corporate operating-deposit base, while Bank of America, Wells Fargo, and Citigroup have scale advantages in liquidity management and payments. Even so, management teams have been guiding investors to lower net interest income versus 2023 peaks. JPMorgan’s 2024 net interest income guide around the low-$90 billion area remains extraordinary, but the debate is about sustainability, not peak power. Wells Fargo has been more exposed to NII decline because its franchise is heavily spread-driven and still operating under an asset cap.
For regional banks, the margin outlook depends less on the Fed’s first rate cut than on deposit mix. A 50 basis point decline in short rates does not automatically expand NIM. Many loans, securities, and cash balances reprice down quickly, while deposit costs often fall only after customers stop demanding competitive yields. Banks with high cumulative deposit betas may enjoy relief, but those that retained deposits by paying up will not see an immediate reset. The sequencing matters: early cuts can be NIM-neutral or even negative; a steeper yield curve is the more powerful earnings catalyst.
Loan Growth Is the Missing Multiplier
Even if margins stabilize, revenue growth needs balance sheet growth, and loan demand is subdued. Senior Loan Officer Opinion Survey data through 2024 showed banks continuing to tighten standards across commercial and industrial loans, commercial real estate, and portions of consumer credit. Borrowers are also less eager to add leverage when working-capital loans cost 7% to 9% and property refinancing economics are impaired.
Commercial and industrial lending has been soft because corporate clients built liquidity during 2020-2021 and have since favored bond issuance when markets are open. Investment-grade borrowers can bypass banks, while middle-market borrowers are facing tighter covenants and higher spreads. This leaves banks competing for fewer high-quality loans and protecting capital against criticized assets. A low-growth balance sheet makes cost discipline and fee income more important to earnings per share.
Consumer lending is mixed. Prime credit card and auto borrowers are still employed, but excess savings have normalized and delinquency rates have moved above the unusually low pandemic levels. Mortgage banking remains depressed by affordability: a 7% mortgage rate and home prices near record highs reduce refinancing volumes and limit purchase activity. Banks with wealth management, card interchange, investment banking, and treasury services can offset spread pressure; monoline lenders cannot.
The margin story is not simply about when the Fed cuts. It is about whether banks can replace expensive deposits with stable operating balances while adding assets at attractive risk-adjusted spreads.
Credit Quality: Normalization Has Already Happened, Selective Stress Is Next
Credit is not deteriorating in a 2008-style way, but the direction is unmistakably worse. The FDIC’s industry net charge-off rate was roughly back near long-run norms by early 2024 after the artificially low loss environment of 2021 and 2022. That matters for valuations because bank earnings power during the last two years was flattered by reserve releases and unusually benign consumer credit. Going forward, provision expense is more likely to be a recurring cost than a source of upside.
Commercial real estate remains the key tail risk, especially office. Moody’s Analytics estimated US office vacancy near 20% in 2024, the highest in the modern series, as hybrid work reduced space demand and higher cap rates pressured valuations. Office buildings financed at 3.5% coupons and 60% loan-to-value ratios can become problem assets when refinancing rates double and appraisals fall 25% to 40%. This is a valuation problem before it is a payment problem, which means losses may emerge slowly through modifications, extensions, and selective foreclosures.
Regional and community banks carry the larger CRE concentration. Smaller banks account for a disproportionate share of US commercial real estate lending because they historically competed on local underwriting knowledge and relationship pricing. That model works when collateral is liquid and rent rolls are stable. It is less forgiving when office tenants downsize, multifamily supply rises in Sun Belt markets, and cap rates reset higher. Investors should watch CRE loans as a percentage of risk-based capital, criticized loan migration, and reserve coverage by property type rather than relying on headline delinquency ratios.
Consumer credit is a second watch item. Credit card charge-offs at major issuers such as Capital One, Discover, JPMorgan, and Synchrony have moved materially higher from pandemic lows, with subprime and lower-prime cohorts weakening first. This is not surprising: wage growth has cooled, stimulus cash is gone, and revolving balances are expensive. The offset is that household debt service as a share of income remains far below pre-2008 extremes, and unemployment has not broken higher. The base case is a normal credit cycle, not a household balance-sheet crisis.
