Spain's Ibex index achieved record levels, touching 18,450 points during trading, despite a backdrop of confusion caused by legal challenges to Donald Trump's authority to impose tariffs at will. The index closed with a gain of half a percent, marking a new high just below 18,300. The spike in the Ibex stands out particularly as the US markets and dollar weakened, showcasing a stark contrast in performance between these markets.

Investor sentiment towards gold improved, leading to a more than 2% increase in its price, as the metal is viewed favorably as a safe-haven asset. This trend aligns with the upward movement in the Ibex, which is primarily influenced by its banking sector, with major banks like Santander, Sabadell, and Telefónica witnessing significant gains. The overarching economic uncertainty, particularly regarding Trump's trade policies, has created a mixed market landscape, yet the Ibex remains buoyant.

The reaction of the markets to Trump's tariff issues reflects broader implications for trade policies and international economic relations. Legal challenges to Trump's superpowers over tariffs mark a critical point that could influence longer-term strategies of investors and companies alike. As Spain's main stock index leads amidst declines in major global equity markets, it signals potential resilience and a favorable investment climate within the country, despite surrounding global uncertainties.
