For several decades, the “Lean” supply chain model, exemplified by Just-in-Time (JIT) delivery, has been regarded as the paragon of efficiency, significantly reducing costs and facilitating global trade. Its fundamental premise is straightforward: seamless operations, minimal waste, and timely arrival of products. Companies achieved substantial savings by rigorously eliminating inefficiencies, such as surplus inventory, and depending on single optimised suppliers. Prior to the COVID-19 pandemic, global manufacturing inventory buffers were at historically low levels, leaving virtually no margin for any disruption. A stark illustration of lean ‘s vulnerability is the semiconductor shortage that severely impacted the automotive industry, leading to the idling of plants worldwide and resulting in an estimated $210 billion in lost revenue in 2021 alone. However, the once-unassailable foundation of this model is now evidently compromised, as geopolitical tensions and tariffs have disrupted business.
Lean: Once-Perfect System
The fundamental advantage of the lean methodology—its focus on waste elimination and reliance on singular, optimised suppliers—has emerged as a critical vulnerability in a global context where disruptions arise not only from operational or logistical challenges but also from geopolitical dynamics. This system, originally designed for stability and predictability, is increasingly unable to withstand the pressures of ongoing policy-induced volatilities. We are witnessing a shift from isolated disruptions to periods characterised by the strategic use of trade as a geopolitical tool. Currently, the United States is targeting manufacturing centres, including China, India, Brazil, Mexico, and Canada, with a proliferation of tariffs and trade barriers. For example, the United States has implemented import duties of up to 50% on goods from these global manufacturing hubs.
Tariffs: A Systemic Shock, Not Just a Tax
While tariffs are frequently perceived in a simplistic manner as a form of taxation, their true impact is manifested through the pervasive ripple effects they induce across global supply chains. According to the International Monetary Fund (IMF), global trade costs have escalated by approximately 8.5% since 2018, a trend driven significantly by the increase in tariffs. These rising costs compress profit margins and contribute to consumer-level inflation. For example, the National Retail Federation in the US estimates that a 10% tariff on imported apparel can lead to a 3% to 5% increase in retail prices. The impact of this extends far beyond direct costs.
- Tariffs have instigated significant shifts in global supply chain strategies, including “friendshoring”, “nearshoring”, and reshoring. Companies relocating from China frequently encounter new vulnerabilities in their supply chains. A 2024 survey conducted by the Boston Consulting Group (BCG) revealed that 72% of multinational corporations actively diversifying their sourcing due to tariffs reported substantial operational challenges and cost overruns. This ongoing turbulence starkly contrasts with the principles of Lean stability.
- Engaging with intricate rules of origin, tariff classifications, and customs procedures has increasingly become a significant financial burden, such as the rise in trade compliance costs. A 2025 report by PwC indicated that 25% of global companies incurred tariff-related fines in 2024 due to insufficient customs processes.
- Uncertainty poses a significant challenge to capital expenditure. Investments in new production lines or technology are often postponed or cancelled because of concerns regarding future tariffs and the instability of trade policies. If these systems do not align with overall growth, the necessity for continuous optimisation inherent in lean practices will not be realised effectively.
- Tariffs are increasingly utilised not only to address trade imbalances but also as instruments for exerting pressure on nations, addressing national security concerns, and demonstrating geopolitical influence. This multifaceted application introduces an unpredictable element of political risk into every sourcing decision in supply chains.
Tariffs induce a ripple effect that extends significantly beyond mere trade balances, influencing supplier selection, production expenses, and delivery schedules. Each disruption exacerbates the vulnerabilities within streamlined systems. To enhance supply chain resilience, it is essential to adopt diversified sourcing, flexible logistics, and strategic buffers, thereby mitigating policy-induced disruptions without impairing operations or customer service. Numerous industries are experiencing substantial pressure from tariffs, necessitating significant alterations to their supply chains and operational strategies for survival. In the electronics sector, Apple, which is heavily dependent on Chinese manufacturing, is diversifying its supply chain with the objective of relocating 15–20% of its production to India and Vietnam by 2026. This strategic initiative is financially demanding and involves significant investment. In the retail sector, Walmart reduced its Chinese imports by 10% in 2024, opting to source from Vietnam and Thailand, which resulted in a 5% increase in logistics costs due to extended shipping routes. Other retailers, such as Target, have implemented selective price increases, particularly on non-essential goods. Numerous examples exist across industries.
Need of Hour: Robustness and Resilience in Supply Chains
The lesson is clear: efficiency is no longer king; survival demands robustness (the ability to absorb shocks) and resilience (the capacity to recover and adapt). These concepts clash directly with lean orthodoxy. Robustness requires strategic buffers – inventory for critical components and spare capacity – that Lean labels as “waste”. Resilience demands supplier and geographic redundancy, dual-sourcing, and flexible manufacturing – the opposite of lean ‘s single-source, hyper-synchronised ideal. The departure is inevitable. A 2023 Gartner survey of over 1,300 supply chain leaders globally found that 89% now prioritises resilience above cost efficiency. Supply chain leaders are now actively exploring and investing in nearshoring to increase supply resilience.
The changing dimension of “China Plus One”
Numerous companies have been relocating production from China to countries such as Vietnam, Mexico, or India, a strategy commonly referred to as “China Plus One.” However, this approach, although straightforward, is insufficient and potentially fraught with risk. Relocating to Vietnam does not eliminate the risk; rather, it merely redistributes it. Since 2020, Vietnam’s manufacturing costs have increased by 20% due to heightened demand, rising wages, and anticipated tariffs. The optimal solution involves diversifying sources and locations for production, thereby distributing the risk across various regions and suppliers. According to a study by Deloitte, 40% of U.S. companies intend to relocate segments of their supply chains to North America by 2026, with investments also being made in the domestic production of critical items. Additionally, companies are maintaining surplus inventories of essential items to mitigate disruptions, marking a shift from lean inventory practices to more conservative approaches. Toyota, for instance, adopted this strategy following the 2011 earthquake and now maintains additional inventory at strategic locations to enhance supply chain resilience. It is conceivable that future supply chain management will incorporate tariff-linked inventory policies to navigate dynamic conditions and counteract uncertainty.
Conclusion
Enhancing robustness and resilience necessitates financial investment, which exceeds the costs associated with an ultra-lean model. Strategic buffers require capital allocation, and engaging multiple suppliers often incurs higher unit costs than a single, optimised source. Nevertheless, the consequences of failing to adapt are significantly more severe, including lost sales, declining market share, reputational damage, and potential bankruptcy. Geopolitical tensions and climate change contribute to persistent volatility. Tariffs are increasingly used as strategic tools. Businesses that rely solely on lean principles are building precarious foundations. Successful entities will excel in a dual mandate: relentlessly pursuing efficiency where feasible and intentionally investing in robustness and resilience when necessary. As Karen Lamb, Chief Supply Chain Officer at Honeywell, once starkly put it, “Lean taught us to cut the fat. Now, we must build the muscle. Muscle to take the punches of this volatile world and come back swinging. Efficiency keeps the lights on; resilience keeps you in the game.”
The period characterised by brittle, hyper-efficient, and optimised supply chains has concluded, giving way to an era marked by resilience and adaptability in the face of challenges. Regional supply chains, which enhance resilience and counter ripple effects, are poised to dominate global markets in the foreseeable future.