Capital, AOCI, and Regulation Still Shape Equity Value
Bank valuation cannot be separated from capital rules. Unrealized losses on securities were still a major constraint in 2024, with the FDIC reporting more than $500 billion of unrealized losses across available-for-sale and held-to-maturity portfolios after rates rose. These marks do not automatically hit regulatory capital for many banks, but they reduce flexibility. A bank with large accumulated other comprehensive income pressure is less able to sell securities, reposition duration, repurchase stock, or pursue acquisitions.
The market is also pricing uncertainty around the Basel III Endgame proposal and potential revisions. Higher capital requirements would lower return on equity unless banks reprice loans, reduce risk-weighted assets, or shift activity outside the regulated balance sheet. The largest banks have already been managing toward higher common equity Tier 1 buffers. JPMorgan, Bank of America, Citigroup, Morgan Stanley, and Goldman Sachs have more levers, including fee businesses and capital markets activity. Regional banks with spread-heavy models have fewer offsets if capital requirements rise.
This is where valuation discipline matters. A simple bank equity framework is price-to-tangible book equals sustainable return on tangible common equity minus growth, divided by cost of equity minus growth. If a bank can earn a 13% ROTCE with 3% long-term growth and a 10% cost of equity, a 1.4x to 1.5x tangible book multiple is defensible. If credit costs push ROTCE to 8% and the cost of equity rises to 12%, fair value falls toward 0.6x to 0.8x tangible book. The gap between winners and losers is not cosmetic; it is the entire investment case.
Equity Market Implications: Own Quality, Avoid False Cheapness
The sector is no longer a blanket short, but it is also not a blanket value trade. Money-center banks deserve premium multiples because they combine deposit scale, payment rails, credit card data, trading, wealth management, and investment banking optionality. JPMorgan’s premium to tangible book is not merely a Jamie Dimon halo; it reflects through-cycle returns, fortress liquidity, and the ability to gain share when weaker competitors retrench. Bank of America offers more rate sensitivity through its securities book and deposit base, while Wells Fargo has self-help upside if regulatory constraints ease.
Super-regionals require more selectivity. PNC, U.S. Bancorp, Truist, Fifth Third, and Regions all have credible franchises, but the market is correctly differentiating based on deposit costs, CRE exposure, fee mix, and capital build. The best opportunities will be banks that show sequential NIM stabilization, stable noninterest-bearing deposits, and no acceleration in criticized loans. A low price-to-tangible book multiple is not enough if tangible book is vulnerable to credit marks or if the earnings base is structurally lower.
The weakest risk-reward sits in banks with concentrated CRE books, above-peer wholesale funding, thin reserve coverage, and limited fee income. These stocks can rally sharply on rate-cut expectations, but rallies are often duration trades rather than fundamental upgrades. If the Fed cuts because inflation is controlled and growth remains positive, banks can work. If the Fed cuts because unemployment is rising and credit costs accelerate, lower rates will not rescue earnings estimates.
What to Watch Over the Next Two Quarters
Investors should focus on four indicators. First, deposit cost stabilization: if interest-bearing deposit costs stop rising before asset yields roll over, NIM troughs become visible. Second, loan beta on the way down: floating-rate assets will reprice quickly, so banks need deposit relief to keep spreads intact. Third, criticized and nonperforming CRE migration: charge-offs are lagging indicators, while internal risk-rating changes show where losses are forming. Fourth, reserve builds: a bank adding reserves ahead of peers may be conservative, but a bank with rising delinquencies and flat reserves is taking earnings risk.
My sector stance is constructive but barbelled. I would own high-quality large-cap banks and select super-regionals with clean deposit franchises, while avoiding lenders where cheap valuation is a function of unresolved CRE and funding risk. NIM pressure is closer to the end than the beginning, but credit quality is moving in the opposite direction. In bank stocks, that combination argues for selectivity, not beta. The next re-rating will accrue to institutions that prove they can defend margins without under-reserving for the cycle that is now arriving.
