27 August 2020: The Fed changes how it targets inflation

At the virtual Jackson Hole symposium, Fed chair Jerome Powell announced a new framework: the Fed would aim for inflation that averages 2 percent over time, meaning it would tolerate running above target after periods below it. The change signaled that rates would stay low for a long time. Within a year inflation was running far above 2 percent, and the Fed soon had to raise rates aggressively.

The lesson: Central bank promises about the future depend on conditions they cannot fully predict or control.

What it meant for investors

$1,000 in US Treasury bonds at the start of 2020 → $929 today, vs $2,092 in the S&P 500.

We start the clock at the start of 2020, the year it happened. That is a loss of $71.43, while a plain index fund over the same years made $1,092.

What US Treasury bonds teaches: Bonds bought at very low yields carry real price risk, because the starting yield is the best guide to future bond returns.
