Episode notes
Nominal Vs. Real Returns Matter
- Nominal returns state your headline gain but ignore inflation and other erosive factors.
- Real returns adjust for inflation and reveal your true change in purchasing power.
Money Market Gains Masked By Inflation
- Vanguard's VUSXX returned about 14% from 1/1/2022 to 4/30/2025, averaging nearly 4% per year.
- Inflation erased that gain and left money market investors with a negative 1.42% real return.

- Over the last 97 years one-month T-bills returned about 3% per year on average.
- Average inflation over the same period was roughly the same, so cash rarely outpaces inflation long-term.
