After US President Donald Trump took office, world stock markets saw huge losses, even double-digit figures, particularly related to his tariff decisions.

Following Trump's election victory last November, US stock indexes reached all-time highs, buoyed by expectations of corporate tax cuts and reduced regulations.

While equity markets, which were closed for Martin Luther King Day on Jan. 20, the day the US president assumed the presidency for a second time, started the next day with a rally, successive tariff announcements and fears of inflation and recession reversed the positive mood.

Tariffs announced for the country's largest trading partners, such as Mexico, Canada, China, the EU and Vietnam, and sectoral tariffs on products such as steel, aluminum and automobiles, caused concerns, not only in the US but in global stock markets.

After the announcement of reciprocal tariffs, indexes saw the highest daily losses since 2020, when the coronavirus pandemic hit the world.

Investors cautious

Over a period of nearly 80 days, Trump has frequently threatened the world with tariffs.

The tariff rates, which became clearer in April, put China and Europe in a difficult situation. On the other hand, the two giants have started to take steps against the US.

While China imposed tariffs at a similar rate to the US, the EU announced taxes on certain product groups, putting more than $20 billion under the tax burden.

With Trump's announcement of a 90-day suspension for countries, excluding China, stock markets have calm, but concerns are reducing investors' risk appetite.

The situation cause increases in gold prices, as safe haven; it saw historical high levels during the percent period.

Major stock markets in 80 days

From Jan. 20 to April 10, stock markets were tested by high volatility, and were mostly in the red.

The Asia Dow, which tracks leading blue-chip companies across the region, fell around 9%.

Japan’s Nikkei 225 index lost 15.1% and the Hang Seng Index, a key benchmark for Hong Kong's blue-chip stocks, rose 1.1%.

China’s Shanghai Stock Exchange dropped 3%, while India’s Sensex index shed 4.7%.

Britain's FTSE100 index lost 9.6%, Germany's DAX index posted a loss of around 5% and France's CAC 40 index dropped 9.2%.

The pan-European STOXX 600 index also fell 8.6%.

The Dow plunged 13.7%, the S&P 500 slipped 16.3% and the Nasdaq fell 21%.

The VIX Index, also known as the "fear index," rose 170%.

Tesla saw biggest drop

Shares of companies called the "Magnificent Seven" continued to decline.

Among the seven, electric vehicle producer Tesla's fell 38% from Jan. 20 to April 10.

Elon Musk, as owner of Tesla, was one of Trump's biggest financial supporters, donating more than $130 million to Trump election campaign last year.

Trump's policies, such as promising to make the US the crypto capital, supported Musk's tech-based companies’ value.

After Trump's election win, Tesla's shares soared significantly.

Nvidia followed Tesla with a loss of 23.5%, and Google's owner Alphabet with 23.2%.

E-commerce giant Amazon lost 22.6%, Meta 15.6%, Apple 14% and Microsoft 11.6%.
