- 01Assess switching costs: Before accepting a below-market deal, calculate the long-term cost of switching suppliers. If it's high, the discount may not be worth it.
- 02Diversify sources: Maintain relationships with multiple suppliers, even if they are slightly more expensive. Redundancy is insurance against dependency.
- 03Invest in flexibility: Design infrastructure to handle multiple input types. This may cost more upfront but reduces vulnerability.

The Strategy Behind Below-Market Prices
When Saudi Aramco sells crude oil at a discount to refineries in Asia, it's not a loss leader—it's a calculated move to create dependency. Since the 1990s, Aramco has offered contracts to refineries in South Korea, Japan, and India at prices below the global benchmark. The catch? The crude is heavy and sour, requiring specialized infrastructure to process.
Refineries that accept these contracts must reconfigure their entire operation—distillation units, desulfurization equipment, and storage tanks—to handle this specific type of oil. After several years of running on heavy Arab crude, the facility becomes optimized for that feedstock. Switching to a different supplier would require a costly retrofit, often running hundreds of millions of dollars. The discount, in effect, becomes a technical handcuff.
Dependency Engineering: A Broader Playbook
This pattern isn't unique to oil. China employs the same strategy with rare earth elements—a group of 17 metals essential for electronics, magnets, and defense systems. China controls a significant share of global rare earth production and has historically sold them at competitive prices. This encouraged manufacturers worldwide to build supply chains dependent on Chinese exports.
In 2010, during a diplomatic dispute with Japan, China halted rare earth exports. Japanese companies had no immediate alternatives, as building new mines and processing facilities takes years. The move demonstrated how a supplier can weaponize dependency.
How the Trap Works
Dependency engineering follows a predictable sequence:
- Enticement: A dominant supplier offers a product at a below-market price, making it economically irrational for buyers to refuse.
- Adaptation: The buyer invests in infrastructure, processes, or supply chains tailored to that specific product. Over time, switching costs become prohibitive.
- Lock-in: The buyer's operation is now dependent on the supplier. The supplier can then raise prices or restrict supply without fear of losing the customer.
The initial discount is not generosity—it's the first installment of the trap. Once the buyer is locked in, the supplier's pricing power has no ceiling.
Practical Takeaways for Businesses and Policymakers
- Assess switching costs: Before accepting a below-market deal, calculate the long-term cost of switching suppliers. If it's high, the discount may not be worth it.
- Diversify sources: Maintain relationships with multiple suppliers, even if they are slightly more expensive. Redundancy is insurance against dependency.
- Invest in flexibility: Design infrastructure to handle multiple input types. This may cost more upfront but reduces vulnerability.
- Monitor geopolitical risk: Suppliers in politically unstable regions or with strategic state control can change terms abruptly.
The Bigger Picture
Dependency engineering is a form of economic warfare that exploits the buyer's short-term greed. By understanding the mechanics, individuals and organizations can recognize the trap before they are caught. The key is to look beyond the immediate price and evaluate the total cost of dependence.

Frequently asked questions
Why does Saudi Aramco sell oil below market price?+
Saudi Aramco offers discounts to lock buyers into long-term dependency. Refineries that process heavy Arab crude must invest in specialized infrastructure, making it costly to switch suppliers later. Once locked in, Aramco can raise prices without losing customers.
How does China's rare earth strategy mirror Saudi Aramco's?+
China controls a large share of global rare earth production and sells them at competitive prices to encourage global dependence. In 2010, China cut off supply to Japan during a dispute, demonstrating how dependency can be weaponized. Both strategies involve creating high switching costs for buyers.
What is dependency engineering?+
Dependency engineering is a strategy where a supplier offers attractive initial terms to entice buyers, who then invest in infrastructure tailored to that supplier. Over time, switching becomes prohibitively expensive, giving the supplier pricing power and control.
Can a company escape the discount trap?+
Yes, by diversifying suppliers, designing flexible infrastructure, and calculating total switching costs before accepting below-market deals. Proactive planning reduces vulnerability to dependency.
Is selling below market price always a trap?+
Not always. Some discounts are genuine promotions or responses to market conditions. The key is to assess whether the deal creates high switching costs or locks the buyer into a specific supplier's product.
How can policymakers protect against dependency engineering?+
Policymakers can encourage domestic production, stockpile critical materials, and promote international agreements that ensure supply diversity. They should also monitor strategic sectors for over-reliance on single suppliers.
