South Korea's Q3 GDP Accelerates Driven by AI Chips, But Household Consumption Concerns Linger

What happened

South Korea's economy grew by 1.0% in the third quarter compared to the previous quarter, surpassing the 0.7% forecast and accelerating from 0.6% in the second quarter. On a year-on-year basis, GDP grew 3.4%, also above the 3.0% expected. This robust performance was primarily driven by the global artificial intelligence (AI) chip boom, which boosted exports by 2.3% and facilities investment by 4.1%, notably in semiconductor manufacturing equipment. The country's exports have already exceeded $800 billion in the first nine months of the year, putting South Korea on track to become only the fourth country to surpass $1 trillion in annual exports. However, private consumption saw a 0.2% decline, the first in nearly four years, impacted by a stock market slump and strikes in the automotive sector. The Bank of Korea estimates that semiconductors account for about half of the economic growth.

Why it matters

South Korea's strong GDP growth, fueled by demand for AI chips, highlights the increasing reliance of the country's economy on this technological cycle. While this supports exporters and semiconductor companies as global AI demand holds up, it also exposes the market to risks should there be any instability in this sector. The economic resilience, despite weak domestic consumption, reinforces the Bank of Korea's hawkish stance, which implemented rate hikes in July and September and shows no signs of softening. This suggests that interest rates may remain elevated, impacting consumption-sensitive sectors and credit.

Market impact

Interest rates and bonds: The stronger-than-expected growth and the Bank of Korea's hawkish stance tend to keep pressure on short-end bond yields in South Korea, as the central bank has less reason to ease its monetary policy. This could lead to higher borrowing costs for businesses and consumers.

Dollar and FX: Economic strength and expectations of higher interest rates tend to support the South Korean won (KRW) against the dollar and other currencies, making it more attractive to yield-seeking investors.

Equities: The KOSPI, South Korea's main stock index, reacted with a strong rally to the news, even triggering a 'sidecar' (a temporary halt on program trading) due to volatility. Companies linked to the semiconductor and AI technology sectors tend to benefit, while domestic consumption-sensitive sectors may continue to underperform due to weak household spending.

Brazil: Indirectly, South Korea's performance, as a major global technology player, can influence global investor sentiment towards emerging markets. A scenario of robust global growth, driven by technology, could favor capital flows into emerging markets, including Brazil, although the direct impact is limited.

What to watch

Investors should monitor upcoming data on private consumption in South Korea to assess the sustainability of the economic recovery. Furthermore, statements from the Bank of Korea and future interest rate decisions will be crucial to understanding the monetary policy trajectory. The evolution of global demand for AI chips will also be a determining factor for the country's exports and investment.

Scenarios

Base Case: South Korea's economic growth continues to be driven by AI chip exports, with the Bank of Korea maintaining a restrictive stance to control inflation, despite weak domestic consumption. The won strengthens and short-term bond yields remain elevated. Risk Scenario: An unexpected slowdown in global AI chip demand or a more severe deterioration in domestic consumption could curb growth, leading the Bank of Korea to consider a pause or even a rate cut, negatively impacting the won and bond yields.
