Supply Chains and Global Trade

Somewhere in Shanghai in mid-2021, a single container of ammonium phosphate sat buried among tens of thousands of boxes, waiting for a ride to the US Midwest. It had been there since May. Typhoons, COVID outbreaks, and container shortages had turned a journey that normally takes weeks into a half-year ordeal — and counting. The fertilizer was manufactured in Chongqing, 2,400 kilometers from the coast, in February. By August it still hadn't left China.¹

The story is a microcosm of the pandemic's exposure of something economists and supply chain professionals already knew but the public hadn't internalized: modern global trade is a system of breathtaking complexity running on razor-thin margins, and when it breaks, it breaks everywhere at once.

The Cascade

The container's journey illustrates how disruptions compound. The initial delay was a shortage of empty containers — the crucial return of steel boxes from trips to the US and Europe had been disrupted by understaffing and a lack of trucking equipment to move goods out of ports. Chongqing, surrounded by mountains, was especially hard to reach. Once containers were secured, the eight-day barge trip down the Yangtze went smoothly, but freight rates had skyrocketed because shipping lines were pulling smaller coastal vessels off to use on the lucrative Trans-Pacific routes.¹

Then Shanghai. Yantian port in Shenzhen closed due to a COVID outbreak in May, creating congestion across the entire eastern coast. Ningbo, the world's third-busiest container port, redirected shipping after one employee tested positive. Typhoon In-Fa shut Shanghai for four days. Meanwhile, seven other boxes from the same fertilizer order found their way to Chicago — but this one stayed stuck, buried "like the crate in the final scene of Raiders of the Lost Ark."

Even after leaving Shanghai, the risks weren't over. Thirty-five ships were anchored outside the twin ports of Los Angeles and Long Beach, waiting for berth space. Then one to three months more by rail or truck to Chicago. The logistics coordinator, Steve Kranig, was already back ordering eight more containers for the next round. Same delays, repeating.

All Roads Lead to China

"All roads lead back to China," observed Dawn Tiura of the Sourcing Industry Group. "Congestion at one port or factory has far-reaching implications for neighboring facilities, which trickles out across the world." The supply chain crisis revealed that the much-vaunted diversification of global trade was somewhat illusory — most supply chains still passed through Chinese ports, factories, or shipping lanes at some point.

This concentration has deep historical precedent. The East India Company — founded in 1600, dissolved in 1874 — was at its peak the largest corporation in the world, with its own army of 260,000 soldiers (twice the British army's size) and operations that accounted for half of world trade in the mid-1700s. It didn't just trade in the Indian Ocean region; it ruled large parts of the Indian subcontinent, exercised military power, and assumed administrative functions.²

The EIC is worth thinking about because it demonstrates that the blurring of corporate and state power in global trade isn't a modern phenomenon. The company's charter gave it a monopoly on English trade east of the Cape of Good Hope. Traders operating without its license faced forfeiture of ships and cargo, plus imprisonment. Its operations "almost single-handedly reversed the trend of eastward drain of Western bullion, seen since Roman times." The current anxiety about corporate power in supply chains — Amazon controlling logistics infrastructure, shipping lines consolidating into three major alliances — is a recurrence, not an innovation.

Fragility and Efficiency

The supply chain crisis prompted a reconsideration of just-in-time inventory management. The system that Toyota pioneered — minimizing inventory to reduce waste and capital costs — works brilliantly when trade flows smoothly. When it breaks, there's no buffer. A single Suez Canal blockage, a single COVID outbreak at a single port, can ripple across the entire global economy.

The question is what replaces it. Gabriel Rossman's prediction about the post-COVID economy was stark: "I expect to see a trend away from just-in-time inventory and globalization and towards economic autarky and a preference for slack over efficiency." The tradeoff is real — slack costs money in normal times. But as the container of fertilizer demonstrated, the cost of fragility in abnormal times can be enormous, cascading through agriculture, manufacturing, and ultimately onto dinner tables and holiday shopping.

The deeper lesson is about the difference between efficiency and resilience. An efficient system minimizes cost under normal conditions. A resilient system performs adequately under abnormal conditions. These are different engineering objectives, and optimizing for one degrades the other. The pandemic didn't create this tradeoff — it revealed it, at a scale that made it impossible to ignore.
