Since the introduction of the Ford Model T in 1916 and the recognition of the importance of good roads through legislation like the Federal Aid Road Act of 1916 and the Federal-Aid Highway Act of 1956, the United States has seen significant changes in its supply chains.
The creation of the Interstate Highway System revolutionized freight transportation, making it faster and more cost-effective.
However, in recent decades, a focus on efficiency and globalization has led to heavy reliance on imports, especially from countries like China. While this approach initially brought benefits, recent disruptions have shown vulnerabilities. Events like the COVID-19 pandemic, geopolitical tensions, and natural disasters have exposed the fragility of stretched supply chains.
Moving forward, there's a need to shift towards building resilient supply chains, focusing on diversification, domestic manufacturing, nearshoring, strengthening partnerships, and investing in technology. If the United States wants to mitigate disruptions, enhance national security, and ensure sustained economic growth, they need to embrace resilience.
In this article, we’ll journey through the complexities of modern supply chain management, exploring the challenges and opportunities facing US supply chains. From the global disruptions of the COVID-19 pandemic to the relentless forces of globalization, we'll discuss the intricacies of supply chain resilience and deep dive into strategies for fortifying US supply chains against future disruptions.
In recent decades, our shopping experiences have been shaped by the pursuit of speed and cost savings. Over the past 30 years, countries like China, Canada, and Mexico have become key players in supplying our toys, clothes, and electronics, each specializing in different product categories.
Initially, this globalized approach seemed flawless, but unforeseen events, such as the pandemic and recent geopolitical tensions, disrupted this seamless flow of goods. Suddenly, obtaining essential items became challenging, leaving us feeling disoriented and uncertain — a sensation that has become the "new normal" characterized by complexity and frequent disruptions.
During this period, the United States' supply chain underwent a significant shift, prioritizing efficiency above all else. Globalization pushed manufacturers to seek out the cheapest production hubs, aiming to minimize costs and maximize delivery speed.
While this strategy brought undeniable benefits, it also created a heavy dependence on imports, particularly from China. Consider the data: China dominates a plethora of import categories for the USA, including:
While economies of scale initially promised cost and speed advantages, recent disruptions have exposed the iceberg of vulnerability of this over-dependence on global supply chains.
The COVID-19 pandemic acted as a stark wake-up call, revealing the weaknesses present in our global supply chains.
Lockdowns in China, a major manufacturing hub, immediately disrupted worldwide supply networks. Shortages of essential goods, from personal protective equipment (PPE) to semiconductors, rippled through industries and frustrated consumers.
Beyond the pandemic's immediate impacts, we face additional threats from geopolitical tensions and natural disasters. These events strain our already overreliant and streamlined system, evident in the Red Sea, where attacks on merchant vessels and fuel tankers disrupt vital trade routes.
If anything, the pandemic highlighted the pressing need for the US to reassess and strengthen its supply chains against unexpected disruptions, whether from pandemics, conflicts, or natural calamities.
The previous emphasis on efficiency often neglected redundancy and buffer stocks. The "just-in-time" (JIT) approach, a cornerstone of efficient supply chains, assumes a relatively stable and predictable environment.
Now, let's examine the Inventory-to-Sales Ratio for manufacturers and retailers in the USA.

Now, let's categorize this into pre and post-pandemic states for better understanding:
One notable trend that emerges is that pre-pandemic:
1. Demand was the leading indicator - changes in the inventory-to-sales ratio at the retailer level were followed by manufacturers. However, this has reversed post-pandemic.
2. Initially, supply became the leading indicator - the retailers' inventory-to-sales ratio started to follow the supply bottleneck with manufacturers' inventory-to-sales ratio, which was constantly disrupted after the COVID-19 pandemic and geopolitical conflicts like:
These events shattered the assumption of efficiency, underscoring the fragility of stretched supply chains built on minimal inventory.
As highlighted by the White House Council of Economic Advisers (CEA) in its "Issue Brief: Supply Chain Resilience," the JIT model was simply not prepared for the level of disruption we have been witnessing in the last few years.
The "Issue Brief" further discusses research showing that recent Inflation has been significantly affected by supply chain bottlenecks (Comin et al., 2023; Giovanni et al., 2022). When factories halt and shipping containers accumulate at ports, the cost of goods for consumers inevitably increases, leading to CPI inflation.
This underscores the strong link between supply chain resilience and broader macroeconomic activity (refer to the graph below, which clearly illustrates the causal relationship between Supply Chain Pressures and the Core CPI movement.)
Moving forward necessitates a strategic shift. We must move beyond a solely cost-driven approach and construct resilient networks capable of confronting future challenges. Here are some essential strategies to consider:
The USA has increased its imports from longer distances.
Organizations must break free from conventional thinking and embrace what I would call a radical + out-of-the-box approach.
The advantages of a more resilient supply chain extend beyond mitigating disruptions and inflation; they also bolster national security. A recent report by the McKinsey Global Institute suggests that disruptions in critical supply chains could incur annual costs of up to $2 trillion for the US economy.
Strengthening domestic production in key sectors like semiconductors and pharmaceuticals reduces reliance on foreign sources and mitigates potential national security threats.
Creating a strong and adaptable supply chain demands a collective endeavor. Businesses, policymakers, and consumers each have a crucial role to play.
The journey towards a more resilient US supply chain won't be simple. It will necessitate investments, adaptations, and a mindset of ‘innovation + change’. Yet, the potential benefits — a more stable economy, reduced inflation, and heightened national security — make this transition worthwhile and necessary.
By prioritizing and embracing resilience, we can mitigate inflation risks and ensure that the US supply chain remains a vital driver of economic growth and global competitiveness.
