The newly announced trade agreement between the US and China targets the most pressing barriers through several headline moves. The deal rolls out as follows:

• 90-Day Pause on New Tariffs: Both countries agreed to freeze any new tariffs for the next three months. This gives a breather to importers, exporters, and businesses closely tied to the cross-Pacific supply chain.
• Sharp Tariff Reductions: The US will cut tariffs on Chinese imports from a punishing 145% down to 30% for the duration of this pause. In return, China will lower its tariffs on US goods from 125% to 10%, substantially easing the cost for American companies shipping to China.
• Effective Timeline and Scope: These changes are in effect immediately and set to expire after 90 days unless there’s new progress. Some products, like certain technology and agricultural goods, are excluded due to national security or strategic interests.

Reasons Behind the Agreement

Both Washington and Beijing faced mounting pressure to relax trade barriers. Ongoing tariffs have weighed heavily on exports, slowed manufacturing, and triggered uncertainty in financial markets throughout 2024 and into 2025.

The main factors pushing leaders toward a deal include:

• Slumping Export Demand: Chinese exports to the US dropped sharply due to high tariff rates. US manufacturers supplying China felt similar pain.
• Market Instability: Prolonged trade friction has led to volatile stock and currency markets, spooking investors and dragging down valuations worldwide.
• Macroeconomic Slowdown: With both economies losing steam, leaders shifted toward compromise to kickstart growth and support jobs at home.
• Pressure from Allies and Businesses: Global allies and major companies lobbied for resolution, citing unpredictability and added costs from ongoing trade battles.

Tariffs Still in Place and Ongoing Challenges

Despite bold headline numbers, not all tariffs are gone. Many elevated duties remain, while some sectors—like advanced technology, chips, and agriculture—face uncertainty over possible exceptions.

Main challenges that still confront negotiators:

• Partial Relief Only: Many products continue to carry higher-than-normal tariffs. Companies are still facing extra costs and disrupted supply chains.
• Unresolved Policy Conflicts: Structural issues such as intellectual property, technology transfer, and state subsidies are not part of this immediate agreement.
• Short Window for Lasting Change: The 90-day countdown is ticking. If sides fail to bridge wider policy gaps, tariffs may snap back, putting pressure on future dealmaking.

Markets and policymakers have welcomed the announcement, but the limited scope and ticking clock keep uncertainty high. For more on the hurdles ahead, see Reuters’ coverage of ongoing US-China tariff negotiations.

Currency Movements and Safe-Haven Assets

Currencies reacted quickly to the deal. The Chinese yuan strengthened as capital flowed back to riskier assets, reflecting new trust in Beijing’s policy stability. The Hong Kong dollar stayed near its official peg, but sentiment in the foreign exchange market shifted from caution to optimism.

• Yuan: Rose against the US dollar, a sign that traders expect smoother US-China relations in the short term.
• Other Asian Currencies: South Korean won and Australian dollar edged up as well, as investors grew less risk averse.

Safe-haven assets showed the opposite move—gold and yen dipped, with global markets cheering the unexpected US-China progress. Investors felt comfortable moving funds away from defensive bets to equities, underlining a powerful swing in market mood.

In summary, the Hong Kong stock surge was matched by gains throughout Asia, a stronger yuan, and a pivot away from safe-haven trades. The fast response shows just how tied Asia’s fortunes remain to trade clarity and diplomatic progress between Washington and Beijing.
