How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| DUBAI_CRUDE | restricted Gulf export flows and elevated transit risk at Hormuz under US enforcement tighten regional supply and benchmarks linked to Gulf grades | Up1-5d | Coverage ties higher crude prices and supply concerns directly to US insistence it can maintain the naval blockade indefinitely and to shipping slowing to a trickle |
| NMM | tanker and dry bulk owners gain from higher war‑risk premia and rerouting that raise effective freight rates despite stranded vessels | Up1-4w | Shipping data show near‑zero passage through Hormuz and analyses highlight insurance premiums surging many‑fold amid blockade and attacks |
| USD | on one hand, safe‑haven flows support the dollar; on the other, higher oil and inflation fears weigh on risk sentiment and could complicate US policy expectations | Mixedintraday | Global markets reports note rising oil and yields blunting equity gains, while broader commentary links Middle East tensions to cross‑asset volatility |
