War rewrites the rules of interest rates, and swap rates reveal the rhythm of war.

Five-year swap rates repriced sharply after the Middle East war: USD SOFR +20 bps, euro swaps +30 bps and GBP SONIA nearly +45 bps between Feb 27 and Mar 6, reversing expectations for 2026 rate cuts. Oil-driven supply shocks lifted inflation expectations, tightened central bank policy space, triggered a trade-weighted USD safe-haven rally and pressured tech valuations via higher discount rates.

Analysis

The dominant marginal driver right now is a term‑premium repricing anchored in commodity‑supply risk, which transmits nonlinearly into nominal curves and cross‑currency basis. For a typical long‑duration growth equity (duration ~8–12 years), a 25–50bp upward shift concentrated in the 3–7y segment implies an immediate mark‑to‑market decline on the order of 2–5% and a disproportionate hit to leveraged strategies; this is distinct from a pure policy‑rate shock because it carries a persistent risk premium component.

Second‑order plumbing effects matter: banks and non‑bank dealers will widen lending spreads and demand larger term premia for warehousing FX and commodity inventories, effectively raising corporate funding costs — a 50bp swap repricing adds roughly $5m of annual interest expense for every $1bn of floating debt. This also creates asymmetric hedging flows (sell OIS, buy raw commodity hedges) that amplify volatility in the 1–12 month horizon and can overwhelm classical duration‑based hedges.

Catalysts that can reverse the move are event‑driven and fast (diplomatic de‑escalation, coordinated SPR releases, visible unblocked shipping lanes) versus structural and slow (real sustained shift to higher energy risk premia, fractured market liquidity). Tail risks to the upside include prolonged supply chokepoints or widening cross‑currency funding stress; tail to the downside is a rapid policy/coordinated market response that compresses risk premia and re‑steepens the curve in favor of risk assets within 30–90 days.

Key Decisions for Investors

• Trade 1 — USD hedge / tactical long: Buy UUP (USD ETF) size = 3–5% NAV, horizon 1–3 months. Entry on up‑leg or DXY pullback of ~1–2%; stop‑loss 3% from entry, profit target 6–9%. Rationale: asymmetric hedge vs headline de‑escalation; expected reward ~2:1 vs stop.
• Trade 2 — Energy directional with defined risk: Buy a 3‑month WTI call spread (e.g., buy $70 / sell $100 via CL futures or USO options), not naked calls. Max loss = premium paid (small); breakeven ~$70–80 depending on premium; target 2–4x premium if spot remains elevated. Timeframe 1–3 months; hedge against sustained supply premium with capped cost.
• Trade 3 — Curve steepener (relative value): Short 5y Treasury futures (FV) and long 2y futures (TU) — net notional sized to target a 10–15bp move in the 5y‑2y spread, horizon 1–3 months. Risk: central bank action that pushes short rates materially higher; use a 12–15bp stop on the spread. Reward: benefits if middle‑tenor term premium rises more than front end.
• Trade 4 — Growth downside protection: Buy QQQ 3‑month put spread (e.g., long 1 put / short lower strike put) sized to cover 30–50% of equity exposure. Cost‑capped insurance with payout kicking in on a 6–12% equity drawdown; target 3–4x payoff vs premium if volatility persists. Serves as cheap tail hedging against a continued risk‑off repricing of long duration assets.
