Not Just Banks: 3 Trading Stocks to Watch After the Fed Rate Hike

The Federal Reserve raised its benchmark overnight rate by 25bps on Sept. 16, its first increase in three years, as energy-driven inflation intensified after Iran war-related disruption pushed WTI crude from below $60 per barrel in January to more than $105 in September. Higher short-term rates favor brokers and exchanges through faster repricing of client cash and margin balances: Interactive Brokers estimates each 25bps hike adds $81M of annual net interest income, while CME could benefit from greater demand for SOFR, Fed funds and Treasury hedging products. Robinhood also gains interest revenue exposure, but slower speculative activity could offset those benefits, leaving its outlook more mixed.

Analysis

The clean expression is not simply higher policy rates, but a wider and more persistent distribution of terminal-rate outcomes. CME monetizes that distribution through hedging turnover with limited balance-sheet duration risk; ICE and CBOE are secondary beneficiaries, but CME’s short-rate complex should capture the highest incremental activity. The near-term upside is volume-led rather than rate-level-led, making CME relatively insulated if policy uncertainty rises even as broad equity risk appetite weakens.

IBKR has the strongest operating leverage to additional short-end repricing, but that benefit is vulnerable to a valuation de-rating if higher energy costs reduce client asset values, margin borrowing, or account growth. HOOD is more exposed to this adverse feedback loop: its interest-income tailwind can be outweighed by lower retail options/crypto activity and a decline in higher-beta assets. Thus, the relevant trade is quality of revenue: institutional hedging flow at CME versus retail risk-taking flow at HOOD, not a blanket long-financials position.

Over the next 1-3 months, the October earnings prints should separate sustainable customer-cash economics from temporary event-driven trading. The thesis is falsified if implied Fed-path volatility normalizes materially, CME’s rate-product volumes decelerate to low single digits, or a credible geopolitical de-escalation drives energy lower and restores a predictable disinflation path. Over 6-18 months, prolonged elevated rates favor platforms with scalable clearing and collateral economics, while lenders face deposit-cost and credit-loss pressure that brokers largely avoid.

Key Decisions for Investors

• Initiate a 1-3 month long CME / short HOOD pair, sized beta-neutral. Target 10-15% relative upside if policy-path volatility remains elevated; exit if CME’s October volume commentary weakens materially or HOOD retail engagement accelerates despite tighter financial conditions.
• Maintain IBKR as a watch-list long rather than chase immediately. Enter only after Q3 confirms continued client-cash and margin-balance growth without a material slowdown in commissions; upside requires another policy repricing, while downside is a multiple reset if client assets contract.
• Add ICE to the derivatives-volatility basket on relative weakness versus CME rather than buying regional banks. ICE provides a diversified hedge against a broader rise in rates/volatility, though it has less direct sensitivity to US short-rate hedging than CME.
• Use long CME December calls or call spreads only if implied volatility remains below the expected post-earnings move; avoid naked HOOD downside options after sharp retail-driven rallies because realized volatility can remain structurally elevated.
