Why global markets are brushing off U.S. strikes on Iran

Global markets reacted with surprising restraint to U.S. strikes on Iranian nuclear facilities, with the MSCI World index experiencing only a minimal decline, as investors and strategists largely perceive the conflict as contained and potentially reducing regional nuclear threat. While the primary market concern revolves around Iran's potential closure of the Strait of Hormuz, experts widely dismiss this as improbable, citing historical non-action and the likelihood of severe U.S. retaliation. This outlook has led some analysts to maintain a bullish stance on the U.S. market, viewing the events as re-establishing American deterrence.

Analysis

Global markets have exhibited a muted and surprisingly risk-on response to the U.S. strikes on Iranian nuclear facilities, a development strategists largely perceive as contained rather than a systemic threat. The MSCI World index saw a negligible decline of 0.12%, while traditional safe-haven assets displayed mixed to weak performance; spot gold slipped 0.23% and the Japanese yen weakened 0.64% against the U.S. dollar, which saw its index rise 0.35%. According to analysts like Dan Ives of Wedbush, the market views the event as a net positive, believing it has removed a significant nuclear threat and is unlikely to escalate regionally. The primary forward-looking risk centers on Iran's potential closure of the Strait of Hormuz, a critical channel for 20 million barrels of daily oil trade. However, market participants and strategists such as Marko Papic of GeoMacro Strategy assess this as a highly improbable scenario, citing Iran's history of empty threats and the credible deterrent of a severe U.S. retaliatory strike. This perceived re-establishment of U.S. military deterrence has reinforced bullish sentiment for some, with Yardeni Research maintaining a 6,500 target for the S&P 500 by the end of 2025, framing the geopolitical event as a support for the ongoing U.S. bull market.

Key Decisions for Investors

• Given the market's interpretation of the conflict as contained, investors could consider maintaining a risk-on posture, as the removal of a perceived nuclear threat and re-established U.S. deterrence are seen by some analysts as bullish for U.S. equities.
• The primary tail risk remains a potential Iranian blockade of the Strait of Hormuz; investors should closely monitor any credible signals of escalation in this area, as this would rapidly invert the current market thesis and trigger a sharp sell-off in equities and a spike in oil prices.
• Re-evaluate positions in traditional safe havens, as the current dynamic of a strengthening U.S. dollar and diminished geopolitical fear premium is creating headwinds for assets like gold and the Japanese yen.
