Alden explains how a sustained 6% 10-year Treasury yield could raise federal interest costs and pressure mortgages, housing, and affordability.
The brief
Lyn Alden argues that rising debt, persistent deficits, and refinancing needs could push the United States toward fiscal-dominance conditions, where interest costs increasingly constrain policy.
The key threshold is not a single default point: sustained higher yields would progressively increase federal interest expense, mortgage costs, housing pressure, and consumer strain.
Alden explains why long-term yields can rise even during Fed easing, warning that yield-curve control and bond purchases could damage central-bank credibility.
The conversation broadens to cash yields, Bitcoin, stablecoins, and crypto’s fading retail enthusiasm, including Orange Juice’s plan to acquire cash-flowing businesses while holding Bitcoin.
On AI, Alden sees real bubble risks but expects the trend to continue longer than many anticipate, favoring caution around semiconductors, hyperscalers, and unprofitable companies.
