Trade tension alleviation, also known as trade war reduction, can have both positive and negative effects on the global economy. Here are some important points:

1. Economic Growth: Reducing trade barriers can lead to increased trade and investment between countries, boosting economic growth.

2. Rising Stock Markets: Entering new trade agreements or improving trade relations can lead to optimism in financial markets, potentially increasing stock prices.

3. Price Stability: Lowering tariffs may help reduce the prices of goods and services, benefiting consumers.

4. Impact on Jobs: Trade liberalization can create new job opportunities in some sectors, while potentially negatively affecting others.
