How to earn more on $40,000, and one savings choice to avoid

Why the Fed still sets the tone

A $40,000 cash balance is finally earning something again, but the gap between “safe” and “productive” is still wide. The Federal Reserve’s most recent decision kept the federal funds target range at 3.5% to 3.75%, and the Fed says it steers that benchmark mainly through the interest it pays on reserve balances and its overnight reverse repurchase facility. That matters because savings accounts, CDs, and other short-term cash products still price off that policy backdrop.

The inflation test is what makes the decision more than a rate chase. The Consumer Price Index rose 3.8% over the prior 12 months in April 2026, while the FDIC’s May 2026 national-rate table put average savings accounts at 0.38% and bank money market deposit accounts at 0.57%. On $40,000, 0.38% produces only about $152 a year before tax, which is why a plain savings account can feel reassuring yet still leave you losing purchasing power.

High-yield savings is for access, not for winning the race

A high-yield savings account makes sense when access matters more than squeezing out every last basis point. FDIC deposit insurance is automatic up to at least $250,000 per depositor, per ownership category, at each FDIC-insured bank, so a $40,000 balance fits well inside the safety net. That gives you immediate liquidity for emergencies, taxes, or a near-term purchase without taking credit risk or lockup risk.

The tradeoff is that most cash accounts still trail inflation. The FDIC’s average savings rate of 0.38% and money market deposit account average of 0.57% show that “cash in the bank” is still a yield compromise, not a return strategy. If rates fall later this year, the relative appeal of these accounts rises only because alternatives reset lower, not because the accounts themselves suddenly become strong inflation hedges.

CD ladders matter if you think rates may slip later

A CD ladder is the middle ground between yield and flexibility. You lock part of the money into fixed terms, then spread maturities so cash comes back in stages instead of all at once. In a setting where the Fed still anchors short-term pricing, that structure lets you preserve today’s yield on at least part of the balance if rates fall later, while avoiding the all-or-nothing decision of a single long CD.

The FDIC’s national-rate table also shows why savers still shop beyond the average. In that May 2026 snapshot, the national average was 1.24% for a 3-month CD and 1.35% for a 6-month CD, both far below Treasury bill benchmarks. Those averages are not the ceiling, but they do show the baseline that ordinary deposit pricing is still climbing from a very low level.

Treasury bills are the cleaner yield-versus-tax tradeoff

Treasury bills are the simplest option when you can give up access for a few months. TreasuryDirect says bills run from four weeks to 52 weeks, and Treasury’s daily rate data for June 1, 2026 show 26-week bills in the high-3% range. On a six-month hold, $40,000 at roughly 3.75% annualized would earn about $750 before tax, a far stronger result than a basic savings account.

Taxes are part of the appeal. Treasury says bill interest is subject to federal tax but exempt from state and local income taxes, which can make T-bills especially efficient if you live in a high-tax state. They are not FDIC-insured, but the FDIC itself notes that Treasury bills, notes, and bonds are backed by the full faith and credit of the U.S. government.

Money market funds sound like cash, but they are not deposits

This is where a lot of ordinary savers get tripped up. The SEC says money market funds are a type of mutual fund that invests in short-term liquid assets and pays dividends that reflect short-term interest rates, which is why they often feel close to cash. But the FDIC’s list of products that are not insured includes mutual funds, so a money market fund does not carry deposit insurance the way a savings account or a bank money market deposit account does. That is the hidden downside: the name sounds safe, but the wrapper changes the risk.

If you want true deposit protection, the account version is the one to check, not the fund version. A bank money market deposit account still sits inside the FDIC umbrella, while a money market mutual fund does not. For cash you might need on short notice, that distinction matters more than the yield label.

I bonds and EE bonds belong in the sidecar, not the whole garage

Series I savings bonds are the most compelling inflation-linked bond in this group right now. TreasuryDirect says I bonds issued from May 1, 2026 through October 31, 2026 carry a 4.26% composite rate, including a 0.90% fixed rate, while Series EE bonds issued in the same window earn 2.40%. Both are subject to federal tax but not state or local tax, which improves the after-tax math versus ordinary bank interest.

The catch is scale and patience. TreasuryDirect says you can buy up to $10,000 of each electronic series per calendar year for yourself, so I bonds and EE bonds can only absorb a slice of a $40,000 balance. EE bonds also carry the marketing hook of doubling in 20 years, which sounds attractive, but that is a very long wait for money that may need to stay flexible.

The one savings choice to avoid

The weakest move is to park the entire $40,000 in a plain savings account and call it prudence. FDIC insurance protects the principal, which is real protection against bank failure, but it does nothing against inflation when the national average savings rate is 0.38% and consumer prices are rising 3.8% over 12 months. The hidden downside is simple: safety from a bank problem is not safety from a loss of buying power.

For most savers, the better answer is not a single bucket but a deliberate split. Keep the money you truly need soon in an insured account, use CDs or T-bills for funds you can leave untouched for months, and reserve I bonds for a capped inflation-hedging sleeve. In a world where the Fed still sets the tone, the winners are the people who match each dollar to its job instead of treating every cash-like product as interchangeable.
