For decades, global supply chains were built on a relatively stable set of assumptions. Companies optimized cost, leaned on predictable trade relationships and focused on efficiency over resilience. That approach delivered measurable gains in a period when geopolitical shocks, regulatory changes and widespread disruptions were comparatively rare.
Those conditions no longer exist. In recent years global volatility has revealed just how quickly long-held assumptions can become liabilities by exposing vulnerabilities that were once hidden deep within global supply chain networks.
The challenge is that many companies are making decisions based on incomplete information. According to Harvard Business review, only 16% of companies have visibility across all tiers of their supply chain, leaving most businesses unable to see where critical materials originate or where hidden dependencies exist. As procurement becomes more strategic, organizations are shifting from supplier-centric decision-making toward a product-centric view. Having a more complete understanding of where the materials and components for their products originate gives businesses significantly more control when navigating uncertainty.
The following 10 assumptions illustrate why traditional supply chain thinking is becoming less reliable in today’s operating environment and how procurement strategies should evolve in response.
1. Why lowest-cost sourcing can increase supply chain risk
Many companies have fallen into the habit of automatically selecting the most affordable suppliers, but this approach doesn’t consider a supplier’s reliability or resilience. A supplier that appears economical on paper may become expensive when production delays or sourcing issues are factored in.
Instead of selecting the cheapest supplier and hoping that disruptions never occur, companies should anticipate and plan for worst-case scenarios. What does the financial health of the supplier look like? What risks might prevent them from fulfilling their obligations, and which are most pertinent to your business? Answering questions like these can help. So can creating a structured procurement framework that incorporates potential risk. The result is more nuanced, successful decision-making.
2. How geopolitical chokepoints disrupt global supply chains
The ongoing conflict in the Strait of Hormuz shows just how profound the impact of international relations can be on global supply chains. Before the start of the 2026 Iran War, approximately 25% of maritime oil depended on the passage. Recent blockages in the strait have caused oil and natural gas prices to skyrocket, leading to downstream effects in transportation and other industries.
As this example shows, assuming that trade ports, canals and hubs will remain accessible can be a costly oversight for businesses. Instead, companies need to account for political uncertainty in their contingency planning. Diversifying suppliers accordingly helps ensure they can continually secure the components and materials their products need.
3. Supply chain compliance vs. transparency: What’s the difference?
While essential to conducting business, meeting regulatory requirements does not equate with full transparency into your supply chain. Suppose, for instance, you have confirmed that your direct suppliers follow appropriate criteria for environmental and labor practices. Without complete transparency, you might not realize that a lower-tier supplier does not satisfy those requirements.
True transparency requires a nuanced understanding of the entire supply chain, including direct and indirect suppliers, to fully understand the origin of all materials and associated risks.
4. Why a “China Plus One” strategy doesn’t eliminate supply chain risk
Many companies follow a “China Plus One” strategy, in which they diversify geographic sourcing to avoid overreliance on China. This strategy can be useful to improve supply chain resilience, but it doesn’t guarantee risk reduction.
Simply shifting final assembly outside of China doesn’t prevent suppliers in these new locations from relying on Chinese materials or labor in their own supply chains. Additionally, these new geographic areas may introduce a new set of risks, like political instability, natural disasters or trade restrictions.
Without a clear understanding of the new risks being introduced, and without insight into lower-tier suppliers, companies may be shifting risk rather than reducing it. Successful diversification requires looking beyond where products are assembled to understand the entire supply network.

5. How trade regulations affect supply chain and sourcing decisions
Governments are using trade policy to advance broader economic, environmental and national security objectives. The resulting regulations directly influence where companies can source materials and which suppliers they can work with.
For this reason, organizations that integrate regulatory intelligence into sourcing and procurement decisions are better equipped to adapt. This holds true as trade rules evolve and new legislation emerges across different regions. Rather than treating compliance as a final checkpoint, leading companies are embedding it into supply chain strategy from the outset.
