Demand for AI chips continues to explode, with South Korea's export data once again surpassing market expectations.

Data released by South Korea's customs agency on June 22 shows that for the first 20 days of June, exports grew by 49.7% year-on-year on a working-day adjusted basis, continuing the strong momentum from a 52.6% increase in the same period of May.

Without the working-day adjustment, exports in raw terms surged 60.4%, while imports increased by 23.2%, resulting in a trade surplus of $17.5 billion for the month.

The driving force behind these figures remains semiconductors.

Chip exports skyrocketed by 188.4% year-on-year, while exports of computer-related products soared by 293.3%. The underlying logic is straightforward: global tech giants are investing heavily in building AI data centers, and South Korea is the world's most crucial supplier of memory chips. This AI arms race is directly boosting the country's export revenues.

South Korean exports have now recorded year-on-year growth for 12 consecutive months, with semiconductors being the primary driver in nearly every statistical period.

The Challenge of Chip Prosperity

While the export data is impressive, the Bank of Korea is facing growing concerns.

Bank of Korea Governor Shin Hyun Song stated at a press conference last week that the chip boom is complicating the inflation outlook. His reasoning is that major tech firms like Samsung and SK Hynix are paying record-breaking annual bonuses. Once this money flows into the consumer market, it could trigger broader wage increases and an expansion in household consumption spending.

He also noted that "the benefits of the chip expansion are increasingly permeating the overall economy through stronger corporate earnings, consumption, and investment."

The problem is that while this permeation brings growth, it also brings inflationary pressure. In May, South Korea's Consumer Price Index rose 3.1% year-on-year, marking the fastest pace in over two years and further cementing the central bank's hawkish stance.

A combination of rising oil prices, a weaker won, and resilient economic activity has led the Bank of Korea to adopt a noticeably tighter policy bias in recent months.

Chip exports are propping up South Korea's economic growth, boosting tax revenues, and supporting asset prices. However, as the prosperity begins to spread to wages and prices, the room for monetary policy maneuvering narrows.
