The Ceasefire Arrived — 90 Minutes Before the Deadline

Today’s Core Flow

With 90 minutes left on the US ultimatum, a deal was struck. The US and Iran agreed to a 2-week ceasefire, and markets moved immediately and decisively: the Korean won broke below 1,500 against the dollar for the first time since the pressure began, global equities rallied broadly, Korean government bond yields fell to their lowest level in weeks, and foreign investors returned to the Korean market with heavy semiconductor buying. The relief is genuine. But the deal has an expiration date — two weeks — and the structural inflation pressures that were building before the ceasefire have not been resolved. The next two weeks will determine whether this is the beginning of a durable de-escalation or a pause before another round.

US Economic Landscape

The ceasefire removes — at least temporarily — the primary upside risk to US inflation that has been freezing the Fed’s rate path. If oil prices decline meaningfully and hold lower over the coming weeks, the energy component of CPI will begin to ease. That opens a narrow window for the Fed to re-engage with the rate-cut conversation it had largely shelved.

But the 2-week structure matters enormously. A permanent ceasefire or a peace framework would allow the Fed to plan around sustained lower energy prices. A 2-week truce that may or may not be extended keeps the uncertainty alive. The Fed is unlikely to make any significant policy signal based on a temporary ceasefire alone — it will want to see CPI data confirm the inflation trajectory is actually turning before adjusting guidance.

For now, the ceasefire is doing what markets hoped it would: reducing the tail risk of sustained energy inflation. The question of whether it becomes something more durable is the dominant variable for the weeks ahead.

US Market Reaction

Global equities rallied sharply on the ceasefire news. The relief move was broad-based — risk assets benefited as the war premium embedded in valuations partially unwound. Energy sector stocks gave back some gains as oil prices fell on reduced geopolitical risk premium. Bond yields eased further as inflation expectations moderated.

The Robinhood-BNY Trump accounts partnership adds a structural note to the US market backdrop: government-backed savings vehicles designed for younger investors are being embedded into retail platforms, potentially creating a long-term structural demand for US equities and Treasuries from a new generation of investors. This is a slow-moving story, but one that could influence retail market participation patterns over time.

Korea Impact Analysis

US-Iran ceasefire → oil price decline → KRW breaks below 1,500 → bond yields fall → foreign investors return to Korean equities → semiconductor buying surge

The transmission was fast and clean. USD/KRW dropped below 1,500 — a level that had seemed out of reach just days ago. The 3-year Korean government bond yield fell to 3.315%, its lowest since the inflation pressure intensified. Foreign investors, who had been net sellers for weeks, returned with large-scale net buying concentrated in semiconductors.

Korea’s underlying position going into this moment was stronger than the market stress suggested. February’s current account surplus hit a record $23.2 billion — the largest monthly surplus ever recorded — driven by semiconductor exports that surged 158%. This structural trade strength provides a fundamental anchor for the won, and the ceasefire has allowed that anchor to be recognized by the market.

The shadow over the relief is service inflation. Oil price increases have not yet been fully reflected in dining, travel, and transportation costs — that pass-through was expected to begin this month. Even with the ceasefire reducing future energy price risk, the inflation that was already in the pipeline will still show up in April and May CPI data. The BOK’s April 10 meeting — now Governor Lee Chang-yong’s final meeting before the leadership transition — takes place in a somewhat improved but still complex inflation environment.

There is also a debt warning signal: March household loans increased for the first time in four months, driven by “leverage buying on market crash days.” This is a reminder that financial stability risks can accumulate during volatility periods — and that the BOK cannot afford to fully relax its vigilance even as the macro picture improves.

Today’s Checkpoints

• Ceasefire durability — Two weeks is a defined window; watch for signals of whether negotiations toward a longer-term agreement are underway, or whether the truce is simply buying time
• Oil price trajectory — How far and how fast oil falls will determine whether April CPI data shows meaningful deceleration, which is the key input for the Fed and BOK
• BOK April 10 final statement — Governor Lee’s last meeting; a hold is certain, but the statement may be more cautious than hawkish given the ceasefire improvement — watch for any revision to the inflation outlook language
• Foreign investor flow sustainability — Today’s heavy semiconductor buying is encouraging; whether it continues tomorrow and next week signals whether the “return to Korea” is structural or a one-day reaction

One-Line Conclusion

The ceasefire broke the 1,500 line and reminded markets that Korea’s record current account surplus and semiconductor dominance were always the underlying story — but two weeks is not a resolution, and the inflation already in the pipeline will still arrive.
