LONDON, April 17 - Global financial markets reacted decisively after Iran’s foreign minister said passage for all commercial vessels through the Strait of Hormuz is declared completely open for the remaining period of ceasefire, in line with the ceasefire in Lebanon. The statement triggered a rapid shift in asset prices: oil slumped, government bond yields fell, equities climbed and the dollar lost ground against major peers.
In the immediate aftermath of the announcement, oil prices fell as much as 10% to below $90 a barrel, reflecting the market’s reassessment of a sizable geopolitical supply risk. Short-dated government bond yields tumbled as investors pared back expectations for near-term central bank rate increases, particularly in Europe. Equities rallied across major markets as risk assets were bid higher.
The U.S. dollar, which had been supported as a safe-haven currency since the conflict began in late February, weakened sharply against the euro, the pound and the yen as investors rotated away from safe assets toward riskier positions.
Market reaction and mechanics
Traders and strategists described the moves as a classic re-pricing of risk following a sudden reduction in a major tail risk to global commodity flows. With the prospect of resumed transit through the Strait of Hormuz, the immediate premium in oil prices evaporated, feeding through to other asset classes.
That dynamic was visible across fixed income where short-dated yields fell as markets reduced the probability of urgent rate hikes by central banks. The equity market responded by rotating into sectors that stand to benefit from lower energy costs and a calmer geopolitical backdrop.
Voices from the market
Nick Kennedy, currency strategist at Lloyds in London, said that the market reaction reflected a trajectory that market participants had been anticipating. He commented: "For starters, I don’t think it’s surprising and (talks) has been moving in this direction." He added: "From a markets perspective it’s about the duration of the disruption, so the swifter transit can get through the better, and markets reprice the outlook." On the practical difficulty of trading around such news, he said: "The moves are all in the right direction, it’s just difficult to position for the news and it’s difficult to believe."
Michael Brown, senior research strategist at Pepperstone in London, framed the development as removing a substantial tail risk if transit returns to pre-conflict levels: "It’s all well and good having a ceasefire and we don’t want kinetic action to resume, of course. But during the ceasefire thus far, we’ve still seen the whole Strait of Hormuz remaining impassable. We’ve still had commodity conditions continuing to tighten. If we move to a situation where actually the path is still towards de-escalation - but we now have the bonus of commodity flows through Hormuz getting back to something resembling a normal level that we saw pre-conflict - then that’s obviously removing a pretty chunky tail risk for the economy as well. And I think that’s why markets are reacting so positively."
Lars Skovgaard, senior investment strategist at Danske Bank in Copenhagen, expected the news to be positive but cautioned it would not by itself send markets sharply higher: "I think it will be positive but not something that will propel the market higher. You will most likely see some index rotation, a rebound in leisure names for example, and then we start focussing on earnings. It could lead to outperformance in Europe compared to U.S. and you could see a rebound in emerging markets."
Tom Di Galoma, managing director of global rates trading at Mischler Financial Group in Park City, Utah, attributed the overall market move to the decline in oil: "Oil is falling pretty good here… I think that that’s what’s driving the whole move." He also noted uncertainty about the longevity of the ceasefire and the opening of the strait: "Do we actually get a prolonged ceasefire and a straight opening? I don’t know. This seems like it’s going to take some time to work itself out. But right now, I think that’s what’s going on… It’s all the good news coming out of the Gulf."
Joseph Trevisani, senior analyst at FX Street in New York, emphasised the consistent directional message for markets: "It does all point In the same direction. Nobody in their right mind, and certainly not the administration, trusts anything that Iran says, but actions do matter. Oil is now $86.5. That’s certainly the story today. That’s probably going to weaken the dollar actually. What you’re seeing here is a resolution or a potential resolution that the markets are going to love." He added that the resumption of oil flows would likely reduce some dollar support while noting that interest rate expectations remain a dominant influence on currency moves.
Evelyne Gomez-Liechti, multi-asset strategist at Mizuho in London, described the market’s reception as cautious optimism: "For now, the market is treating it as a step forward." She warned of the risk of a reversal by Iran, saying: "I’m inclined to think that there is still risk that they (Iran) take it (the Hormuz opening) off the table. I think for them one of the main things is, how can they ensure that there won’t be attacks in the future? And they have said several times that that’s one of the big points for them."
On policy implications, Gomez-Liechti noted the likely impact on rate expectations: "It takes the risk of an emergency (central bank rate) hike off the table. There are still a lot of unknowns, but if you have these two parts kind of trying to move a bit closer together. That is positive and just putting myself in the shoes of a central banker, you would prefer to err on the side of caution. There’s already tightening price in the curve. So I think for now, it shifts the narrative more towards holding here and assessing what’s going to happen, rather than keep adding to those hike expectations. So I think we could see the market of shift more towards this holding reaction function for ECB and Bank of England."
Where the effects show up
- Energy markets: The sharp drop in oil prices reflects an immediate reduction in a supply-risk premium tied to the Strait of Hormuz.
- Fixed income: Short-dated yields fell as the chance of emergency rate increases was repriced, especially in Europe.
- Currencies: The dollar weakened as safe-haven demand faded; the euro, pound and yen gained ground.
- Equities: Stocks rose broadly with potential sector rotation into leisure and other consumer-facing names expected to benefit from lower energy costs.
While markets celebrated the development as a reduction in a major near-term risk, several strategists warned that the durability of the ceasefire and the practicalities of reopening the Strait of Hormuz remain uncertain. That lingering doubt underpins continued caution among investors and central bankers as they interpret the policy path ahead.
