U.S. President Donald Trump declared that the reciprocal tariff deadline will be on August 1. By reversing his previous stance, he increased market uncertainty regarding the tariff.

President Trump stated on his social media (SNS) platform Truth Social that "tariffs will begin to be imposed starting August 1, 2025," adding that "extensions will not be allowed."

However, the day before, he sent a tariff letter to Korea and 14 other countries, indicating that the implementation of the tariff could be delayed further. Although he reversed his stance within a day, the market does not seem to be particularly concerned about the tariff uncertainty, as there were no significant movements.

Seo Jeong-hoon, a researcher at Samsung Securities, analyzed that "the U.S. stock market showed a neutral movement due to concerns that the headline risk stemming from President Trump could continue for the time being," adding, "However, due to the aforementioned context, the stock market's decline has been limited."

Lee Woong-chan, a researcher at iM Securities, stated, "Despite the announcement of a tariff rate similar to that in April, the market is indifferent to it," and added, "It seems that people easily think President Trump might retract his policy again, but the tariff policy is being imposed according to the original plan in a broad sense."

He added, "Rather than withdrawing the policy, it seems to be an effort to impose tariffs while minimizing impact on the market."
