Smart ways to spread out your savings and earn more interest from your bank. Getty Images By Eleanor Laise, Senior Editor June 27, 2018From Kiplinger's Retirement Report Savers with high cash balances face a conundrum: How can they earn competitive yields without sacrificing federal deposit insurance coverage?SEE ALSO: 6 Ways to Beat Rising Interest Rates As the Federal Reserve raises interest rates, the question takes on greater urgency. Some banks are now offering yields north of 2%, which is the Fed’s inflation target, “so for the first time in more than a decade, savers are in a position where they can have a positive after-inflation return without giving up federal deposit insurance protection,” says Greg McBride, chief financial analyst for Bankrate.com. The issue for savers with sizable cash balances — including many retirees — is that federal deposit insurance typically covers only $250,000 for each account type that you hold at a single bank. So keeping all of your cash in the highest-yielding account you can find may not be an option. There are ways to earn decent yields while maintaining full insurance coverage, including titling accounts in different ways at a single bank, opening accounts at multiple banks, and taking advantage of online services that will spread your money among several banks while optimizing your yield. For someone with a substantial cash hoard, “a difference of a quarter percentage point makes a big difference in interest income and could well justify doing a little additional legwork,” McBride says.

In 2017, the average high net worth individual stashed about 21% of assets in cash and cash equivalents, according to the Capgemini World Wealth Report. But those who aren’t hunting for the best yields may pay a hefty price. Although some online banks have offered more-generous yields as the Fed raises rates, many brick-and-mortar banks have been slow to pass on higher rates to depositors. One of the best ways to earn juicy yields at the bank — a rewards checking account — does little to help high-balance savers. These accounts are offering yields of up to 5%, but those generous rates apply only up to a certain balance — often $10,000 or $15,000. What’s more, savers who want to earn the highest yields in these accounts typically must jump through some hoops, such as completing 15 debit card transactions per month. So maintaining multiple accounts may be too much work.

MaxMyInterest, launched in 2014, allocates customers’ money among online savings accounts offered by Barclays, Ally Bank, American Express, Goldman Sachs and UFB Direct. The service, which has no minimum balance requirement, keeps the amount in each account under the Federal Deposit Insurance Corp. limit, and it allows an individual saver using all five banks to easily insure up to $1.25 million. At least once a month, or as often as the customer requests, MaxMyInterest reallocates the cash to take advantage of the highest rates. To get started, customers link a checking account to MaxMyInterest and indicate how much they’d like to keep in that account. The service optimizes the yield on the excess amount by spreading it among the online savings accounts. The average customer is earning a yield of more than 1.6%, says chief executive officer Gary Zimmerman. But the service comes at a price: Annual fees total 0.08% of the amount optimized.

Websites such as Bankrate.com and DepositAccounts.com can help you find banks offering the best rates. Boost FDIC Coverage at One Bank If you want to keep all your cash under one roof, you can boost your FDIC coverage at a single bank by maintaining multiple accounts that are titled differently. For example, a married couple could have a joint account insured up to $500,000, two individual accounts each insured up to $250,000, and two retirement accounts each covered up to $250,000, bringing their total FDIC coverage to $1.5 million. SEE ALSO: Earn Up to 11% on Your Money Another approach: Set up a “payable on death” account — one that will transfer funds to your named beneficiaries upon your death — and designate multiple beneficiaries. Generally, deposits in such accounts are insured up to $250,000 for each beneficiary. You can name up to five beneficiaries and get up to $1.25 million in coverage. Note that “each of the five beneficiaries doesn’t have to receive an equal amount of the deposit,” says Ken Tumin, editor of DepositAccounts.com. “You could have the vast majority going to one beneficiary,” and the FDIC still provides up to $1.25 million in coverage, he says. (If you have more than five beneficiaries, the rules get more complicated.) To calculate how much FDIC coverage you might get with different account types, use the FDIC’s electronic deposit insurance estimator. While keeping all your cash in one place is convenient, “it very likely means you’re not getting the best yield,” McBride says. Advertisement Some savers aim to boost their yield — and their FDIC coverage — by buying brokered certificates of deposit issued by various banks. These CDs, available through brokerage firms such as Vanguard and Fidelity, are traded on a secondary market and may respond more quickly than direct CDs to interest-rate changes — giving savers higher yields as rates rise. But they come with several caveats. FDIC coverage on secondary-market brokered CDs applies only to the par value — if you purchase these CDs at a premium, the amount above par won’t be covered. Avoid callable CDs, which allow the bank to terminate the CD early. And only buy brokered CDs when you’re certain you’re going to hold them to maturity. If you try to sell early in a rising-rate environment, “you could take a bath,” McBride says.

Yields on Treasury bills and notes have climbed substantially and “are very competitive with CD rates and Internet banks,” Tumin says — and they’re backed by the full faith and credit of the U.S. government. The six-month Treasury bill, for example, yielded 2.13% in early June, compared with 2.05% for the top-yielding six-month CD listed on Bankrate.com. You can buy Treasury bills directly from the federal government.
