Instability in the Middle East is driving up crude oil prices and increasing the cost of cooking oil and fish in Japan [1].
These price hikes impact daily household expenses and highlight the vulnerability of the Japanese food supply chain to geopolitical volatility. The cost increases stem from a combination of rising fuel prices and the cost of petroleum-derived packaging materials [1, 5].
Experts indicate that the impact of these price shifts often takes time to reach the consumer. Specifically, there is a one-year time lag before the full effects of these cost increases manifest in retail prices [1]. Some product price increases were already expected to begin in May 2024 [3].
Cooking oil is particularly susceptible to these fluctuations. While oils are typically derived from soybeans or rapeseed, they can also be processed into biofuels [2]. As crude oil supply concerns grow, the demand for these oils as fuel increases, reducing the supply available for food and driving up prices [1, 5].
Seafood is also affected due to the rising cost of fuel for fishing vessels and the petroleum-based materials used for packaging and transport [1]. The broader agricultural sector is feeling the pressure as instability in oil-producing regions creates ripple effects across the supply chain [5].
"Middle East affairs are affecting the prices of various foods," said caster Mitsuki Takayanagi [1]. Reporter Sae Izumi said that cooking oil, made from soybeans and rapeseed, can also be used as biofuel [2]. An expert via Yahoo! News said that anxiety over crude oil supply is beginning to spread into the agricultural sector [5].
“The impact of these price shifts often takes time to reach the consumer.”
The situation demonstrates how energy insecurity directly translates into food insecurity. Because cooking oil serves as a dual-purpose commodity for both nutrition and fuel, it acts as a primary transmission mechanism for oil price shocks to hit the consumer's dinner table. The identified one-year lag suggests that current geopolitical tensions will continue to pressure Japanese food inflation well into the future.
