South Korea's artificial intelligence-led semiconductor boom has not generated meaningful spillover into the broader economy, even as concerns over the won and financial stability increase the likelihood of a Bank of Korea (BOK) rate hike next month, according to Nomura senior economist Park Jeong-woo.
Speaking at Nomura's Korea Equities & Economy Media Briefing in Seoul, Park said the key issue was not whether semiconductor stocks were performing well, but whether that strength was translating into wider economic activity, as reported by The Korea Herald and cited by ANI.
AI Chip Boom: Price-Led Growth, Not Volume
"No one can deny the strength in semiconductors, and the stock market has been strong on the back of that," Park said. "The key question is whether that strength is flowing into the rest of the economy."
According to Nomura, semiconductor exports have been driven largely by price effects, while shipment volume growth has not been exceptional by historical standards. As a result, the sector's contribution to gross domestic product may be less significant than headline export figures suggest.
Business investment has been supported by chipmakers' capital expenditure cycle and is likely to remain strong through the third quarter, Park said. But the effect could fade later in the year, while construction activity remains under pressure from elevated interest rates and higher building costs.
Limited Spillover into Domestic Demand and Consumption
Nomura remains unconvinced that the benefits have become broad-based. "So far, the evidence that the warmth is spreading to domestic demand is not that strong," Park said.
Consumption data presents a mixed picture. Park noted that department store card spending rose 17%, far ahead of overall card spending growth of about 2.5%, though much of the increase appeared concentrated in luxury purchases. Meanwhile, domestic automobile sales declined about 8% in May.
"The evidence that the semiconductor and stock market boom is moving into consumption is still not very strong," Park added.
| Indicator | Performance |
|---|---|
| Semiconductor exports | Strong, driven by price effects; volume growth not exceptional |
| Business investment | Supported by chip capex, strong through Q3 then may fade |
| Department store card spending | +17% year-on-year (largely luxury) |
| Overall card spending | +2.5% year-on-year |
| Domestic auto sales (May) | -8% year-on-year |
Bank of Korea Rate Hike Plans and Financial Stability
Despite inflation being primarily supply-driven rather than demand-led, Nomura expects the BOK to raise its policy rate in July and eventually take it to 3.25%. Park said the expected move would be driven less by growth and inflation concerns and more by financial stability considerations, particularly the won and the housing market.
"A 25-basis-point hike would not change the direction of the exchange rate," Park said, adding that a much larger increase would be required to significantly influence the currency, though such a move appears unlikely given the burden it would place on households and companies.
Nomura forecasts South Korea's economy to grow 2.4% this year, below the BOK's forecast of 2.6% but above the country's estimated potential growth rate of less than 2%. "Two-point-four per cent is not a weak number," Park said. "But given the higher expectations and the limited speed at which the strength is spreading into domestic demand, we think it is an appropriate growth rate for this year."
On inflation, Park said Nomura sees current price pressures as primarily supply-driven. Employment and wage indicators do not yet show the broad inflationary pressures seen during 2021-23, and inflation could peak around August or September.
Implications for Trade and Business Executives
For international trade executives and import/export managers, the Nomura analysis suggests that the AI chip boom alone is not boosting broad-based import demand in South Korea. While semiconductor exports remain strong, the limited spillover means demand for consumer goods, intermediate inputs, and capital equipment outside the chip sector may remain subdued. The expected BOK rate hike could strengthen the won, which affects pricing of exports and imports. Companies with exposure to South Korea's domestic consumption should watch mixed indicators: department store strength is skewed toward luxury, while auto sales decline signals weakness. The fading of chip investment after Q3 could further dampen import demand for machinery and materials. Currency volatility and the BOK's rate trajectory will be key factors for hedging and pricing decisions in the coming months.
