Trump has announced a 30% tariff on the European Union, starting 1 August. In response, Germany’s Merz plans to work with Macron and von der Leyen to find a solution before the deadline. The EU has paused trade retaliation against the US to allow for more discussions.

Market Reaction

Financial markets reacted to these changes. US equity index futures fell by about 0.5% after the tariff announcement aimed at the EU and Mexico. As of 14 July 2025, the US dollar opened slightly higher in foreign exchange trading. In other news, Trump talked about resolving the tensions in Gaza by next week. He also confirmed plans to send Patriot missiles to Ukraine and suggested that Powell should resign. The markets quickly adjusted, evident in the drop in US equity index futures—around 0.5% lower after the announcement. This indicates that investors are worried about potential economic disruptions, especially fears of escalating trade conflicts between major blocs. The slight rise in the US dollar reflects how quickly currency markets turn to safe havens when trade stability is in question. The announced 30% tariff, effective 1 August, has added uncertainty to transatlantic trade. Traders involved in commodities, industrials, autos, or luxury exports may need to rethink their risk strategies due to increased volatility. The effects of tariffs may go beyond just affected goods, impacting investor confidence and delaying investments, which could affect asset classes previously thought insulated. Volatility in equity curves may continue to rise after mid-July as expectations for actual volatility increase. Merz aims to collaborate with Paris and Brussels, indicating a desire to reduce tensions, but only if there is mutual flexibility. Their response is important and may affect European index options or EUR/USD risk reversals before any policies are enacted. The longer it takes to see concrete developments, the broader the implied volatility may stretch on both sides of the Atlantic.

Impacts on Trading and Policy

The EU’s delay in retaliation offers a brief opportunity to observe market dynamics without the immediate influence of European officials. However, this window may close quickly if deadlines approach without any changes in attitude. Keeping an eye on forward-looking indicators—like skew steepening or shifts in delta hedging costs—can help anticipate corrections or changes in trading products related to DAX or Euro Stoxx derivatives. Meanwhile, distractions from US foreign policy, such as military commitments and personnel discussions, have kept investor sentiments fluctuating. While these issues are not directly tied to the tariffs, they can affect broader investor psychology. Previous instances show that geopolitical comments, especially those linked to monetary policy leadership, can increase implied rate volatility or tighten cross-asset correlations. Trading desks should tighten their alerts on margin thresholds before the August implementation. Short-term contracts may need faster adjustments, especially where trades rely on the current situation remaining unchanged. Open interest on long-term options might only shift when clarity comes from Brussels. Until then, it makes sense to factor in temporary premiums in anticipation of unpredictable moves. Tracking real-money flows from key European sectors will be crucial for assessing risk. Any changes in auto sector ETFs or future freight routes should be monitored closely. A separation between US and European industrials might push pair trades further due to momentum, particularly for those observing the performance of implied-to-realised spreads at the sector level. This presents an opportunity for calendar spreads to increase. We doubt markets will continue to assume balance in fiscal or trade positions through summer unless there’s a significant shift soon.
