What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
Cash is guaranteed to lose purchasing power over any 10+ year period
There has never been a 10-year period since 1970 where holding cash preserved real purchasing power. The 'safety' of cash is nominal, not real.
Bonds preserve purchasing power; stocks grow it
Real bond returns of ~2-3% annualized barely outpace inflation. Real equity returns of ~7% annualized compound purchasing power exponentially. The gap widens dramatically over decades.
This is the chart for clients who say 'I just want to be safe'
Match each dollar to its job: cash for spending within the next couple of years, bonds for the middle horizon, equities for the decades — parking long-term money in cash for comfort has historically been the one 'safe' choice with a built-in real cost.
