South Korea Is a Dying Canary for Kevin Warsh's Fed

Federal Reserve Chair Kevin Warsh is keeping a close eye on South Korea's economic situation as he navigates American monetary policy. The Bank of Korea (BOK) recently raised its policy rate from 2.75 percent to 3.00 percent, marking its second consecutive increase. This move comes as the country grapples with a semiconductor-led expansion fueled by AI hype.

While the transmission mechanism in both countries may seem similar—technology driving a rush for capital, materials, and skilled labor—the timing is particularly significant for Warsh. He is scheduled to deliver a keynote address at Jackson Hole on Friday, his first appearance at the symposium since taking office on May 22. The U.S. inflation rate remains well above the Fed's target, and Warsh's decision to hike or not hike rates will be closely scrutinized.

The South Korean economy is demonstrating that productivity gains and investment spending do not necessarily arrive simultaneously. While the AI boom is creating a price-inflating rush for resources, the productivity dividend is still incomplete. This presents a valuable lesson for American policymakers, as the country's AI expansion is manifesting through different industrial structures, such as data centers and equipment.

Nvidia's recent revenue growth of $96.2 billion highlights the acceleration of demand, with the company forecasting a 70 percent increase next year. Warsh has previously acknowledged that rapid business-investment growth in the AI sector could lead to price increases, although he remains optimistic that supply can respond and prevent persistent inflation.

As Warsh prepares to address the Fed's decision-making process at Jackson Hole, the timing of the AI boom's price effect will undoubtedly be a point of discussion.
