Bank of Korea Finds Semiconductor Bonuses Driving Local Consumption, but Spending Is Skewed Toward Tesla and Department Stores

Performance bonuses from South Korea’s semiconductor boom are already showing up in local spending, but the Bank of Korea says the benefits have not yet spread evenly through the economy.

The central bank examined consumption in Icheon and Hwaseong in Gyeonggi province, along with Cheongju in North Chungcheong province. These areas sit near major Samsung Electronics and SK hynix facilities and were classified as highly exposed to the semiconductor industry. Monthly consumption there was estimated to be as much as 4% higher than in areas with less exposure.

The findings are meaningful because they show that the transmission channel from corporate earnings to wages to consumption has actually begun to operate ahead of large-scale bonus payments that will become widespread from 2027.

The increase amounted to roughly 1.1 trillion won from last year through June. If the trend continues, the total rise could reach about 1.7 trillion won by the end of this year.

Icheon is closer to the Seoul metropolitan area and commuting from the metropolitan area is possible, so we estimate that related home purchases were larger.

The effect is expected to become more pronounced next year. Samsung Electronics and SK hynix are projected to pay a combined 21.9 trillion won in cashable performance bonuses, nearly five times this year’s 4.4 trillion won. The Bank of Korea said the findings show that the chain from corporate earnings to wages and then consumption has begun to operate ahead of larger bonus payments expected from 2027.

But much of the new spending has gone toward high-priced discretionary goods rather than everyday consumption. In the first half of the year, Tesla deliveries in the semiconductor-benefit areas rose 105.6% from a year earlier, compared with 77.2% nationwide. The bank said such spending generates a weaker income effect. In Icheon, a larger share of additional income also flowed into housing than in Cheongju, limiting the consumption impact. Lee Jae-ho, a Bank of Korea official, said the effect could grow if income moves into consumption rather than assets and later spreads to services and other goods.

The spillover effect can expand when increased income leads to consumption rather than the asset market.
