The Monday rally: real, rational, and already partially priced in
Global markets advanced strongly on Monday at the start of the week, driven by the US-Iranian agreement on the Strait of Hormuz. S&P 500 1.3%, Nasdaq 2.2%, Stoxx 600 at a new all-time high, Nikkei 5%, Kospi 5.2%. Brent falls 4.8% to $83.15. Bond yields retreat — 10-year Treasuries at 4.45%, Bunds at 2.95%. The euro climbs back above 1.16 dollars. In parallel, SpaceX, which went public on Friday with a 19% jump, adds another 6.8% on Monday, amplifying the positive sentiment on tech.
Three distinct dynamics overlap in this rally, and confusing them would be an analytical error.
The first is geopolitical and energy-related: the Hormuz agreement reduces the risk of persistent inflation, pushes back central bank rate hike expectations, and improves growth prospects for oil-importing economies — Europe and Asia in the lead. This is rational, measurable, and already partially priced in.
The second is monetary: markets are pushing back their rate hike expectations. The Fed is no longer fully priced for a hike before March 2027, versus January expected last Friday. The BoE is pushing back its next hike from November to December. Lower oil mechanically eases the inflationary constraint on central banks — and bond markets have immediately incorporated it.
The third is structural and independent of Iran: the tech rally in Asia, particularly in Japan, reflects a rotation of flows toward AI and semiconductor stocks that predated the agreement. The Nikkei’s all-time high owes as much to Murata Manufacturing ( 18%) and SoftBank ( 10%) as to the drop in oil. Goldman Sachs explicitly identifies the overflow of flows from Korea and Taiwan toward Japan as the main driver — the agreement provided the pretext, not the cause.
For stocks, the rally is as sectoral as it is directional. European cyclicals and industrials ( 2%) directly benefit from improved growth prospects. Energy falls 3% — a mechanical corollary of the drop in oil. In Asia, aviation and transport soar on the prospect of normalizing jet fuel after months of disruptions. For the dollar, the combination of renewed risk appetite and pushed-back Fed rate expectations penalizes it. The euro above 1.16 reflects this dual effect. For gold, the geopolitical risk premium compresses, but real yields retreat simultaneously with falling bond yields — two opposing forces that explain a more moderate gold reaction than pure geopolitical logic would have suggested.
This rally is authentic in its direction, but its speed already incorporates a scenario of complete success of the agreement — demining, commercial reopening, maritime insurance restored, successful nuclear negotiations. Yet as previously analyzed, the agreement holds for 60 days, Israel did not sign, and demining takes at least 30 days. The market is buying the happy ending before seeing the full movie.
The SpaceX case perfectly illustrates the dominant mindset: a spectacular tech IPO in an improving geopolitical context creates a window of euphoria where investors maximize risk exposure simultaneously on multiple fronts. This is institutional FOMO in its purest form — and historically, these windows are shorter than they appear in the moment.
