The Strait of Hormuz closure is triggering cascading effects across global supply chains, from coal-burning in India to helium shortages for MRI machines, while housing policy battles and semiconductor manufacturing reshuffle the economic landscape.
The closure of the Strait of Hormuz has triggered a cascade of economic disruptions that extend far beyond oil markets, revealing the intricate interdependencies of modern supply chains. As countries scramble to secure energy supplies, the war's impact is manifesting in unexpected ways—from plastic price spikes to helium shortages for medical equipment.
Energy Markets and Industrial Disruption
The immediate response to disrupted oil supplies has been a global pivot back to coal. India is burning more coal to meet higher summer demand, while South Korea has lifted caps on electricity from coal. Indonesia is prioritizing its domestic coal supply, and countries like Thailand, the Philippines, and Vietnam are boosting coal-fired power generation. This regression to dirtier energy sources highlights the fragility of energy transition efforts when confronted with supply shocks.
But petroleum's role extends far beyond fuel. The same Strait of Hormuz closure driving up oil prices is also causing plastic prices to surge. Dow Chemical plans a 30-cent per pound increase in April, following a 10-cent increase in March. Since February, plastic prices have jumped nearly 40%. This affects everything from packaging to construction materials, creating inflationary pressures throughout manufacturing sectors.
Perhaps most concerning is the impact on pharmaceuticals. Petroleum is used in the manufacture of many generic medications, suggesting potential drug shortages could emerge alongside energy and material scarcities. The disruption extends to helium production as well—helium is extracted during natural gas drilling, and its shortage affects more than just party balloons. Liquified helium serves as a coolant for MRI machines, potentially impacting medical diagnostics.
Technology Infrastructure Under Attack
Another AWS data center in the Middle East has reportedly been damaged by an Iranian drone attack, highlighting how critical infrastructure has become a military target. This raises questions about the resilience of cloud computing infrastructure and the potential for cascading failures if key data centers are compromised.
In response to rising gas prices, the EPA is temporarily waiving regulations on ethanol-blended gasoline sales. These restrictions, typically in place to reduce air pollution in certain locations during specific times of year, are being lifted to increase fuel supply—a trade-off between energy security and environmental protection.
Economic Winners and Losers
Iran has established a "safe shipping corridor" through the strait, allowing ships to pass for a $2 million fee. This creates a perverse incentive structure where the country benefits financially from the very disruption it's causing.
Interestingly, Chinese battery manufacturers are experiencing a boom. Since the start of the war, their stocks have spiked significantly: CATL's shares are up 19%, Sungrow is up 19.4%, and BYD has gained 21.9% since the US-Israeli strikes began at the end of February. This suggests that the energy transition may be accelerating in some regions, even as others revert to coal.
Housing Policy Battles
The proposed ROAD to Housing Act has become a flashpoint in American housing policy. The bill includes a provision preventing the construction of build-to-rent single-family homes, which critics argue would make it harder, not easier, to build homes when the country desperately needs them. Senator Elizabeth Warren is reportedly unhappy about resistance to these provisions and is sending vaguely threatening letters to investors in multifamily apartments and manufactured homes.
Meanwhile, Fannie Mae's decision to allow mortgages backed with cryptocurrency represents another frontier in housing finance. The partnership between Better Home & Finance and Coinbase Global allows homebuyers to pledge their crypto holdings when getting a Fannie-backed mortgage, instead of selling crypto to make a cash down payment. This innovation raises questions about risk assessment and the potential for market volatility to affect housing stability.
Manufacturing Reshuffles
Elon Musk's announcement of "Terafab," a semiconductor fab to make chips for Tesla cars, Optimus robots, and space-based data centers, underscores the strategic importance of semiconductor independence. "We either build the Terafab or we don't have the chips," Musk said at an Austin event. "We need the chips, so we're going to build the Terafab."
This move reflects a broader trend of companies bringing critical manufacturing capabilities in-house to reduce supply chain vulnerabilities. As geopolitical tensions and trade disruptions continue, we can expect more companies to follow Tesla's lead in vertical integration.
The Luxury Mall Paradox
In an unexpected twist, some US malls are thriving, but only the high-end ones. The top 100 malls account for 50% of the entire sector's value, while the bottom 350 make up just 10%. Revenue at Class A malls is growing by 5% annually, and financing is readily available. This bifurcation suggests that experiential retail and luxury goods may be more resilient to e-commerce disruption than previously thought.
These developments paint a picture of an economy in flux, where traditional supply chains are being tested, new technologies are creating both opportunities and risks, and the winners and losers of global disruptions are not always predictable. As the war in Iran continues to reshape energy markets and supply chains, the full extent of these second and third-order effects may take months or years to fully manifest.
