The Kauri market reopens after nine years
AI capex has stopped being an equity story and become a competitor to governments for the world's fixed-income capacity.
The Export-Import Bank of Korea sold NZ$625mn ($372mn) of five-year notes on Tuesday. It was the first Kauri bond — a security issued in New Zealand by a foreign borrower — in nine years. The reason given was not exotic: Sungho Park, a director in the state-owned bank's treasury department, told Bloomberg that issuance costs are rising because of competing sales from "AI-related hyperscalers", and that the bank was "tapping into new markets where the impact is minimal" (Bloomberg). The amount is trivial. The mechanism is not. Bond investors have a finite appetite for duration at any given yield, and that appetite is now being bid for by issuers who do not much care what they pay. Scott Bessent said as much last week: corporate issuance is "almost yield agnostic". Alphabet sold $25bn in a single go. Bloomberg counts more than $410bn borrowed this year for data centres and related AI investment. A yield-agnostic issuer sets the clearing price for everybody else. That is the crowding-out channel, and it runs directly into the story we have been tracking on the other side of the ledger: the Treasury is buying back its own long bonds, at least $4bn per operation from 9 September, precisely to hold that clearing price down. One arm of the system is trying to suppress long yields while another arm of the same system issues into them without a reserve price. A Korean agency detouring to Auckland is a symptom, not an event. But it is the first concrete case we have seen of an official borrower rerouting because of AI capex, and it will not be the last.
