Middle East Crisis In Focus: Second-Order Risks Across The Taiwan Strait

The outbreak of the Israel/US-Iran conflict in early 2026 is not only a Middle East story. For risk professionals, procurement leaders and boards with global supply chain exposure, the war has crystallized into the defining geopolitical stress-test of the decade. Consequences stretch deep into East Asia and, critically, into the potential for geopolitical turmoil in Taiwan.

The immediate supply chain damage is severe. Iran's closure of the Strait of Hormuz has disrupted 20% of global oil supply and significant volumes of LNG; approximately 84-87% of this was destined for economies in Asia. For procurement and TPRM functions, this is now an active disruption cascading through Tier 1, 2 and 3 supplier networks simultaneously.

Beyond energy, the conflict has exposed a striking concentration of industrial input risk. Qatar's Ras Laffan complex, responsible for roughly 20% of global LNG and 30% of global helium supply, has been critically affected. Helium is a non-negotiable feedstock for semiconductor manufacturing. Sulphur, meanwhile, underpins fertilizer production and copper refining – and half of global seaborne trade transits the Strait. Aluminium output from the Gulf has collapsed following strikes on Emirates Global Aluminium, triggering shortages across automotive, aerospace and packaging sectors. Under similar strain, tungsten prices have surged over 50% since March 2026 alone.

The Taiwan Dimension

Helium, sulphur, aluminium and tungsten are all critical resources for advanced electronics, which brings us to Taiwan. For organizations with supply chains running through the country – particularly in the semiconductor space – the Iran conflict raises an urgent second-order question: does the war increase the probability of Chinese action against Taiwan? If so, does it narrow the window for supply chain diversification?

The answer is nuanced. China appears to be reacting to the crisis by leveraging its buffer of strategic crude oil reserves to observe how US military resources are stretched and how maritime economic pressures translate into strategic outcomes. Indeed, the Hormuz situation provides China with a live case study for a potential ‘quarantine’ of Taiwan, rather than a full naval blockade. This would entail a campaign of insurance pressure, grey-zone harassment of commercial shipping, and cyber attacks on port and terminal infrastructure.

Taiwan's energy vulnerability renders this playbook powerful: as of May 2025, Taiwan's grid depends on imported fossil fuels for 83% of power generation. President Lai Ching-te has already announced plans to restart nuclear facilities at Guosheng and Maanshan in response, acknowledging that energy is – as a 2025 CSIS report put it – "the weakest element" of Taiwanese resilience.

Implications For TPRM And Supply Chain Risk Functions

For risk managers, this dual-theatre dynamic demands an immediate uplift in geopolitical risk integration across TPRM and risk intelligence programmes. Verdantix identifies three priorities:

1. Expand supplier mapping beyond Tier 1.
   The helium, sulphur and aluminium shocks of March 2026 are Tier 2 and Tier 3 exposure failures. Organizations with semiconductor or electronics exposure need urgent visibility into which sub-tier suppliers depend on Gulf-based industrial inputs, LNG that transits the Strait of Hormuz, or Qatari feedstocks.
2. Stress-test Taiwan concentration in technology supply chains.
   Any firm sourcing advanced logic chips, substrates or packaging from Taiwan without a credible buffer strategy is carrying unpriced geopolitical risk. The Iran conflict has accelerated the timeline for boards to demand scenario analysis on a Taiwan supply disruption.
3. Monitor the Washington-Beijing dynamic closely.
   The US arms deal with Taiwan remains suspended pending diplomatic engagement between Washington and Beijing. China's decision to encourage Iranian participation in April negotiations could suggest that Beijing is trading geopolitical cooperation for concessions on Taiwan. TPRM teams should treat this diplomatic channel as a leading risk intelligence indicator: any breakdown raises risk premiums materially.

The Israel/US-Iran conflict has done what years of risk framework discussions could not: it has rendered concrete the interconnectedness of energy security, maritime chokepoints, industrial input concentration and geopolitical rivalry. Pressure-testing supply chain resilience against all of these critical points is the only way to plan for simultaneous and second-order shocks. Ultimately, supply chain and risk functions must watch closely and plan carefully, or they will leave themselves exposed.
