South Korea is increasingly likely to achieve a per capita national income of $40,000 this year, driven by strong semiconductor exports and improved trade conditions. However, the dollar-denominated income is subject to fluctuations in the exchange rate, and rising prices and household debt may hinder the impact of increased income on consumption and living standards.
On September 10, Deputy Prime Minister and Minister of Economy and Finance Koo Yun-cheol stated at a government meeting in Seoul that the possibility of reaching a per capita gross national income (GNI) of $40,000 has grown. He noted, "The recovery of our economy is becoming more evident," adding that the current account GDP increased by 26.4% in the second quarter compared to the same period last year, marking the highest growth rate in 47 years.
Koo pointed to an increase of 184,000 jobs in August compared to the previous year and improvements in income across all sectors as evidence of the recovery. He emphasized that the government will not rest on these economic indicators but will design policies to ensure that citizens can feel the growth and strengthen the foundation for growth through structural innovation.
The driving force behind the increase in national income is the rise in export prices, particularly in semiconductors. According to the Bank of Korea's monetary credit policy report released on the same day, the nominal growth rate exceeded 20% in the first half of the year. The bank analyzed that the recent surge in nominal growth rates was driven by improved trade conditions due to rising export prices.
When export prices rise compared to import prices, it allows for the purchase of more imports with the same export volume, thereby improving overall purchasing power. The Bank of Korea expects this change to first increase corporate profits and, with a lag, spread to investment, tax revenue, and household income.
The key variable determining whether the $40,000 target is met is the exchange rate. The dollar-denominated per capita GNI is calculated by converting the national income in won to dollars and dividing by the population. Therefore, even if won-denominated income increases, a rise in the won-dollar exchange rate can reduce the increase in dollar-denominated income. The average exchange rate for the year is more important than the exchange rate at a specific point in time.
Moreover, the growth rate of current account GDP does not necessarily equate to the growth rate of GNI. GNI reflects not only income generated from domestic production activities but also the difference between wages, interest, and dividends received from abroad and income paid to foreign entities. To assess the annual achievement, it is necessary to consider second-half export performance, net income from abroad, and exchange rate trends. The Bank of Korea has also warned of the potential for increased exchange rate volatility due to changes in the U.S. Federal Reserve's monetary policy.
Inflation affects how citizens perceive the increase in national income. Even if nominal income rises, if the prices of goods and services necessary for living also increase, the actual improvement in purchasing power may be limited. The Bank of Korea projects that the inflation rate will exceed the target level of 2% for a considerable period due to accumulated cost increases and demand-side pressures.
Interest rate hikes to combat inflation pose a burden on heavily indebted households and businesses. The Bank of Korea raised the base rate twice in July and August, increasing it from 2.50% to 3.00%. It plans to determine the timing and pace of further increases while monitoring inflation, economic conditions, and financial stability. This is crucial as financial burdens may increase in vulnerable sectors before the benefits of income growth are fully realized.
Even if nominal GDP increases and the household debt ratio decreases relative to GDP, this does not eliminate debt risks. The Bank of Korea notes that South Korea's household debt ratio remains high compared to major advanced countries, and improved income conditions could increase demand for housing purchases. If increased purchasing power shifts towards real estate rather than consumption and leads to more borrowing, financial imbalances could worsen.
Another challenge is whether the benefits of the semiconductor boom will spread throughout the economy. According to the Bank of Korea, wage growth in the first half of the year has slowed somewhat. While household income conditions are expected to improve, if the positive effects of the strong IT sector remain confined to related companies and workers, the overall recovery in consumption may be limited.
In terms of sustained growth, global investment trends in artificial intelligence (AI) are a variable. The Bank of Korea anticipates that AI investment will increase significantly over time but also identifies concerns about profitability and increased reliance on external funding as risk factors. If financial conditions worsen or uncertainties about actual profit generation grow, investment could slow more quickly than expected, impacting domestic semiconductor production and exports.
Coordinating the government's proposed structural innovations with the Bank of Korea's responses to inflation and financial stability has become increasingly important. The Bank of Korea believes that the surge in nominal growth rates will lead to increases in investment, wages, and tax revenue, but it also cautions about the potential for financial imbalances and widening gaps between households and businesses. There is a need for effective policy combinations that can maintain macroeconomic stability while enhancing growth potential.
