Bank of Korea's Shin says the AI boom and the Middle East war push prices up from both sides
Bank of Korea Governor Shin Hyun-song said on Oct 13 that policy stays restrictive until inflation is confidently converging on the 2% target. That makes easing a distant prospect for Korean borrowers and for investors in Korean assets.

South Korea's annual consumer inflation slowed to 2.9% in September, well above the Bank of Korea's 2% target. The bank's benchmark interest rate is 3.00% following back-to-back rate hikes in July and August.
| Figure | Value | Note | Claim |
|---|---|---|---|
| South Korea annual consumer inflation, September | 2.9% | 5 | |
| Central bank's target | 2% | 5 | |
| Bank of Korea benchmark interest rate | 3% | After back-to-back July, August hikes | 6 |
What happened
- Shin said "Inflation has really picked up, both from the cost-push and the demand-pull," citing war-driven energy costs and surging AI demand.
- South Korea's annual consumer inflation slowed to 2.9% in September but remained well above the 2% target, CNA reported.
- Shin said large cloud companies' AI infrastructure spending is estimated to exceed $1 trillion a year through 2030, and their ultra-long bonds are one factor behind rising long-term rates.
Why it matters
- What it limits constraint A cut would need all three conditions Shin named to turn: he said inflation, the exchange rate and financial stability all point toward tighter policy.
- Who's exposed exposure Shin said "some additional appreciation would also be desirable" for the won. In our view that favours dollar-based holders of won assets and trims exporters' won receipts.
- What it costs cost Borrowers carry the cost of tight policy, and Shin's justification is distributional: the bottom 20% by income spend 32% of income on food and energy, so he treats price control as help for them.
- What it sets up precedent The BOK will review its K-dot plot, which publishes its rate projections, after at least a year of use, so the format of its rate guidance could change.

Set September's print against the policy rate and the word restrictive gets thin. The rate is 3.00% after back-to-back hikes in July and August [6], inflation was 2.9% [5], and the gap is a real rate of about 0.1 percentage point on trailing prices [16], with the print itself 0.9 points above the 2% target [15].
Shin's remarks on funding bear on whether that is enough. Seoul Economic Daily read his comments on cloud-company bond issuance as a sign that AI investment could lift the neutral rate [12]. In our view that reading is right. If the neutral rate rises, 3.00% is less tight than it looks, and the BOK has to hold longer, or go higher, to apply the same pressure.
The Oct 22 review can go two ways. The BOK can follow President Lee, who gave the reasons for a near-term rise as a widening yield gap with the United States and the need to align with global tightening [7]. Or it can hold at 3.00% and let the two earlier hikes work. Shin said they "certainly had some effect that's desirable", but he declined to say whether another hike is coming [8].
Either way the rate is at least 3.00% after Oct 22, and we think a cut waits until the inflation print is much closer to 2%.
The growth side gives the BOK little to trade off. Shin said: "In (South) Korea, the AI cycle really swamps the negative effect from the Middle East. But for inflation, of course, they combine," [3]. The BOK's own expectation is that headline and core inflation stay above target for "some time" [4].
We would be wrong if the AI cycle cools. Shin's demand-pull case rests on AI spending, and the same spending is what he credits with outweighing the war's drag on growth, so a slowdown would thin both at once. We would also be wrong if the next several prints close most of the 0.9-point gap to target [15], because Shin's own test is confidence that inflation is converging, not the level of the rate [1].
What to watch
- The Oct 22 policy review: a hike, as President Lee said was near certain, or a hold at 3.00%.
- The next monthly consumer inflation print: whether it keeps falling from 2.9% toward the 2% target.
- Korean long-term yields as large cloud companies keep issuing ultra-long bonds; a further rise would support the neutral-rate reading.

Speaking to reporters, Shin said the consecutive rate hikes "certainly had some effect that's desirable", but declined to comment on whether there would be another rate rise at the central bank's policy review on Oct 22.

Shin said: "The won has appreciated significantly since the shift to a restrictive stance, but there is room for further appreciation, and some additional appreciation would also be desirable." He said a stronger won boosts households' real purchasing power and helps balance exports and domestic demand.

Shin said AI infrastructure investment by the world's large cloud companies is estimated to exceed $1 trillion a year through 2030, and that the ultra-long-term corporate bonds they issue are drawing money out of the funding pool and have become one factor behind the rise in long-term rates.

Seoul Economic Daily reported that Shin's remarks suggested AI investment could lift the neutral rate by raising demand for funding even as it improves productivity.

Shin said price stability is the most effective way to help vulnerable groups, noting that households in the bottom 20% by income spend 32% of their income on food and energy.

Shin said the Bank of Korea will review its K-dot plot, which discloses the bank's interest rate projections, after operating it for at least a year.

September inflation of 2.9% is 0.9 percentage points above the 2% target.
- [16]
A 3.00% policy rate against 2.9% annual inflation leaves a real rate of about 0.1 percentage point on trailing inflation.
