IMF's Vamvakidis wants Korea's chip-boom tax windfall held back for the next downturn
IMF deputy director Athanasios Vamvakidis says Korea should save its chip-boom tax windfall because rising bond yields are lifting government interest costs. The October GFSR puts about $950 billion of equity and debt behind 13 circular AI deals, a loop its analysis says could cut funding and revenue together.
The Investor · Invest desk
Debt is about 68% of the financing linked to the 13 circular AI deals. The deals total about $950 billion of equity and debt. There are 13 publicly disclosed circular financing deals since 2023.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Debt share of financing linked to the 13 deals, about | 68% | 20 | |
| Equity and debt total, about | $950 billion | 18 | |
| Circular deals since 2023 | 13 deals | 7 |
What happened
- The October Global Financial Stability Report, released on Oct. 13, lists three top risks to markets: a correction in markets driven by AI, a sharp rise in sovereign bond yields, and cyber threats.
- Vamvakidis said he was not familiar with the government's use of chip-boom revenue to redeem about 5 trillion won in treasury bonds, and that extra revenue should first be considered for saving.
- He said Korea must first distinguish whether the chip revenue increase is temporary or lasting, and that a stable stream could later be considered for use for future generations.
- The IMF attributed this year's rise in yields to higher energy prices from the war in the Middle East and to shifts in the monetary policy outlook at major central banks.
Why it matters
- constraint Large-scale fiscal support is harder to deploy once a crisis hits, the fund said, so the good years are the only window for building a buffer, and a windfall committed to recurring items leaves less to draw on later.
- decision Any spending decision has to be made with the central bank in view: Vamvakidis said that if a government expands spending while its central bank tightens to curb inflation, the two policies can work against each other.
- exposure Vamvakidis said AI share prices are not necessarily excessively overvalued, but that the economy and markets are far too dependent on AI, so a shortfall in AI investment returns could spread to markets and the real economy.
According to Seoul Economic Daily, the specific advice to Korea was given in an interview, not in the report. Vamvakidis spoke to Korean media on Oct. 8, after presenting the GFSR's tokenization chapter at a Bank of Korea annex [4], which was five days before the report came out [21]. The report's own argument is general: high debt and inflation leave countries less room to respond than before, so buffers should be built in normal times [12]. The paper says that message is read as applying to Korea as well [14].
The size of the risk is easier to judge once the circular deals are added up. The report links 13 publicly disclosed deals since 2023 to about $300 billion of equity and $650 billion of debt [7]. That is $950 billion [18], about $73 billion a deal [19], and 68% of it debt [20]. We think the debt share matters most. Interest on debt falls due whether or not the returns arrive, and the report's analysis found that a contraction in funding and a decline in revenue could occur at the same time [8].
The loop runs from large technology companies to AI firms to the sellers of semiconductors and cloud services [15]. Korean chipmakers presumably sit at that last stop, but that is our inference; the paper does not say what share of the windfall comes from such buyers.
The bond redemption is the one concrete use of the windfall in the interview, and the interview does not record a ruling on it [5]. Retiring bonds removes their coupons and the need to refinance them at higher yields [11], so we think it may already be a form of the buffer Vamvakidis describes.
The advice holds up if the loop is as fragile as the debt share suggests. It weakens in two cases, or rather it weakens in one and could be overturned in the other. If yields fall back, the interest-cost half of the argument goes and the case for saving rests on revenue durability alone. If the chip revenue proves stable, Vamvakidis himself said its use for future generations could be considered [6], and a Seoul that banks every won would be giving up spending he would have allowed.
Following the advice means Seoul is not building recurring spending on a revenue line whose durability, in his words, has to be established first, and it forgoes the growth that spending would have bought. The cost of the opposite error was put plainly by Vamvakidis: a hasty expansion of spending could create economic imbalances [16].
What to watch
- Whether Korea's finance ministry sends further chip-boom revenue to debt redemption or to new spending in its next budget decisions.
- Whether any of the 13 circular AI financing deals sees funding pulled, which would test the report's warning that funding and revenue can fall together.
- Whether sovereign yields keep rising on Middle East energy prices and central bank outlook shifts, which sets the interest-cost half of the IMF's case.
