US Markets Slammed by Trump’s Tariff Shocks
Global markets slumped this week after President Trump announced sweeping tariffs, igniting a full-scale global trade war. Governments responded swiftly, launching retaliatory measures that triggered a flight to safety. The Nasdaq Composite Index plunged 10.02% in the week ending April 4, while the S&P 500 and the Dow lost 7.86% and 9.09%, respectively.
In the bond markets, 10-year US Treasury yields tumbled to 3.86% before settling at 4%, a 25 bps drop for the week.
Tariffs, Retaliations, and Downgrades Rattle Investors
Tuesday’s tariff announcement set off a chain reaction in global markets. Key US tariff measures included:
- China: 34%, bringing total US tariffs to 64%.
- Taiwan: 32%.
- South Korea: 30%.
- Japan: 24%.
Fitch Ratings responded by downgrading China from A+ to A, with a stable outlook. The rating agency also forecast GDP growth of 4.4% in 2025, down from 5.0% in 2024, citing the unexpectedly high tariffs and a likely global slowdown.
On Friday, April 4, China announced a series of countermeasures, including:
- Canceling a deal to sell TikTok to the US.
- Imposing 34% tariffs on US goods, effective April 10.
- Export controls on select rare earth items.
- Suspension of import licenses for six US companies’ products.
Despite the retaliatory measures, China has not devalued the Yuan, suggesting a willingness to negotiate. The USD/CNY gained 0.25% in the week ending April 4, closing at $7.2808. In February, we noted China’s similar refrain from devaluing the Yuan in response to earlier US tariffs, contrasting with its strategy during Trump’s first term.

Market Commentary: The Kobeissi Letter: The Kobeissi Letter commented on China’s tariffs on US goods:
“Here’s the real question: President Trump says China was charging the US 67% tariffs before his reciprocal tariffs were announced. Then, President Trump charged China a 34% tariff rate on Wednesday. Today, China tariffs all US goods by 34%, and assuming this is on top of the 67% claimed by Trump, that’s a total of 101%. What does Trump do now?”
If China has raised tariffs on the US to 101%, Trump may counter with additional reciprocal tariffs on reciprocal tariffs, risking another market shock.
Headlines on tariffs overshadowed key US economic indicators, including labor market and services data.
Hang Seng Index Falls as Trade War Escalates

The Hang Seng Index declined for the fourth consecutive week, falling 2.46% amid fears of a global recession. However, the Hong Kong and Mainland China markets were closed on Friday, April 4, for the Ching Ming Festival, tempering the week’s losses.
- The Hang Seng Technologies Index slid 3.51%, with heavy losses in the EV and tech sectors.
- BYD Electronic (00285.HK) plunged 10.71%, BYD Company Ltd. (01211.HK) slid 7.87%, NIO Inc. (09866.HK) fell 4.96%, and Li Auto (02015.HK) declined 2.11% in the shortened week.
- Tech giants Alibaba (09988.HK) and Baidu (09888.HK) posted weekly losses of 5.73% and 5.95%, respectively.
However, these names could face a tumultuous Monday if weekend trade talks or policy measures fail to boost risk sentiment.
Brian Tycangco, editor/analyst at Stansberry Research, commented:
“Chinese ADRs very much on the defensive rn (right now) without guidance from Asia since markets were closed for the Qing Ming Festival. Beijing has in the past announced market moving policies over the weekend.”
Chinese ADR moves on April 4 included BABA (-10.45%), Bidu (-9.37%), and JD.com (-9.45%).
Meanwhile, Mainland China’s equity markets saw relatively modest losses. The CSI 300 fell 1.37%, while the Shanghai Composite Index dropped 0.28%. Upbeat Manufacturing and Services PMI data and stimulus hopes helped cushion declines.