6. How financial and geopolitical risks affect supply chains
The global exchange of goods requires well-oiled financial systems. When those financial systems are disrupted, supply chains can suffer just as severely as when a factory shuts down or transportation is restricted. For instance, economic sanctions may prevent companies from paying suppliers, while currency fluctuations can dramatically increase sourcing costs.
These financial risks are becoming increasingly intertwined with geopolitical events. As a result, supply chain risk management now depends on evaluating supplier financial health, monitoring geopolitical developments and understanding exposure to sanctions, currency volatility and banking disruptions.
7. The supply chain risks of “just-in-time” inventory
By following the “just-in-time” approach to manufacturing and procurement, companies have historically been able to reduce inventory costs, minimize waste and improve cash flow. While this approach can be effective during periods of global stability, it also comes with limitations.
Most notably, when combined with concentrated supplier networks, the strategy gives a single event the power to halt production and create shortages. Japan’s devastating 2011 earthquake and tsunami was the perfect example of this, leaving companies in the automotive, electronic and semiconductor industries without key components for their products.
Without alternative sourcing options, even a minor delay can have significant operational and financial consequences. Companies must adopt more flexible inventory strategies, such as dual sourcing and using regional suppliers, to balance lean spending with risk mitigation.
8. How strategic inventory builds supply chain resilience
For many years, excess inventory was viewed as an unnecessary cost due to greater storage expenses and unrealized revenue. As a result, many organizations focused on reducing inventory wherever possible.
However, this strategy can leave companies without essential components when disruptions arise. In many cases, the cost of carrying extra inventory is lower than the financial impact of production shutdowns, missed customer commitments or emergency sourcing.
The challenge is finding the right balance. Maintaining surplus for high-risk or business-critical items can help. Risk analytics and supply chain visibility allow companies to determine where extra inventory can add the most value, allowing them to optimize for cost, continuity and resilience.
9. Why multi-tier supply chain visibility is essential
Many organizations have clear visibility into their direct suppliers but remain largely unaware of upstream risks. This is potentially destructive because a single sub-tier supplier producing specialized components can affect hundreds of manufacturers simultaneously. In fact, 80% of supply chain disruptions originate below Tier 1.
The lack of insight beyond Tier 1 suppliers can also lead to ethical issues, which became evident in the cobalt supply chain. Some of the world’s largest brands indirectly sourced cobalt linked to dangerous mining and child labor practices, leading to public backlash, regulatory consequences and a shock to investor confidence.
By better understanding their extended supply networks, businesses can proactively identify hidden risks and respond effectively before potential problems materialize.
10. Why supply chain risk management must start at the product level
When managing risk, many companies focus on direct supplier relationships while overlooking the upstream components and materials essential for their products. By shifting attention to these items, businesses better position themselves to respond effectively to disruptions.
The 2021 semiconductor shortage revealed this weakness on a global scale. Many of the biggest companies in the world depended on semiconductors to produce everything from smartphones to medical devices to automobiles. But in 2021, COVID-19 factory shutdowns, a surge in demand for consumer electronics and geopolitical tensions led to a massive semiconductor shortage.
Companies failed to consider the sub-tier suppliers their products depended on or the overlap of their supply chains with competitors. Even since this shortage, companies still underestimate shared and hidden supplier dependencies by 2–3 times. Organizations need contingency plans to procure alternatives for high-risk, high-demand materials and components.
How to build a more resilient supply chain
Many of the assumptions that shaped supply chain management over the past several decades no longer hold up in today’s volatile geopolitical environment. To succeed, businesses must build resilient supply chains through real-time intelligence while rethinking assumptions that increase their supply chain risk. Organizations that invest in deeper visibility, product-centric risk analysis and continuous monitoring will be better positioned to respond to future disruptions, regardless of where they originate.
One powerful strategy is to focus on product component visibility instead of direct supplier visibility. Sphera’s N-Tier Intelligence solution, part of the Supplier 360 Intelligence family, helps supply chain and procurement leaders trace their components and materials for more nuanced procurement decisions.
