AI Fuels Record Surpluses: Korea, Taiwan Face 2026 Rate Hikes
An escalating AI infrastructure boom is set to propel global semiconductor sales to a historic peak of US$975 billion by 2026. This tidal wave of demand for AI chips is already reshaping the economic fortunes of Asia’s manufacturing powerhouses. South Korea, for instance, just posted its largest-ever monthly current account surplus in March 2026, a staggering $37.33 billion. Taiwan, a lynchpin in advanced chipmaking, followed suit with a record $69.93 billion surplus in the fourth quarter of 2025.
This phenomenon has prompted Goldman Sachs economists, led by Andrew Tilton, to call for an “AI-driven super surplus” in both economies. Their forecast sees South Korea’s current account surplus rocketing above 10% of GDP this year, while Taiwan’s could surge past an incredible 20% of GDP. The shift is profound: AI-related exports are on track to nearly triple their contribution to South Korea’s economic output to almost 30% this year, a huge leap from less than 10% over the past decade. Taiwan’s AI-related exports are expected to follow a similar trajectory, exceeding 30% of its GDP.
Such an extraordinary export surge inevitably puts immense pressure on the central banks in Seoul and Taipei. Goldman Sachs is now pricing in two 25-basis point interest rate hikes from the Bank of Korea in the third and fourth quarters of 2026. For Taiwan’s central bank, the projection is for two 12.5-basis point increases in the second and fourth quarters. These forecasts signal impending monetary tightening, despite the Bank of Korea holding its policy rate at 2.5% in April 2026 to assess geopolitical impacts and GDP growth, and Taiwan’s Central Bank maintaining its 2.00% discount rate in March. The current wait-and-see approach cannot last forever against the influx of capital and rising inflationary risks.
According to Goldman Sachs, this AI boom marks the strongest technology cycle on record for both nations. The sheer volume of chip exports is now so massive that it’s expected to overshadow any volatility from energy import costs. Consequently, South Korea’s GDP growth should rebound to 2.5% this year from just 1% in 2025, and Taiwan’s economy could accelerate to nearly 10% from 8.7% last year. This explosive, tech-driven expansion, however, is forging a “K-shaped” growth cycle. A select group of workers will reap disproportionate benefits, leaving other sectors behind—a complex challenge for policymakers that demands targeted fiscal solutions.
For investors, the key is to watch how central banks navigate this boom, balancing export-driven growth against domestic economic stability. The long-term sustainability of AI demand and its diffusion beyond data centers remain the ultimate questions. While the outlook for Korea and Taiwan’s semiconductor-centric economies is exceptionally bright, significant headwinds persist—geopolitical tensions, shifting global trade policies, and the ever-present risk of overinvestment in AI infrastructure. The delicate task for policymakers will be managing currency appreciation while ensuring the gains from this historic boom are distributed more broadly.
