Right now, oil prices are deciding the fate of the Korean economy. On day 8 of the Iran War, WTI crude oil futures surged 8.51% in a single day, breaking through the $81 per barrel mark. JPMorgan warned that prices "could soar to $120–130 if the Strait of Hormuz is fully blockaded."
TL;DR
- WTI April futures closing price: $81.01/barrel (+8.51%)
- Domestic gasoline national average: surpassed ₩1,800/liter (Seoul exceeded ₩1,900)
- Bank of Korea's 2026 oil price assumption: $64/barrel → already more than 20% off
- JPMorgan worst-case scenario: $120–130/barrel (if Hormuz is fully blockaded)
- President Lee Jae-myung: directed preparation of a fuel price cap system
1. The Facts: WTI $81 — What Happened?
Eight days after the U.S.–Israel airstrikes on Iran (February 28), Iran's Islamic Revolutionary Guard Corps (IRGC) has effectively implemented a blockade of the Strait of Hormuz. With roughly 20% of global crude oil shipments passing through this chokepoint now blocked, WTI futures prices have been surging sharply since the war began.
- WTI April contract closing price on March 6: $81.01 (+8.51% from the previous session)
- Brent crude surged in tandem at a similar level
- Iraq and Kuwait: no alternative sea routes outside Hormuz
- Escalation premium compounded by the variable of Kurdish ground operations
KB Securities analysis: "As the Iran situation shows signs of prolonged conflict, the energy market has moved beyond short-term volatility and entered a zone of structural risk."
2. Why Is the Price Rising So Fast?
① Immediacy of the supply shock — Once the Hormuz blockade became a reality, markets responded instantly. By the nature of futures markets, even the fear of supply disruption is priced in preemptively.
② No alternative routes — Iraq and Kuwait have no export routes other than Hormuz. The only bypass is the UAE's Abu Dhabi–Fujairah pipeline (ADPCo), which is precisely why Korea secured 6 million barrels of crude through an emergency agreement with the UAE.
③ Kurdish ground offensive joins the fray — President Trump expressed "total support" for Kurdish forces advancing into Iran, heightening fears of escalation. If a ground war materializes, destruction of Iran's oil infrastructure and retaliation are expected.
④ Speculative demand — Capital is flooding rapidly into energy-related ETFs and futures. "War theme" investing, coupled with a simultaneous surge in defense stocks, is accelerating the oil price rally.
3. Context: Why Is Korea Especially Vulnerable?
Korea relies on imports for about 94% of its crude oil, with Middle Eastern sources accounting for over 70%. This is why the KOSPI suffered its worst single-day plunge since 9/11 — a 12% collapse.
| Indicator | Bank of Korea Baseline | Current Market Conditions |
|---|---|---|
| WTI Oil Price | $64/barrel | $81+ (already +26%) |
| Consumer Price Inflation | 2.2% | Holding at 2.0% (upside risk) |
| Economic Growth Rate | 2.0% | Uncertainty expanding |
| KRW/USD Exchange Rate | — | Around ₩1,465 (briefly reached ₩1,507) |
ING analysis: The oil price shock could add 0.2–0.4 percentage points of additional upward pressure to Korea's CPI. The 2026 outlook has been revised upward from 2.0% to 2.2%.
4. Outlook: 5 Warning Scenarios
⚠️ Warning 1: Risk of the 2% Inflation Defense Line Breaking
The Bank of Korea has officially warned of upward pressure on March inflation. If oil prices exceed $90, achieving the annual inflation target becomes virtually impossible.
⚠️ Warning 2: Rate Cut Scenario Evaporates
Rising inflation reduces the Bank of Korea's room to cut rates. Simultaneously achieving domestic demand recovery and interest rate normalization becomes extremely difficult.
⚠️ Warning 3: Direct Hit to Household Real Income
We are now in an era of ₩1,800 gasoline and ₩1,832 diesel. Since prices exceeded ₩1,900 in Seoul, the number of households seeing fuel costs rise 30–40% compared to 2024 is growing.
⚠️ Warning 4: JPMorgan's $120–130 Scenario
If the full Hormuz blockade persists for more than two weeks, $120–130 per barrel could become a reality. In that case, domestic gasoline prices breaking through ₩2,500 per liter cannot be ruled out.
⚠️ Warning 5: Compounding Effect of a Weak Won
Rising oil prices trigger a vicious cycle: worsening current account → weaker won → further rise in import prices. If the exchange rate re-enters the ₩1,500 range, the shock will be amplified.
