Strait of Hormuz Disruptions Spark Commodity Price Surge
The a16z newsletter analyzes recent disruptions in the Strait of Hormuz that briefly halted ship traffic beginning around March 1 and triggered sharp commodity-price moves and market volatility. Large shares of global seaborne commodities (including roughly one-third of world oil) transit the Strait, and fears of prolonged closure drove oil and other commodity prices higher; oil rose about 45% from March 6 to a March 9 peak before retreating. The US Oil Fund (USO) saw historic trading volume (~$16B) on March 9. The piece also discusses a broader market rotation: heavy AI infrastructure capital expenditure is shifting investor preference toward capital‑intensive, asset-heavy companies after a long run for asset-light software. Finally, the newsletter notes labor and platform dynamics in ridesharing—average gross driver pay near $23/hr, platform fees rising faster than driver pay, and ridesharing NPS around 18.
The story documents a major global trade chokepoint disruption that produced extreme commodity-price moves and trading volume, plus a market rotation driven by AI capex—relevant macro developments for investors and infrastructure sectors, but not an immediate industry‑shifting policy or platform change for AdTech/MarTech.
