IMF upgrades South Korea's 2026 economic growth forecast to 2.6%, ranking first globally: memory chips sell too well.

The IMF's latest forecast has revised South Korea's 2026 economic growth rate upward from 1.9% to 2.6%, the largest upward revision among the world's top 30 economies in this round, highlighting that AI semiconductor exports have cushioned the impact from the Middle East conflict.

South Korea's economy expanded at an annualized rate of 7.5% in the first quarter, far exceeding the IMF's April estimate of 1.8%. This gap reflects that memory and chip sales have been much stronger than expected, so strong that the headwind from higher imported energy costs has almost lost its presence.

In the latest World Economic Outlook, the IMF significantly raised its 2026 growth forecast for South Korea from 1.9% to 2.6%, and its 2027 forecast from 2.1% to 2.5%. This is the largest upward revision among the world's top 30 economies in this round, a full 0.7 percentage points.

The IMF noted that strong external demand for semiconductor exports is sufficient to offset the negative impact of the Middle East conflict on South Korea, placing South Korea alongside Taiwan, Thailand, and Malaysia as one of the world's top four net exporters of AI hardware.

Who is paying the bill for the Middle East conflict?

The IMF's latest upgrade essentially provides international endorsement for a judgment the Bank of Korea (BOK) already made in May.

At that time, the BOK raised its 2026 growth forecast from 2% to 2.6%, for almost the same reason: chip exports being stronger than expected, continued fiscal stimulus, and a vibrant stock market – together, these factors outweighed the drag from rising energy prices.

Why can AI chips withstand the war?

There is a logic here worth highlighting. South Korea relies almost entirely on imported energy. If the Middle East conflict pushes up oil prices, it should theoretically be directly reflected in the growth figures.

But the IMF's answer is that external demand for AI hardware is strong enough to overcome this structural weakness in energy. The 7.5% annualized growth rate in the first quarter is concrete evidence of this logic: the influx of chip orders is faster than the pace at which the war pushes up oil prices. This is also why South Korea, along with Taiwan, Thailand, and Malaysia, is ranked among the world's top four net exporters of AI hardware: these economies are using the money earned from selling chips to buy a buffer against geopolitical risks.

From another perspective, this is a narrative being rewritten by the current AI boom. In the past, when an external shock hit, small, open, export-oriented economies were usually the first to be affected. But as long as a country holds an irreplaceable position in the AI supply chain – such as the high-end memory and computing hardware needed for servers and data centers – the impact can be entirely absorbed by hardware demand, and could even reverse the trend and push growth figures higher.

Of course, this resilience comes at a cost: the more growth relies on the order cycle of a single industry, the more violently it could rebound once global AI capital expenditure cools and major tech companies slow their procurement. South Korea essentially ties the downside risk of its entire economy to the earnings cycle of a few chip giants – a glimpse of this can be seen in the recent frequency of circuit breakers in the Korean stock market.

Stronger growth, tighter interest rates

However, stronger growth figures come at the cost of tighter policy space. The IMF's upgraded outlook effectively endorses the Bank of Korea's hawkish turn. Policymakers now face a set of concurrent signals: stronger-than-expected growth, persistent inflation pressure, a continuously weakening Korean won, and rising financial stability risks – all four point to the same policy answer.

Economists generally expect the Bank of Korea to raise its benchmark interest rate to 2.75% at its rate meeting on July 16. In other words, the AI boom has made South Korea's macro figures look better, but it has also given the central bank no reason to continue easing monetary policy. The foreign exchange earned from chips is, to some extent, being quietly eaten away by the cost of interest rate hikes.

For businesses and households, this is a double-edged sword: strong exports prop up GDP on paper, but borrowing costs rise simultaneously. The weakening won further increases the real burden of imported energy, creating a situation where growth and tightening occur at the same time. This makes the next steps for policymakers far more complex than the superficial growth figures suggest.
