US-Iran: Markets Await a Suspended Truce

US-Iran: Markets Await a Suspended Truce

Stocks rally, oil falls and gold remains supported: the announced deal is still fragile without a formal signature.

After weeks dominated by the risk of a global energy shock, markets have suddenly shifted scenario. On Sunday, June 14, a preliminary agreement between the United States and Iran was announced to halt hostilities, reopen the Strait of Hormuz and launch a broader negotiation process on the nuclear dossier and sanctions. But the decisive step is still missing: the formal signature.

It is precisely this gap between political announcement and final agreement that keeps the picture unstable. Markets, overnight between Sunday and Monday, June 15, reacted enthusiastically to the prospect of de-escalation. Asian equities rose sharply, US futures posted significant gains, oil fell abruptly and bond yields moved lower. However, beneath the surface of the rally, one crucial question remains: is the market pricing in a peace already secured, or only a still-vulnerable truce?

The draft agreement appears economically significant. The central point concerns Hormuz, the strategic passage through which an essential share of the world’s oil and liquefied natural gas supply transits. Reopening the Strait would immediately reduce the geopolitical premium embedded in crude prices. It is no coincidence that Brent fell decisively toward the $83-per-barrel area, moving away from the peaks reached during the most acute phase of the crisis.

For the oil market, the message is clear: if Hormuz remains open, the catastrophic scenario is postponed. Oil is no longer pricing in imminent physical scarcity, but a gradual normalization of flows. In this context, Brent moving down toward the $80 area would be consistent with a return to stability in trade routes and with lower pressure on insurance premiums, freight rates and logistics costs.

The reaction from equity markets confirms this interpretation. Investors bought risk because lower oil prices reduce inflationary pressure, ease pressure on central banks and improve the outlook for corporate margins and consumer spending. The sectors most favored are those that had suffered the most from the energy shock: transport, airlines, industry, technology, discretionary consumption and Asian markets that import energy.

The Nasdaq, in particular, benefits from a double tailwind. On the one hand, lower yields make growth-stock valuations more attractive again. On the other, the artificial intelligence theme continues to represent the main structural driver of the US market. If oil stops being an immediate inflationary threat, the narrative quickly shifts back to earnings, technology and liquidity.

Europe also reacted positively, but with greater caution. Futures on the DAX and Euro Stoxx posted significant gains, supported by the prospect of cheaper energy and lower pressure on industrial costs. However, Europe remains more vulnerable than the United States to any renewed flare-up of the crisis, both because of its greater energy exposure and because of the less technology-driven structure of its equity market.

The most interesting move concerns gold. In theory, a peace agreement should reduce demand for safe-haven assets. Instead, the precious metal rose. The explanation is macroeconomic: falling oil means lower inflationary pressure, and therefore a lower probability of further monetary tightening. The decline in yields and the weakening of the dollar supported gold, which also remains underpinned by structural factors such as geopolitical fragmentation, fiscal risk and long-term demand for protection.

The real point of fragility remains the Lebanese front. Israel is not part of the US-Iran agreement and has continued to claim operational freedom against Hezbollah. The raids on Beirut have already triggered a strong Iranian reaction and highlighted the central problem of the agreement: for Tehran, the stabilization of Lebanon is not a separate dossier, but an essential component of any regional settlement.

This makes the scenario very different from a classic diplomatic peace. We are not facing a fully signed, ratified and implemented agreement, but a political memorandum that still needs to be consolidated. The market has chosen to anticipate the positive scenario, but the sustainability of the rally will depend on three conditions: the effective signing of the agreement, the safe and verifiable reopening of Hormuz, and the cessation or at least significant reduction of operations in Lebanon.

For the coming sessions, therefore, the key assets to monitor remain oil, gold, the dollar and bond yields. If Brent continues to move down toward the $80 area, equities could extend their recovery, with potential outperformance from technology, cyclicals, industrials and energy-importing markets. If, instead, crude were to quickly return above $90, it would signal that the market is reconsidering the risk of only a partial or unstable reopening of Hormuz.

The positive scenario assumes a formal signature within a few days, a reduction of tensions in Lebanon, the gradual normalization of maritime traffic and a decline in oil toward $75-80. In that case, equity indices could extend the upward move, with Nasdaq and S&P 500 supported by yield compression and the recovery of risk-on sentiment.

The intermediate scenario, perhaps the most realistic today, is that of a fragile truce: agreement announced, signature delayed, Hormuz partially normalized and Israel still active in Lebanon. In this case, markets could remain positive but highly sensitive to news flow, with oil fluctuating between $80 and $90, gold supported and equity indices exposed to sharp profit-taking.

The negative scenario would return if the signature failed, if Iran judged US guarantees on Israel to be insufficient or if new attacks in Lebanon triggered a broader response. In that case, the overnight rally would be quickly scaled back. Oil could recover its geopolitical premium, the dollar could strengthen again, yields could move higher and equity indices could correct after the initial excess of optimism.

In conclusion, the market welcomed the announcement of the US-Iran agreement as a potentially decisive turning point. The reaction was clear: more equities, less oil, more bonds, a weaker dollar and gold supported by falling yields. But the game is not yet over. The difference between an announced agreement and a signed agreement remains substantial.

For investors, the message is clear: the catastrophic risk around Hormuz has decreased, but it has not disappeared. Volatility in the coming sessions will depend on the ability of diplomacy to turn an announcement into an operational agreement. Until then, the rally remains credible but fragile, supported by relief and threatened by geopolitics.
