Wall Street has a short memory for global crises: Morning Brief

The S&P 500 has shown resilience amidst escalating Middle East tensions, remaining largely flat and even gaining 1.0% on Monday following recent US and Iranian actions. Morgan Stanley's analysis of historical geopolitical shocks suggests market sell-offs are typically short-lived, with the S&P 500 averaging gains of 2% within one month and 9% over 12 months. Strategists largely concur that sustained market pain is contingent on a significant oil price spike, specifically WTI reaching approximately $120/barrel (a 75% year-over-year increase) to materially impact stocks, far above current sub-$71 levels. This outlook is reinforced by online betting odds for a Strait of Hormuz closure by July dropping significantly to 11%, mitigating a key global oil supply risk.

Analysis

The US equity market has demonstrated notable resilience to escalating geopolitical tensions in the Middle East, with the S&P 500 remaining largely unchanged since the initial Israeli strike on June 13. Historical analysis from Morgan Stanley, covering over 20 geopolitical shocks since 1950, supports this muted reaction, indicating that such events typically trigger short-lived and modest sell-offs, with the S&P 500 historically gaining an average of 9% in the 12 months following. The decisive factor for a more significant and sustained market downturn is widely seen as the price of oil. According to the research, a substantial negative impact on stocks would likely require WTI crude to surge approximately 75% year-over-year to a level of about $120 per barrel, a stark contrast to its current sub-$71 price. The primary catalyst for such a spike, the closure of the Strait of Hormuz, is now viewed as less probable, with betting market odds for a closure by July dropping from 52% to 11%, suggesting a market perception of de-escalation. While the backdrop of record-high equity indices and rich valuations presents a vulnerability, the immediate geopolitical risk appears contained so long as energy markets remain stable.

Key Decisions for Investors

• Given the historical data suggesting geopolitical sell-offs are transient, investors might consider using any market weakness as a buying opportunity rather than engaging in panic-selling.
• Investors should closely monitor the price of WTI crude oil as the primary risk indicator, with a sustained breach above the $100-$120 per barrel range signaling a potential shift in the market's risk-reward profile.
• Pay close attention to any news or intelligence regarding the Strait of Hormuz, as a renewed threat of its closure would be the most direct catalyst for a destabilizing energy price shock.
• While the immediate threat appears contained, the context of high market valuations warrants maintaining a disciplined approach, as any unexpected escalation or a secondary shock could amplify downside volatility.
