The KBW Nasdaq Bank Index—better known by its ticker BKX—tracks 24 of the largest, most liquid U.S. money‑center, regional‑bank and thrift stocks. Consequently, it serves as Wall Street’s real‑time pulse of the domestic banking sector. Nasdaq Global Index Watch
1. Why It Matters
Because banks sit at the heart of credit creation, their share‑price trends often foreshadow broader economic turns. Moreover, the index underlies heavily traded futures, options and a suite of bank ETFs, giving investors efficient ways to hedge or express views on rates, loan growth and regulation.
2. How the Index Is Built
| Step | Rule |
|---|---|
| Eligibility | U.S.‑listed common stocks “primarily engaged in banking” with ≥ 20 % free float and 3‑month avg. price ≥ $2.00. Nasdaq |
| Selection | 24 leaders chosen for market cap and trading liquidity. Nasdaq Global Index Watch |
| Weighting Method | Modified market‑cap: the largest names are trimmed so no stock grows overly dominant. Nasdaq |
| Rebalance Schedule | Quarterly (March, June, Sep, Dec); an annual evaluation each December can refresh the roster. Morningstar |
Therefore, BKX captures national money‑center giants (e.g., JPMorgan Chase, Bank of America) and high‑growth regionals like First Citizens in one basket.
3. Snapshot (May 5 2025)
| Metric | Value |
|---|---|
| Index Level | ≈ 121.8 Nasdaq |
| Base Year / Base Value | 1991 / 250 |
| Dividend Yield | ~3 % (price index) |
| Top Five Weights | JPM, BAC, WFC, USB, PNC (together ~38 %) |
Because BKX is price‑return only, total‑return versions (BKXTR) reinvest dividends.
4. Recent Performance (Price Return, USD)
| Year | % Return | Main Driver |
|---|---|---|
| 2022 | –21 % | Inverted curve, credit fears |
| 2023 | –1 % | Deposit outflows after small‑bank failures |
| 2024 | +31 % | Fed rate cuts steepen curve, NIM recovery |
| YTD 2025 | +8 % | Loan growth rebounds, capital rules clarified |
Volatility (~26 %) runs well above the S&P 500 because earnings swing with rates and credit costs.
5. How Traders & Investors Use BKX
- Macro Gauge: Rising BKX often signals steeper yield curves and looser credit.
- Hedging Tool: CME and Cboe futures/options on BKX let portfolio managers offset regional‑bank risk without shorting single names.
- ETF Underpinning: Funds like KBWB replicate the index almost tick‑for‑tick, offering liquid, diversified bank exposure. Yahoo Finance
- Relative‑Value Pairing: Some desks trade BKX vs. broader S&P Financials to isolate “pure banking” beta.
6. Strengths & Caveats
| Strengths | Caveats |
|---|---|
| Pure U.S. banking focus—no insurers or brokers | 24 stocks mean idiosyncratic moves hit returns |
| Modified cap weighting limits mega‑bank dominance | Still leans heavily on JPM & BAC earnings |
| Decades‑long history aids cycle analysis | Excludes foreign‑listed ADRs like HSBC, BMO |
7. Themes to Watch
- Net‑Interest‑Margin Path: Two expected Fed cuts in H2 2025 could nudge margins slightly lower, yet loan growth may offset.
- Capital‐Rule Finalization: Basel III Endgame clarity is likely to free buyback capacity for money‑centers.
- Digital‑Bank Competition: Regional lenders investing in fintech partnerships may gain share and enter BKX at the next evaluation.
- Credit Cycle: CRE office exposure remains the wildcard—watch charge‑offs in Q3 results.
