High-Yield Savings vs T-Bills: Where to Park Cash Now

For the first time in years, your emergency fund can earn a meaningful return. The question is where to keep it.

Use a high-yield savings account for money you might need this month; use T-bills for cash you can lock up a little longer.

Quick comparison

The yields are close; the differences are practical.

• HYSA: instant access, simple, FDIC-insured
• T-bills: slightly higher yield, state-tax-free, fixed term
• Both beat a checking account by a wide margin

A simple split

Keep one month of expenses liquid in a HYSA, then ladder the rest into short T-bills.

The Bottom Line

Don't let cash sit idle. Either option turns your safety net into a small income stream.
