Global markets experienced a tumultuous week characterized by significant political and economic pressures, resulting in collective losses for stock indices on Wall Street.

Investor apprehensions regarding the U.S. economy's health were heightened amid ongoing debates about debt levels and budget deficits, alongside escalating trade tensions between Washington and its partners, particularly following President Trump's threats directed at Europe.

Trump's remarks had a direct impact on market sentiment in Europe, leading to key indices finishing the week in negative territory, effectively breaking a streak of consecutive gains.

His threats of imposing tariffs notably undermined investor confidence, particularly within sensitive sectors such as the automotive industry.

In Asia, the situation was similarly bleak, as Japanese stocks recorded their first weekly loss in nearly a month amid rising uncertainty regarding U.S. political developments and their potential effects on global trade.

In commodity markets, while gold prices remained stable as a safe-haven asset, oil prices concluded the week with losses, reflecting a climate of tension and uncertainty that continues to overshadow the global economic landscape despite gold seeing an increase in demand as investors sought refuge.

Collective Declines on Wall Street

U.S. indices posted a negative tally for the previous week amid increased concerns over the economy's health, coupled with uncertainties surrounding trade tariffs and renewed threats against Europe and the tech giant Apple.

Moody's Investors Service downgraded the U.S. credit rating from 'Aaa' to 'Aa1', citing rising debt levels and interest costs that are 'much higher than those of similarly rated countries'.

The S&P 500 Index suffered weekly losses of 2.6%, closing at 3,802.82 points.

Similarly, the Nasdaq Composite Index fell by 2.48%, wrapping up the week at 18,737.21 points, while the Dow Jones Industrial Average dropped by 2.47%, finishing at 41,603.07 points.

Among the hardest-hit stocks was Apple, which posted a weekly loss of 7.57% following Trump's remarks on social media regarding tariffs on iPhones sold in the U.S., implying a potential 25% tariff if the products are not manufactured domestically.

Consequently, Apple’s market capitalization fell below the $3 trillion mark to $2.916 trillion, while remaining the third-largest company behind Microsoft and Nvidia.

Other major tech stocks also saw weekly declines, with Nvidia down 3.04%, Amazon declining 2.24%, Tesla slipping 3.04%, and Meta (formerly Facebook) decreasing by 2.07%.

Conversely, shares of U.S. Steel gained roughly 20% following Trump's approval of a partnership with Japan's Nippon Steel.

European Index Struggles

In Europe, markets faced headwinds as Trump's statements coincided with the end of the trading week, exerting significant pressure on major indices, which closed in negative territory.

Trump’s threats to impose tariffs of up to 50% on European Union nations starting in June influenced investor sentiment broadly.

Treasury Secretary Scott P. Mnuchin remarked that Trump viewed the EU's trade proposals as insufficiently favorable, indicating that Trump’s threats might spur Europe in trade discussions.

As a result, the Stoxx Europe 600 index fell to 545.13 points on Friday, decreasing by 0.93% and marking a weekly decline of 0.75%.

This marked the index's first weekly loss in six weeks and the largest single-day drop since April 9, reflecting heightened investor concerns following the U.S. President's announcements.

Specifically, the automotive sector was viewed as particularly susceptible to potential U.S. tariffs, with fears of substantial repercussions if no agreement is reached.

The French CAC index suffered a weekly loss of approximately 1.93%, closing at 7,734.40 points, while Germany's DAX index fell by 0.58%, ending the week at 23,629.58 points.

In contrast, the U.K.’s FTSE 100 bucked the trend, registering a gain of 0.38%, finishing at 8,717.97 points, boosted by a trade agreement between the U.S. and the U.K., which alleviated some market concerns in that region.

Weekly Losses in Japan

In Japan, the Nikkei Index recorded its first weekly decline in over a month, falling by 1.6% to close at 37,160.47 points, despite a marginal increase of approximately 0.5% on Friday amid lower U.S. Treasury yields and a weakened yen.

The Japanese index had previously rebounded from losses incurred since President Trump announced tariffs on April 2, rising 25% from its lowest point on April 7 to its peak on May 13.

Commodity Prices

In the commodity market, gold experienced its largest weekly gains in six weeks, driven by an uptick in investor interest as a safe haven amid economic uncertainty and renewed tariff threats from Trump, along with a weaker U.S. dollar.

After a 2% rise on Friday, gold prices recorded over 5% weekly gains for the week ending May 23, surpassing $3,360 per ounce.

Conversely, oil prices, while seeing slight gains on Friday, ended the week with approximately a 1% decline, as traders remained cautious ahead of nuclear negotiations between the U.S. and Iran, amid worries over supply disruptions if talks fail.

Brent crude futures settled at $64.78 per barrel, while West Texas Intermediate futures closed at $61.53.
