At a Glance
An agreement to end the conflict with Iran and reopen the Strait of Hormuz — expected to be signed this week — is now in jeopardy following Israel's airstrikes on Lebanon. U.S. President Trump warned against derailing the deal, and with Middle East geopolitical risk back in focus, there is growing potential for heightened volatility in global oil prices and in energy, airline, and defense stocks.
Why It Matters Now
The Strait of Hormuz is a critical chokepoint for the world's seaborne crude oil shipments, and whether this passage stays open directly drives the direction of global oil prices. If the deal is reached smoothly, expectations of normalized supply would intensify downward pressure on oil prices; but if the clash between Israel and Lebanon causes the deal to collapse or be delayed, the geopolitical risk premium would persist and oil prices could remain elevated.
Korea relies on imports for nearly all of its crude oil, so developments in the Middle East ripple through to the real economy and the stock market via multiple channels — refining margins, jet fuel costs, inflation, and exchange rates. In particular, when oil prices rise, refiners stand to see improved refining-margin expectations, whereas airlines and shipping firms — for which fuel is a large cost component — face heavier cost burdens.
It is also worth watching that escalating Middle East tensions stoke demand for safe-haven assets, lifting gold prices and the dollar; should this translate into a weaker won, it would have opposing effects on exporters and on import-driven inflation.
Frequently Asked Questions
- Will oil prices rise if the deal falls through — If expectations of a Hormuz reopening recede, supply uncertainty grows and upward pressure on oil prices may prevail.
- Is this a positive catalyst or a negative catalyst for the Korean market overall — Geopolitical risk itself is a driver of greater volatility, but it can present a margin opportunity for certain sectors such as refining, so the impact varies from stock to stock.
- Will it actually get to a signing — The schedule remains fluid given the Israel-Lebanon clash, and markets are expected to react sensitively to news of any progress in negotiations.
- What indicators should I watch besides oil prices — It is useful to track safe-haven flows together, including the won-dollar exchange rate, gold prices, and U.S. government bond yields.
Affected Stocks and Sectors
- S-Oil and SK Innovation — Leading refiners that could see earnings improve if oil prices and refining margins climb.
- GS — An energy holding company directly exposed to shifts in the oil-price environment through its refining subsidiary.
- Korean Air — A leading airline whose high fuel-cost ratio means heavier cost burdens during periods of rising oil prices.
- Hanwha Aerospace — Escalating Middle East tensions can act as a catalyst stoking expectations of defense demand.
- The broader energy and transportation sectors — A structure in which beneficiaries and casualties diverge depending on the direction of oil prices.
Points to Watch When Investing
- Geopolitical news tends to swing between sharp gains (surges) and sharp drops (plunges) on headlines, so short-term momentum-chasing carries significant risk.
- Rising oil prices do not translate directly into refiner earnings; refining margins and inventory-valuation effects must be considered together.
- For airlines and shipping, a cost shock can be amplified if exchange rates and oil prices both turn unfavorable at the same time.
- Because a concluded deal could also trigger a sharp drop (plunge) in oil prices, betting on a single scenario should be avoided.
Overall Outlook
The optimistic scenario is one in which negotiations resume and both the reopening of Hormuz and an end-of-conflict agreement are achieved — oil prices stabilize amid expectations of normalized supply, creating a favorable environment for airline and consumption-related stocks. Conversely, if the clash between Israel and Lebanon escalates into a wider conflict, oil prices could stay elevated, producing a divergence in which refining and defense see short-term benefits while airlines and transportation bear cost burdens. Ultimately, a prudent approach — keeping a close eye on the course of negotiations and the movement of global oil prices while diversifying across sectors — is advisable.
