Trump cancels Iran strike, signals deal as Brazilian Real jumps 1.4%

President Donald Trump scrapped a planned military strike on Iran and said a deal signing was imminent, sending the Brazilian Real to its best day in two months as geopolitical risk premiums collapsed across emerging markets.

President Donald Trump canceled a planned military strike on Iran and said the time and location for signing an agreement would be announced soon, triggering a sharp unwind of geopolitical risk premiums that pushed the Brazilian Real up 1.4 percent against the dollar — its best intraday performance in two months.

"The market is pricing in a genuine de-escalation after months of brinkmanship, and EM currencies are the direct beneficiaries," said Elena Fischer, geopolitical risk analyst at Edgen. "A US-Iran deal removes the single biggest tail risk for oil-importing emerging markets."

The Brazilian Real's 1.4 percent rally marked the currency's strongest single-day gain since April, as traders reduced hedges against a broader Middle Eastern conflict. The move came as oil prices retreated on expectations that a deal could ease supply disruption risks in the Strait of Hormuz, which handles about 21 percent of global crude trade. Safe-haven assets also gave back gains, with gold slipping from recent highs as investors rotated into riskier emerging-market currencies.

The decision to call off military action represents a sharp reversal from just days earlier, when Trump had threatened to strike Iran "very hard" after an Iranian downing of a US Army helicopter. The about-face follows months of on-again, off-again diplomacy mediated by Pakistan, with Field Marshal Asim Munir shuttling between Washington and Tehran. Iran had repeatedly linked progress on any nuclear or regional understanding to a halt in Israeli operations in Lebanon, where its proxy Hezbollah is based — a linkage that complicated earlier ceasefire efforts.

The Lebanon Puzzle

Lebanon has emerged as the critical variable in any US-Iran deal. Iran's Revolutionary Guard Corps has threatened to resume strikes on Israel unless attacks on both Iran and southern Lebanon cease, effectively making Hezbollah's status a veto point on broader diplomacy. A US-brokered ceasefire framework between Israel and Lebanon collapsed earlier this month after Hezbollah rejected terms requiring it to withdraw from southern Lebanon, and Israeli Prime Minister Benjamin Netanyahu has privately dismissed the prospects of US-Iran diplomacy, preferring a return to military operations.

The rift between Trump and Netanyahu over how to handle Iran has widened as both face elections this fall. Trump, contending with high gasoline prices that have become a political liability, has pushed for a diplomatic off-ramp. Netanyahu, facing parliamentary elections and unfulfilled war aims, has resisted constraints on Israeli freedom to operate against Hezbollah.

Stockpile Constraints

The diplomatic shift also comes as the Pentagon confronts a thinning munitions stockpile after months of sustained operations. The US has used an estimated 1,000 or more Tomahawk missiles since the war with Iran began, depleting a pre-war inventory of roughly 3,100, according to a Center for Strategic and International Studies study. Capitol Hill officials estimate the Pentagon needs an additional $20 billion to begin replenishing missile stocks to pre-Ukraine levels. Defense industry leaders were preparing to meet with Trump this week over production shortfalls, with one person familiar with the plans describing the expected discussion as "ugly."

For emerging markets, the calculus is straightforward: a durable US-Iran agreement removes the most significant geopolitical overhang for oil-dependent economies from Brazil to India. The Brazilian Real's rally on Thursday reflects that repricing in real time. The question now is whether the diplomatic window stays open long enough for a deal to be signed — and whether Lebanon's unresolved conflict slams it shut.
