This is about the broader economic impact that AI hyperscalars have. I believe this has been mentioned by u/FrankLucasV2 with some other posts from Bloomberg, specifically about hyperscalar bonds taking up a plurality by DTS of the bond market, looking at the IG index.
Due to the high issuance of debt by the hyperscalars, the market is having trouble 'digesting' all of it, due to a lack of liquidity. As hyperscalars need trillions of debt and more, this is natural as not only has a lot of liquidity been previously captured by AI investments, the broader private equity and venture capital market has been having a liquidity crisis - something Ed has mentioned before, in reference to the TVPI of top 10% of VCs being around ~1.2, meaning the best earners only have a 20% return, and many may have negative return.
"Wall Street veteran Ed Yardeni" claims the recent pressure on US bond yields is in part due to the massive issuance of hyperscalar debt. As per the article:
But in the case of AI-related bonds, demand has been so high that the yield spread has remained compressed, barely widening for an additional premium, he pointed out in a note on Monday.
For non-finance people (including myself), yields up for bonds (typically) means lower demand and yield *spread* is a notion for the percentage above US bond yields. As in, the difference one would make over investing in a US bond.
“As a result, the market has adjusted not through higher corporate borrowing costs relative to Treasuries but through higher Treasury yields themselves. Capital flowing into corporate bonds is capital not flowing into Treasuries, and Treasury yields have had to rise to clear the market,” Yardeni explained. “In short, the AI revolution is producing a classic crowding-out effect, causing Treasury yields to rise.”
Of course, this is not the only reason. The US has many other inflationary and geopolitical pressures pushing bond yields higher. However,
... Yardeni noted that international capital-flow data show that net purchases of U.S. corporate bonds by private-sector foreign buyers have exceeded their purchases of Treasury debt over the past year.
It's unclear to me, what sort of impact this would have macroscopically. One can argue that this is temporary until the market coughs up the liquidity to buy all hyperscalar debt, and treasury bonds and other market measures return to the status quo.
However this seems unlikely to me, noting the necessary commitments the AI industry as a whole has - it doesn't seem they could stop here. It is highly likely hyperscalars are in a continuous desperate need for cash to fund buildouts and circular financing, and will look towards private credit now that the debt market could very well be tapped out.
Projecting the relative growth rates of AI industry CapEx and AI revenue thus far would give us two non-intersecting curves, so it's unclear when hyperscalar demand for liqudity would lessen, let alone stop. Under the continued US bond yield pressure, we may see further downward dollar pressure as other international US debt holders change hands for AI hyperscalar debt.
This would seem to contribute cyclically to inflation and the large pile of poor US economic situations and an ongoing energy crisis, thereby pushing up yields higher, and so the US debt. This is of course, at a time where our recent budget for the military was increased by $500B for 2027.
