RUSSIA-UKRAINE WAR IMPACT

Buffered Oxide Etch (BOE) Market Had a Negative Effect Due to Delays in Logistics and Higher Transportation Prices During the Russia-Ukraine War

The Russia-Ukraine war has adversely impacted global supply chains and this has impacted the Buffered Oxide Etch (BOE) market growth that is dependent on the raw materials and specialized chemicals generally supplied by global means. Sanctions imposed on Russia and the lack of stability that the region faces, have created a delay in logistics, higher transportation prices, and decreasing supply of semiconducting grades of materials. Furthermore, the volatility of the prices of energy has risen manufacturing expenses of the BOE producers owing to Europe inadvisably banking on Russian energy. These have constrained the profit margins and down-drawn the manufacturing schedules in major semiconductor centers. However, the trend to diversify the supply and augment domestic production in such regions as Asia and North America are slowly bringing equilibrium to the market dynamics.
