LIFEFUND股份有限公司主要在靜岡縣濱松市提供新建住宅。由於 نفت短缺，建築業受到影響的擔憂正在加劇。
LIFEFUND股份有限公司（所在地：靜岡縣濱松市中央區，代表：白都卓磨）向正規劃購屋的民眾發布警示資訊，說明自2026年3月起日益嚴峻的 نفت危機對住宅建材造成的影響。
什麼是 نفت危機？為何與蓋房子有關？
從海外運送物資到日本的油輪示意圖。
2026年2月底，美國、以色列與伊朗之間的軍事衝突，導致中東能源運輸的關鍵咽喉——荷姆茲海峽事實上遭到封鎖。
日本約9成的原油進口依賴中東地區。這次封鎖不僅影響汽油和電價。許多住宅建材，如斷熱材、管材、塗料等，其原料是從石油精煉過程中得到的「 نفت」。隨著 نفت的採購開始出現停滯，住宅建材也開始受到直接影響。
對住宅建材的影響
面對 نفت供應的不確定性，大型化學製造商（如三菱化學、三井化學、旭化成等）接連宣布減產乙烯設備。為此，住宅建材製造商也紛紛調漲價格。

常見問題
What is the naphtha crisis?
The naphtha crisis refers to the disruption and price increase of naphtha, a key petroleum-derived raw material, caused by geopolitical events such as the closure of the Strait of Hormuz. This impacts the production of various materials, including those used in housing construction.
How does the naphtha crisis affect housing construction?
Many housing materials, like insulation, piping, and paints, are made from naphtha. Supply shortages and price hikes for naphtha lead to increased costs and potential delays in the availability of these building materials.
What specific housing materials are affected?
Key affected materials include insulation (e.g., Kaneka Foam, with a reported 40% price increase) and piping materials (e.g., Vinyl Chloride Resin, with a reported increase of 30 yen/kg or more).
What should people planning to build a home do?
It is advisable to consult with your construction company about potential impacts on material availability and costs. Planning ahead, understanding potential delays, and discussing alternative materials or construction timelines with your builder are recommended.
When did this crisis begin to impact the market?
The article indicates that the naphtha crisis has been intensifying since March 2026, with price increases for materials announced effective from April 1, 2026.
