Iran Situation and Today's (April 12) Top 20 Naphtha-Related Japan News

April 12, 2026: Critical News on Naphtha and Petrochemical Raw Materials "Manufacturing, Procurement, and Alternative Technologies"

On April 12, 2026, the Japanese manufacturing and petrochemical industries are reaching a historic turning point. Integrating various economic indicators and market trends released today suggests that the current situation is not merely a "surge in raw material prices" but indicates the "structural limits of an industry based on naphtha."

【Transformation of Manufacturing and Supply Structure】

1. Intentional reduction of naphtha output due to "equipment operation shifts" at domestic refineries According to today's "Refinery Operation Survey" by the Petroleum Association of Japan, domestic refineries are prioritizing gasoline production to maintain social infrastructure, continuing operations that intentionally lower the yield of naphtha as a byproduct. Consequently, domestic naphtha for petrochemical use has entered a state of permanent deficiency.
2. Unstable quality due to "emergency spot purchases" of West African and South American naphtha To compensate for the disruption of Middle Eastern supply, domestic manufacturers have made emergency procurements from Nigeria and Brazil. However, issues regarding chemical compositions (impurity ratios) that do not fit Japanese refining equipment have surfaced, leading to further increases in refining costs.
3. Record expansion of "Naphtha Crack Spreads" in the Singapore market According to market data from this morning, the naphtha crack spread (the price difference between crude oil and naphtha) has reached levels exceeding the turmoil of 2022. This highlights the reality that physical naphtha is in shorter supply than crude oil itself.
4. Distortion of the Asian market due to continued "low utilization rates" at Chinese petrochemical plants While declining naphtha demand in the Chinese market is reported, priority is being given to securing domestic inventories, resulting in a loss of export capacity to Japan. This is a factor driving up spot prices across Asia.
5. Formalization of the "Eastward Route" for North American naphtha and increased costs As an alternative to Middle Eastern sources, naphtha imports from North America (e.g., Paulsboro) are surging. The increased freight costs due to longer transportation distances are pushing up the unit price of naphtha.

【Procurement Risks and Geopolitical Impacts】

6. Hints of export restrictions from South Korean Yeosu and Ulsan petrochemical complexes South Korean manufacturers, major alternative sources for Japan, are continuing to apply "Force Majeure" on exports to overseas markets, including Japan, to prioritize protecting their own domestic manufacturing. Concerns are rising that procurement routes may be completely blocked.
7. 29% decrease in light distillate stocks in Fujairah (UAE) statistics Inventories at a major storage hub decreased by nearly 30% in one week. The avoidance of ports by tankers due to attack risks is causing a "physical severance" of supply.
8. Intensifying "scramble" for non-Russian naphtha in the European market Following drone attacks on Russian refineries, European players are aggressively buying up non-Russian naphtha from Asia and North America, directly impacting Japan's procurement environment.
9. Commencement of demonstration tests for synthetic fuel (e-fuel) alternatives using "Green Hydrogen" Today, a domestic chemical alliance unveiled a pilot plant for "e-plastics" that directly synthesizes plastic raw materials from CO2 and hydrogen without using naphtha. The shift to fully self-sufficient raw materials unaffected by geopolitical risks is accelerating technically.
10. "Disappearance" of naphtha side-streams due to increased Sustainable Aviation Fuel (SAF) production With the decarbonization of the aviation industry, the priority for manufacturing SAF has risen. Naphtha fractions previously obtained as byproducts are being absorbed into SAF production, structurally eroding supply capacity for the petrochemical industry.

【Transition to Alternative Technologies and Post-Naphtha】

11. Risk of supply suspension for nylon raw materials for automotive "tire cords" Chemical companies supplying raw materials to major tire manufacturers such as Bridgestone and Sumitomo Rubber have announced production halts for certain grades due to difficulties in supplying naphtha-derived cyclohexane. The impact on automotive production lines is becoming a reality.
12. Urgent need for alternative development of "photoresist" solvents for semiconductor lithography Specific high-purity solvents refined from naphtha are becoming depleted. Companies like Shin-Etsu Chemical and JSR have launched emergency projects in cooperation with the Ministry of Economy, Trade and Industry (METI) to develop new resist compositions that do not rely on current naphtha-derived components.
13. Automakers present "30% reduction in petroleum-derived materials" targets Major OEMs such as Toyota and Honda have presented reduction targets for petroleum-derived materials to their suppliers. The transition to alternative materials is accelerating by several years, triggered by the naphtha price surge.
14. Improved cost competitiveness of high-performance cellulose materials (CNF) Due to the skyrocketing price of naphtha, the price gap with alternative materials such as Cellulose Nanofiber (CNF), which were previously expensive, is narrowing. Their adoption in structural materials is progressing rapidly.
15. Decarbonization of petrochemical furnaces through "fuel switching" using ammonia and hydrogen As the use of naphtha as a fuel is also being restricted alongside its shortage as a raw material, demonstration experiments to switch petrochemical plant fuel to ammonia are accelerating.

【Broad Industrial Repercussions and Real Economic Impact】

16. 20% rise in synthetic fiber prices and reconsideration of apparel production bases Prices for naphtha-derived polyester and nylon are soaring. Production bases in Southeast Asia are beginning to be reorganized into regions where raw material procurement is easier.
17. "Supply Warning" issued for medical plastic materials Related academic societies have requested the government for priority allocation, stating that securing raw materials for indispensable medical plastics, such as dialysis machines and blood bags, is in jeopardy.
18. Food security risks due to repercussions on chemical fertilizers (urea and ammonia) Supply anxieties for fertilizer raw materials like butane and propane, which are co-products of naphtha, have surfaced. Fertilizer price hikes in the agricultural sector are expected to hit food prices starting this autumn.
19. Delivery delays for "high-purity resins" for semiconductors and electronic components The manufacturing of high-performance resins used in substrates for smartphones and PCs has seen a drop in yield due to "quality instability" of naphtha-derived raw materials, leading to significant delivery delays.
20. "Petrochemical product contribution" to Japan's Consumer Price Index (CPI) reaches maximum According to economic indicator forecasts released today, price increases originating from the naphtha surge are trending higher than the increases in energy itself (gasoline and electricity).
