Tariff 'doom loop' hangs over global equities

Global equities' astonishing rebound since April reflects investor belief that U.S. tariff threats will not fully materialize, leading to elevated valuations despite new levies on partners like the EU and Mexico. However, this market resilience risks creating a 'doom loop' by emboldening President Trump to enact higher tariffs, particularly on the European Union, which represents a larger trade volume than China. Should tariffs exceed current market expectations, growth forecasts would be revised lower, potentially triggering a significant market correction, especially for European equities, as current complacency may be misjudged.

Analysis

Global equity markets, particularly in the U.S., have demonstrated a significant disconnect between bullish performance and escalating trade policy risk. The S&P 500's rally to a new all-time high, representing the second-fastest bear market recovery in 75 years, is fundamentally rooted in investor belief that President Trump's tariff threats are a negotiating tactic that will not fully materialize—a thesis known as the 'TACO' trade ('Trump always chickens out'). This market resilience, however, presents a reflexive risk or a 'doom loop,' where the lack of a negative market reaction to threats, such as the proposed 30% tariffs on the EU and Mexico, could embolden the administration to implement them. Valuations are stretched, with the S&P 500's forward earnings multiple near its highest level in years, increasing vulnerability to a narrative shift. Furthermore, investor focus may be misallocated towards China, while the U.S.-EU trade relationship is larger in total volume ($975 billion vs. $582 billion with China) and represents the second-largest U.S. goods deficit. As noted by Barclays, a 30% tariff on EU goods could trigger a double-digit percentage decline in European equities, a risk that current market pricing appears to discount.

Key Decisions for Investors

• Investors should critically re-evaluate portfolio complacency, as the market's resilience to tariff rhetoric may be creating a feedback loop that increases the probability of actual implementation.
• Monitor U.S.-EU trade developments with heightened scrutiny, as the market appears to be under-pricing the risk of a trade dispute with a partner whose bilateral trade volume exceeds that of China.
• Given stretched equity valuations and high event risk, consider hedging long positions or reducing exposure to companies highly dependent on European and North American supply chains.
• Prepare for increased return dispersion and volatility; active managers may find alpha opportunities in identifying companies insulated from new tariff regimes versus those that are highly exposed.
