I am a strong proponent of loading up on I Savings Bonds issued by the US Government treasury. In treasury’s own words
I Bonds are a low-risk, liquid savings product. While you own them they earn interest and protect you from inflation.
- Sold at face value; you pay $50 for a $50 bond.
- Purchased in amounts of $25 or more, to the penny.
- $10,000 maximum purchase in one calendar year.
- Issued electronically to your designated account.
