Keeping cash on the sidelines does not necessarily mean earning nothing in 2026. High-yield savings accounts, money market funds and short-term Treasury bills are all paying meaningful returns, but each works best for a different type of saver.
Top high-yield savings accounts currently offer as much as 4.15% APY, while short-term Treasury bills yield roughly 3.7% to 4.0% depending on maturity. Large money market funds sit mostly in the mid-3% range.
That makes the choice less about chasing the highest advertised rate and more about liquidity, taxes and how quickly the money may be needed.
HYSA vs Money Market Funds vs T-Bills
| Option | Current yield range* | Liquidity | Key advantage | Main drawback |
|---|---|---|---|---|
| High-yield savings | Up to 4.15% APY | Very high | FDIC/NCUA protection | Rate can change quickly |
| Money market fund | About 3.3%-3.6% | High | Easy brokerage access | Not FDIC insured |
| Treasury bills | About 3.7%-4.1% | High | State/local tax exemption | Best held to maturity |

High-Yield Savings Offers the Simplest Option
For emergency savings or money that may be needed without notice, a high-yield savings account remains hard to beat.
Bankrate's latest savings rates show leading accounts paying up to 4.15% APY, versus a national average of about 0.63%.
Deposits at eligible banks are generally covered by FDIC insurance within applicable limits, while credit-union deposits receive similar NCUA protection.
The trade-off is that the rate is variable. If the Federal Reserve lowers short-term interest rates, banks can reduce savings APYs quickly. The current Fed policy environment therefore matters even for investors holding cash rather than stocks or crypto.
Money Market Funds Fit Brokerage Cash
Money market funds can make more sense for cash already sitting in a brokerage account.
Fidelity's SPAXX, for example, had a 3.31% seven-day yield on Aug. 20, while Vanguard's VMFXX recently yielded about 3.57%.
These funds invest primarily in short-term government debt, repurchase agreements and other highly liquid securities. They are generally designed to maintain a $1 share price.
However, a money market fund is not the same as a bank money market account. The SEC notes that mutual-fund versions are not FDIC insured, even though losses have historically been rare.
They are particularly useful for investors who want cash ready to deploy into stocks, ETFs or other assets without constantly transferring money between a bank and brokerage.
T-Bills Can Win on Taxes
Treasury bills offer another strong option, especially for investors in states with high income taxes.
Recent auctions put 13-week bills around 3.8%, 26-week bills near 3.9%, and one-year bills around 4%. Bills are available with maturities ranging from four to 52 weeks.
Interest is subject to federal tax but exempt from state and local income taxes, which can make a slightly lower Treasury yield more attractive than a higher bank APY after taxes.
T-bills also let investors lock in a yield until maturity, unlike savings accounts whose rates can fall at any time. That can be useful while markets debate whether the Fed will eventually cut or raise rates. Recent moves in short-term yields show how quickly those expectations can change.
For most savers, the decision is straightforward: HYSA for emergency cash, money market funds for brokerage liquidity, and T-bills for money that can be locked away for several months.
A combination can work as well. An emergency fund might stay in a savings account while excess cash is placed in a rolling Treasury-bill ladder.
