South Korea's central bank leadership argues that surging AI investment is doing more for the economy than the Iran conflict is hurting it, with the KOSPI rising roughly 4% from pre-war levels.
Here’s a sentence you probably didn’t expect to read in 2026: a central bank governor is more worried about keeping up with artificial intelligence than about a war in the Middle East.
The Bank of Korea’s new leadership has made a striking claim. The AI boom coursing through global semiconductor markets is a more powerful economic force for South Korea than the drag created by the ongoing Iran conflict and its ripple effects on energy prices.
And the numbers, at least for now, back that up. South Korea’s KOSPI index has climbed approximately 4% compared to where it stood before the Iran war began in early 2026. Taiwan’s Taiex, another benchmark heavily weighted toward chipmakers, has done even better, surging nearly 10% over the same period.
HSBC economist Frederic Neumann noted that the AI boom has helped Korea offset the energy shock stemming from the Iran situation. That’s a significant observation from a major global bank, because it suggests this isn’t just central bank optimism. Outside analysts are seeing the same dynamic play out in real economic data.
In March 2026, the BOK itself identified increased inflation risks from two converging sources: rising IT-related prices driven by strong AI demand, and climbing oil costs tied to the Iran conflict.
The timing of this economic balancing act coincides with a leadership transition at the BOK. Rhee Chang-yong, who served as governor from April 2022 through April 2026, has handed the reins to Shin Hyun Song. The new governor inherits what might be the most complex policy environment any BOK chief has faced in a generation.
The broader Asian picture offers some comfort. East Asian manufacturing economies collectively rebounded from early losses following the start of the Iran conflict, with markets recovering by late April 2026.
The risk, and it’s a meaningful one, is that this narrative relies on AI investment continuing at its current pace. Semiconductor demand is cyclical by nature. If AI spending plateaus or companies start pulling back on infrastructure buildouts, the energy shock doesn’t disappear. It just stops being offset.
Traders should also watch inflation dynamics closely. The BOK flagged both AI-driven IT price increases and energy cost pressures as inflation risks in March. If those forces compound rather than offset each other at the consumer level, household spending could take a hit that stock market indices don’t immediately reflect.
