War Premium
전쟁 프리미엄
The additional risk premium embedded in asset prices (oil, exchange rates, bonds, and equities) due to geopolitical uncertainty arising from war or military conflict. Because market participants price in the possibility of future supply disruptions preemptively, prices rise even before physical shortages materialize. The war premium is typically largest immediately after the outbreak of hostilities and dissipates rapidly as ceasefire or peace negotiations progress.
In depth
Definition and Mechanism
The war premium is the market's preemptive pricing-in of potential future supply disruptions. Prices rise before physical shortages materialize, driven by market participants' expectations and risk-averse behavior.
The crude oil market is the most classic case. The U.S. Energy Information Administration (EIA) explains that "when there are significant concerns about the potential for a disruption... forward-looking behavior adds a 'risk premium.'" During the June 2025 Twelve-Day War between Israel and Iran, a risk premium of $10–15 per barrel emerged and dissipated within days of the ceasefire.
Manifestation Across Asset Classes
Beyond crude oil, the war premium is observable across multiple assets. In foreign exchange markets, geopolitical uncertainty triggers capital outflows, leading to currency depreciation that becomes entrenched as a "war premium" in exchange rates. In bond markets, safe-haven demand drives up sovereign bond prices and depresses yields. In equity markets, defense and energy stocks benefit while airlines, tourism, and consumer discretionary sectors suffer losses.
Historical Patterns
MCB Group's 2026 study identified a consistent pattern across major supply shocks: the Gulf War (1990–91), the Iraq War (2003), and the Russia-Ukraine war (2022). In each case, the initial price spike was larger than the eventual sustained increase, and markets gradually adapted to new supply equilibria even when conflicts persisted. The U.S. Congressional Research Service (CRS) found that "oil prices, after rising sharply at the outset of the conflict, returned to pre-crisis levels within a few months."
Relationship to Energy Vulnerability
High dependence on critical transit chokepoints like the Strait of Hormuz amplifies the war premium. Economies like South Korea, where more than 70% of crude oil imports pass through a single strait, bear a disproportionately large war premium for the same geopolitical event. This constitutes a core element of the energy vulnerability inherent in comprador monopoly capitalism.
