European stock markets have continued to decline as fears grow over the length of the ongoing conflict in the Middle East. The Spanish stock market has dropped by 0.5%, and oil prices have started to rise again, reflecting the increasing tensions in the region. Investors are now grappling with not just how long the markets can sustain their upward momentum, but also how severely they will be impacted by the ongoing geopolitical strife.

Just two days after US President Donald Trump attempted to calm the markets by suggesting that the conflict was nearing its end, optimism has quickly faded. Companies and investors alike are showing signs of concern as the situation evolves, and market sentiment is deteriorating. The initial hope for a swift resolution has been replaced with a sense of uncertainty about the conflict's duration and potential repercussions on global markets.

Iran's influence in the region could have significant implications for the global economy, particularly with regards to oil supply. The Strait of Hormuz, through which approximately one-fifth of the world's maritime oil supply is transported, has become a pivotal point in these tensions. Iran has expressed its willingness to disrupt shipping through this corridor, which could lead to heightened fears over oil shortages and further fluctuations in global oil prices.
