A new report highlights a critical vulnerability for the Korean economy: rising oil prices driven by geopolitical conflict.
The Korea Institute for Industrial Economics & Trade (KIET) recently estimated that a 10% jump in crude oil prices leads to a 0.71% increase in average manufacturing costs. This isn't just a theoretical exercise. The U.S.-Iran war has already pushed oil past $100 a barrel, primarily by disrupting traffic through the Strait of Hormuz, a vital artery for global energy.
The causal chain for this shock is clear and swift. First, direct conflict and attacks on infrastructure, like the strike on a Saudi Aramco facility, created immediate supply fears. Second, this led to a near-total halt of shipping through Hormuz, which physically constrained supply and sent prices soaring. Brent crude quickly jumped to over $100.
The impact on Korea was immediate. The KOSPI plunged, and the Korean won weakened to a 17-year low near 1,500 per dollar. A weaker won is a double-edged sword, as it makes Korea's exports cheaper but also makes crucial imports, like oil, much more expensive. This amplifies the cost pressures KIET identified.
To counter this, the International Energy Agency (IEA) announced a historic release of 400 million barrels from emergency reserves. However, this action only tempered the worst-case fears rather than solving the underlying physical bottleneck at Hormuz.
This situation puts the Bank of Korea in a tight spot. Before the conflict, inflation was manageable at around 2%. Now, it faces cost-push inflation—where prices rise due to higher input costs, not strong demand. Raising rates to fight this inflation could stifle an already soft economy, but not acting could risk instability. The KIET report thus serves as a stark warning of the stagflation risks ahead.
- Glossary
- Strait of Hormuz: A narrow waterway connecting the Persian Gulf to the open ocean, through which about one-fifth of the world's oil supply passes.
- Cost-push inflation: Price increases caused by a rise in the costs of production, such as wages or raw materials.
- Stagflation: A period of slow economic growth and relatively high unemployment—or economic stagnation—accompanied by rising prices (i.e., inflation).
