Frequently Asked Questions

Why does cash in a savings account lose value over time?

Even if savings accounts pay interest, the rate is almost always lower than the rate at which central banks print new currency. Over time, the expanding money supply dilutes the purchasing power of idle cash.

Did government bonds protect wealth over the past century?

No. US government bonds grew 77.2x since 1928, which is only a fraction of the 473.3x money supply expansion, resulting in a loss of over 80% of relative purchasing power.
