Commentary: Prepare for a Brutal Reckoning as the Strait of Hormuz Closes

1. On March 2, Iran retaliated against recent US and Israeli military actions by announcing the closure of the Strait of Hormuz, a critical maritime chokepoint for global energy flows. Approximately 20% of the world’s crude oil and a comparable portion of liquefied natural gas (LNG) transit through the strait, including nearly all LNG exports from Qatar, a top-three global LNG supplier. This closure threatens a substantial disruption to global energy transportation and supply chains. [para. 1]

2. Iran possesses the practical ability to blockade the Strait of Hormuz due to its geography—its narrowest stretch is just 38.9 kilometers wide, well within artillery range. Iran can also employ drones to target passing vessels. The credible threat means insurance companies may withdraw coverage and shipping companies might refuse to transit the strait, essentially halting traffic without direct confrontation. [para. 2]

3. The immediate direct impact of the blockade is a sharp contraction in global oil and gas supply—about 20%—which has already driven Brent crude futures up from around $70 to $108 per barrel in just one week (as of March 9). Beyond higher commodity prices, there have also been surges in freight and insurance costs, amplifying the disruption's economic toll. [para. 3]

4. Iran’s robust retaliation highlights an assertive capability and resolve, with the recent elevation of Ali Khamenei's son as Iran’s supreme leader reinforcing expectations of a continued hardline stance. Oil prices are thus likely to remain elevated above $100 per barrel for the foreseeable future, with potential global economic ramifications. [para. 4]

5. Escalating oil prices feed directly into consumer costs, not only raising gasoline prices but also inflating costs throughout the chemical industry, which relies heavily on crude oil as a raw material. As oil is a globally traded commodity, price shocks are transmitted worldwide, affecting even traditionally energy-sufficient countries like the US. This creates a classic supply-side shock, generating inflation across continents. [para. 5][para. 6]

6. Rapidly accelerating inflation can stall economic growth—a phenomenon known as stagflation, which Western economies endured after previous oil crises in the 1970s and 1980s, with US Consumer Price Index inflation peaking at 12% and 14%. The current situation risks triggering a similar scenario. [para. 7]

7. In the face of inflation, the US Federal Reserve may be forced to abandon any rate-cutting plans, potentially resuming interest rate hikes despite political pressure from President Donald Trump to reduce rates. Even if official rates hold steady, long-term yields will rise as bond investors demand higher returns amidst inflationary risks. [para. 8][para. 9]

8. Higher interest rates would increase federal borrowing costs, compounding existing fiscal pressures. The US ran a $1.8 trillion deficit last year, and the reliance on short-term debt creates financial fragility. If the Fed cuts rates in the face of inflation, it could drive investors away from US Treasurys and jeopardize confidence in the dollar. [para. 10][para. 11][para. 12]

9. The US financial system is already under strain from liquidity shortages, visible in the Treasury’s dependence on short-term debt and emerging problems in the private credit market. Volatility in tech stocks and falling cryptocurrency values further indicate surface-level robustness masking deeper vulnerabilities. A spike in yields toward 8% or more could trigger systemic liquidation, echoing the 1974 crash in which the S&P 500 halved in value. [para. 13][para. 14][para. 15][para. 16]

10. Globally, inflation from higher oil prices will push up interest rates and suppress equity valuations. Stock markets in Japan and South Korea are already reacting negatively due to concerns over the strait’s closure. Rising Japanese rates might also force the unraveling of the yen carry trade, leading to the sale of US assets and destabilizing both economies. Japan may attempt to avert this with quantitative easing, risking sharp yen depreciation and further inflation. [para. 17][para. 18][para. 19]

11. For China, currently battling deflation, the direct inflationary impact will be muted, but a global recession would damage Chinese export demand. However, China still has significant fiscal and monetary flexibility to mitigate these effects. [para. 20][para. 21][para. 22]
