At 10% rates I think the fair value of the S&P becomes something like 2000 assuming the same earnings. High yield rates would moon and tons of bankruptcies would ensue. Consider how heavily pensions and retirement accounts are concentrated in stocks. The ramifications of reaching a point like that would be devastating, so yes, I think dead is not alarmist but appropriate.
US 10 year bond rates are 3.1%. The one time in history they have gone beyond 10% it took 2 years to go from 7.32% in Sep 1977 to reach 10% in October 1979, and then peak at 15% in 1981. It's not impossible bonds will reach 10% again. But it seems unlikely, and it seems safe to think it would take 3+ years to get there. https://www.macrotrends.net/2016/10-year-treasury-bond-rate-...
The fed will have a choice: hike rates to slow demand (10%) *OR* keep rates highish and allow financing for more supply to come online (5%). Who the hell is going to finance new gas exploration at 10%?
