The market moved faster than reality on the ground.
A preliminary peace agreement between the United States and Iran, announced Tuesday, sent a quiet tremor through global markets — not with alarm, but with relief. The dollar, long a refuge in times of geopolitical fear, softened as investors turned toward riskier assets, while oil prices eased and equities climbed. Yet beneath the optimism, the world's central banks — in Tokyo, London, and Washington — reminded markets that the consequences of months of conflict do not dissolve with a signature, and that the harder questions about inflation and interest rates remain very much alive.
- A U.S.-Iran peace deal, still light on details, was enough to shift the mood in global markets — fear receded, and money moved accordingly.
- The dollar fell to a 10-day low as its role as a safe-haven currency became temporarily less necessary, while oil prices dropped and equities rallied.
- The Bank of Japan raised rates to a 31-year high as expected, but the yen barely moved — hovering near the psychologically sensitive 160-per-dollar level that has previously triggered intervention.
- Analysts warned that a dovish signal from the BOJ could reignite selling pressure on the yen, making any market stabilization effort increasingly costly.
- The Federal Reserve and Bank of England meet later this week, and traders are watching closely to see whether the end of the conflict arrives in time to ease inflation pressures — or whether months of disrupted energy and supply chains have already set the course.
- Relief was real but cautious: reopening the Strait of Hormuz is a process, not a switch, and the risk of re-escalation, while diminished, has not disappeared.
The dollar slipped to a 10-day low on Tuesday after President Trump announced a preliminary peace agreement with Iran to end the Middle East conflict. Details remained sparse, but markets responded swiftly — oil prices fell, equities rose, and the dollar weakened as investors moved away from safe-haven assets toward riskier bets. The deal would extend an April ceasefire by 60 days and reopen the Strait of Hormuz, which Iran had effectively closed since February.
The yen, however, barely moved. The Bank of Japan raised its benchmark rate to a 31-year high the same day — a decision so widely anticipated it generated no surprise. The currency held near 160 per dollar, a threshold that has previously prompted Tokyo to intervene. Analysts at J.P. Morgan cautioned that any dovish tone from the BOJ could reignite selling pressure on the yen and Japanese government bonds, complicating efforts to stabilize markets.
The larger test arrives later in the week, when both the Bank of England and the Federal Reserve are scheduled to meet. Traders are asking whether the peace deal came soon enough to meaningfully ease inflation — energy prices have been elevated for months, and supply chains remain strained. The dollar index sat at 99.66, still up 2 percent since the conflict began in late February. The Australian dollar hovered at $0.7061 ahead of its own central bank decision, with analysts warning the currency could fall if the RBA signals concern about growth.
Analysts at ING tempered the optimism, noting that restoring normal shipping through the Strait of Hormuz would require safe, predictable, and insurable conditions — none of which are guaranteed. Depleted reserves would need replenishing, and re-escalation risks, while reduced, had not vanished. The currency reaction remained muted compared to other asset classes, as traders waited for central bankers to speak. The relief was genuine; the clarity was not.
The dollar slipped to its lowest point in ten days on Tuesday as word of a preliminary peace agreement between the United States and Iran rippled through global markets, lifting investor appetite for riskier bets. President Trump announced that a deal to end the Middle East war had been signed, though specifics remained under wraps. That didn't matter much to traders. Oil prices fell, equities rose, and the dollar—traditionally a safe harbor during geopolitical turmoil—weakened as money flowed toward assets that thrive when fear recedes.
The yen, meanwhile, barely budged. The Bank of Japan had raised its benchmark interest rate to a 31-year high on the same day, a move so thoroughly expected that it generated no market surprise. The yen held steady around 160 per dollar, a level that has made Tokyo nervous enough to intervene before. Analysts at J.P. Morgan noted that even the peace deal offered little comfort for the battered yen. If the BOJ's next communication sounded dovish—if officials suggested they might pause their rate-hiking campaign—it could reignite selling pressure on the currency and Japanese government bonds, making any effort to stabilize markets increasingly expensive.
The real test comes later this week. The Bank of England and the Federal Reserve are both scheduled to meet, and traders want to know whether the end of the conflict has arrived too late to matter for inflation. Energy prices have been elevated for months. Supply chains have been disrupted. The question now is whether those pressures will fade quickly enough to change the calculus on interest rates, or whether central banks will feel compelled to keep tightening. The dollar index, which measures the greenback against six other major currencies, sat at 99.66, up 2 percent since the conflict first erupted in late February.
The Australian dollar was trading at $0.7061 ahead of its own central bank decision. The Reserve Bank of Australia is expected to hold rates steady after three consecutive increases, even as inflation remains stubbornly high. Analysts at Commonwealth Bank of Australia warned that the Aussie could fall further if the RBA signals growing concern about economic growth, prompting markets to abandon bets on additional rate hikes. The euro was just below its ten-day high at $1.159, and sterling bought $1.3413 in early trading.
But beneath the initial market euphoria lay genuine uncertainty. The U.S.-Iran agreement would extend a ceasefire announced in April for another 60 days and reopen the Strait of Hormuz, which Iran had effectively closed since the U.S. and Israel attacked Iranian targets in February. Energy markets moved quickly to price out the risk of prolonged supply disruptions, but analysts at ING cautioned that the path back to normal flows remained anything but straightforward. Shipping through the strait would need to be safe, predictable, and insured. Depleted reserves would need replenishing, likely driving demand higher than usual. Re-escalation risks had diminished but not disappeared. Market analyst Tony Sycamore at IG noted that the currency reaction had been muted compared to other asset classes, as traders waited to hear from central bankers around the world. The immediate relief was real, but the longer-term picture remained clouded by questions about inflation, interest rates, and whether this fragile peace would hold.

Why did the dollar weaken if peace is usually good for the world economy?
Because peace reduces the flight to safety. When geopolitical risk drops, investors move money out of dollars and into riskier assets—stocks, emerging market currencies, commodities. The dollar is the default hiding place when things look scary. When they don't, it loses that appeal.
But the Bank of Japan just raised rates. Shouldn't that have strengthened the yen?
You'd think so. Higher rates usually attract money. But the yen is trapped. It's at 160 per dollar, a level that makes Tokyo nervous about intervention. If the BOJ sounds like it might pause, the selling pressure could be brutal. The peace deal doesn't change that structural problem.
What's the real story here—the peace deal or the central banks?
The central banks. The peace deal is the headline, but what traders actually care about is whether inflation is finally cooling enough for central banks to stop raising rates. If it is, everything reprices. If it isn't, the relief is temporary.
Is the Strait of Hormuz actually going to reopen smoothly?
That's the bet everyone's making, but it's not certain. Supply chains are fragile. Reserves are depleted. Even if shipping resumes, demand could spike as countries restock. And re-escalation is still possible. The market moved faster than reality on the ground.
So this peace deal might not actually change much?
Not immediately. Oil prices fell, which is real. But the inflation damage from months of disruption is already baked in. The question is whether central banks believe the worst is over. If they don't, they keep tightening, and the dollar stays under pressure. If they do, everything shifts.
