The author argues oil is bid and not going away, citing the confirmed shutdown of the East/West pipeline and Bloomberg speculation that China is re-entering the refined products market. The mechanism is reduced supply plus returning Asian demand tightening the crude market. No explicit timeframe or risk is given.
The author argues that US debt is being financed by rolling into shorter-term debt, which is fine for now since average maturity is on the higher end of the typical range. However, once average duration falls to 2-3 sigma on the low side, conditions become dicey and that is the trigger to short TLT. The mechanism is that shortening duration signals rising refinancing risk, pressuring long-duration Treasuries. Main risk is that the duration threshold may not be reached for a long time.
