There are three big categories of liquid investments: stocks, bonds and cash. Typically, the progression for individuals as they begin to save is: cash first, then bonds, then stocks.

There’s also an age-related progression, generally from riskier stocks to the steadier returns of government bonds. The old-fashioned formulation is that your age in years is the percentage of savings that should be in bonds, the remainder in stocks. A 30-year old, for example, would have 70% of savings in stocks, the rest in fixed income.

A strong tailwind has been aiding bond returns in the US since the early 1980s, since after the Fed raised short-term interest rates to 20%+ to choke off an inflation spiral spawned by too-loose money policy during the Seventies. The financial collapse of 2008 required another huge dose of money policy stimulus. Recently, Trump has been badgering the Federal Reserve to push short rates below zero to cover up the damage he has done to the domestic economy since being elected, in addition to the big hole he punched in the bottom of the boat this year by his pandemic denial.

No matter how we got here, however, and no matter how bad the negative long-term consequences of Trump’s bungling, the main thing to deal with, here and now, is that one-month T-bills yield 0.13%. 10-year notes yield 0.91%. That’s because during times of stress investors almost always shrink their horizons very substantially. They’re no longer interested in what may happen next year. They just want to get through today.

My sense is that we’re bouncing along the bottom for both short and long rates–and that we’re going to stay this way for a long time. If so, not only is income from Treasures of all maturities substantially below the 1.9% yield on stocks, a rise in interest rates toward a more normal 3% will result in a loss for today’s holders of any fixed income other than cash.

So for now at least, for investors it’s all stocks, all day long.

Looked at this another traditional way, the inverse of the yield on the long Treasury should be the PE on the stock market. If we take the 10-year as the benchmark, the PE on the stock market should be 111; if we take the 30-year (at 1.68%), the PE should be 59.5.

We have to go back to the gigantic bubble of 1980s Japan to see anything similar. If the comparison is valid, then bonds are already in full bubble mode; stocks are halfway there.
