Why does the Bank of Korea think strong semiconductor exports could push inflation higher?

The bank said rising semiconductor export prices improve terms of trade and expand real purchasing power, which can stimulate domestic demand. It warned that stronger spending could broaden price increases and keep core inflation elevated.

What economic data did the BOK cite to show the impact of export strength on Korea’s economy?

The report pointed to first-quarter real GDP growth of 3.8 percent and real GDI growth of 13.2 percent. It said rising energy prices were offset by very strong semiconductor exports, allowing GDI to grow faster than GDP.

What did the Bank of Korea do about interest rates as inflation pressures built up?

The BOK raised its benchmark interest rate at two consecutive meetings to 3 percent. It described the move as unprecedented but preemptive, saying it was intended to curb mounting inflationary pressures from improved terms of trade and stronger domestic demand.

Summary

The Bank of Korea said strong semiconductor exports are spilling over into domestic demand and could keep core inflation elevated. It warned that improved terms of trade are expanding real purchasing power and may raise price pressure. The report said a demand-side shock could add up to 0.6 percentage point to core inflation after six quarters. The BOK also raised the benchmark rate to 3 percent at two consecutive meetings, calling the move unprecedented but preemptive.

Korea's monetary policy should focus on preventing core inflation from spreading broadly and remaining elevated as robust exports spill over into the broader economy and intensify demand-side inflationary pressures, a central bank report said Sunday.

"As the recent strong performance in semiconductor exports spills over into domestic demand, there is a possibility that demand-side inflationary pressures will intensify in the future," said a report published by the Bank of Korea (BOK).

The recent boom in artificial intelligence (AI) infrastructure has pushed up semiconductor prices and improved Korea's terms of trade, while the country has continued to benefit from robust semiconductor exports.

In the first quarter, Korea's real gross domestic product (GDP) grew 3.8 percent from a year earlier, while real gross domestic income (GDI), which reflects changes in the terms of trade, expanded 13.2 percent.

When oil prices rise, GDI typically grows more slowly than GDP because deteriorating terms of trade weigh on the Korean economy, which relies heavily on crude oil imports.

However, in the first quarter, rising energy prices stemming from lingering military tensions in the Middle East were offset by very strong semiconductor exports, helping GDI grow faster than GDP.

"As the terms of trade improve due to rising export prices, GDI growth is significantly outpacing that of GDP, thereby expanding real purchasing power," the report said. "This is likely to stimulate domestic demand in the future and increase upward pressure on prices."

In past cases of demand-pull inflation, including during the post-COVID-19 pandemic period, private consumption increased as improved purchasing power boosted spending, consequently fueling inflation, while companies eased cost pressures by raising retail prices.

In particular, when the core inflation rate exceeded the mid-2 percent range, prices of other items across nearly all sectors rose in tandem, fueling higher core inflation, the report noted.

It said that during periods of high demand, a demand-side shock could add up to 0.6 percentage point to core inflation after six quarters.

"When assessing future inflation trends, it is essential to closely monitor not only the pace of the economic recovery but also the speed and intensity with which income growth resulting from improved terms of trade spills over into domestic consumption," the report said.

"Monetary policy needs to ensure that the rise in core inflation does not spread widely and become entrenched."

The BOK raised the benchmark interest rate at two consecutive meetings Thursday to 3 percent, calling the move "unprecedented" but "preemptive" to curb mounting inflationary pressures as improved terms of trade boost domestic demand.
