# Japan and South Korea have once again launched a currency defense battle

## **Export Outlook, More Weak**

In the first half of this year, Japan and South Korea were forced to intervene in the exchange rate against the backdrop of a strong dollar. In the second quarter of this year, Japan and South Korea's foreign exchange reserves decreased by 5.5% and 1.8%, respectively.

Now, their intervention in the exchange rate may intensify.

In addition to guarding the "key points" of the exchange rate, a more important reason is that the export outlook has changed.

Both Japan and South Korea are export-oriented countries, especially South Korea.

As of 2023, the share of goods and services exports in South Korea and Japan's GDP is 44% and 21.8%, respectively, making exports crucial to their overall economic volume.

In terms of export products, South Korea and Japan have significant similarities—both primarily export machinery, equipment, automobiles, and parts.

In terms of export destinations, both South Korea and Japan primarily export to the Asia-Pacific region and the United States, with the U.S. accounting for 15.9% and 18.8% of their respective export shares.

Historically, the export prosperity of both countries has been closely related to U.S. business confidence and consumer confidence in durable goods.

 In addition, based on the important position of exports in the economies of Japan and South Korea, the domestic industrial production and equipment investment cycles of both countries also align with the export cycle. When exports decline, the impact on the entire economy is naturally amplified.

Currently, Japan and South Korea are stabilizing their exchange rates in advance for two main reasons.

On one hand, the overall demand for industrial bulk commodities globally is weaker than in the first half of the year, leading to a decline in the overall prices of exported goods from Japan and South Korea, and weakening the ability to generate foreign exchange from unit exports;

On the other hand, the arrival of Trump may bring more uncertainty to the tariff outlook for both countries.

To balance the demand for buying and selling dollars in the foreign exchange market, the authorities in Japan and South Korea have to stabilize the exchange rate in advance.
