If you’re sitting on a large cash balance waiting for something specific, a home purchase, a practice buy-in, a syndication that hasn’t called capital<\/a> yet, you have a decision to make that most people never actually make. They just leave it wherever it landed.<\/p>\n

The cost of that is real but modest. Two hundred thousand dollars in a checking account earning close to nothing, versus roughly 4 percent, is about $8,000 a year.<\/p>\n

The cost of the opposite mistake is much larger, and it’s the one worth more attention.<\/p>\n

Start with the date, not the yield<\/strong><\/h2>\n

Every dollar you’re holding either has a date attached to it or it doesn’t.<\/p>\n

If it has a date, your job is making sure it’s there on that date. If it doesn’t, it isn’t really cash, it’s investment capital<\/a>, and a savings account is the wrong place for it.<\/p>\n

The second question matters almost as much: how firm is that date? Closings slip. Capital calls arrive early. Build around the date you might actually need the money, not the one on the calendar.<\/p>\n

The four main options<\/strong><\/h2>\n

High-yield savings accounts<\/strong> are the simplest option and currently pay in the range of 4.1 to 4.2 percent at the top of the market, against a national average savings rate of 0.38 percent. The rate is variable and promotional, so banks cut quietly. The account that was competitive two years ago may not be today.<\/p>\n

Money market funds<\/strong> live inside your brokerage, which matters when you need to wire quickly. Yields are comparable to top savings accounts right now, but they track Fed moves almost immediately in both directions, while bank rates lag on the way up and fall fast on the way down. Compare funds using the 7-day SEC yield.<\/p>\n

T-bills<\/strong> run from 4 weeks to 52 weeks, with the 3-month currently yielding around 4.03 percent. Held to maturity, there’s no price risk.<\/p>\n

One practical trap:<\/strong> if you buy through TreasuryDirect, you cannot sell before maturity on that platform. You’d have to transfer the security to a brokerage first. If your date is uncertain, buy bills through your brokerage instead.<\/p>\n

Treasury ETFs<\/strong> are the convenience version. They trade like a stock, settle the next business day, and require no laddering. You give up a few basis points to the fund and accept minor share price movement.<\/p>\n

Two options most people skip<\/strong><\/h2>\n

No-penalty CDs.<\/strong> Standard CDs are wrong for an uncertain timeline, since the early withdrawal penalty is exactly the feature you don’t want. The no-penalty version removes it: you lock a rate for 11 or 13 months and can withdraw the full balance any time after the first week. The tradeoffs are a slightly lower rate, and most don’t permit partial withdrawals.<\/p>\n

Brokerage cash sweep programs.<\/strong> If your balance exceeds $250,000, multi-bank sweep programs spread deposits across a network of partner banks, pushing effective FDIC coverage well past the single-bank limit.<\/p>\n

Worth checking regardless of balance:<\/strong> what your brokerage cash is actually sitting in. At some firms the default sweep is a money market fund earning market rate. At others it’s a bank deposit sweep earning a fraction of a percent, while a money market fund paying four times that sits one click away in the same account.<\/p>\n

The state tax advantage<\/strong><\/h2>\n

Treasury interest is exempt from state and local income tax. Bank interest is not.<\/p>\n

For a California physician in the 9.3 percent marginal state bracket, a Treasury yielding 4.00 percent is equivalent to roughly 4.41 percent from a bank. The bank has to beat the Treasury by more than 40 basis points just to tie. In New York City, stacking state and city tax widens the gap further.<\/p>\n

Two details that matter:<\/p>\n

Money market funds only pass through the exemption partially.<\/strong> It applies to the portion of the fund holding direct government obligations, and California, New York, and Connecticut require the fund to clear a threshold of government holdings before any of it passes through. Funds publish that percentage annually, which means two funds with identical yields can produce different after-tax results.<\/p>\n

None of this applies in Texas, Florida, Tennessee, Nevada, and other no-income-tax states.<\/strong> There’s nothing to be exempt from.<\/p>\n

For those in the top federal bracket in a high-tax state, a state-specific municipal money market fund can sometimes win on an after-tax basis despite a lower headline yield. That’s a narrow case requiring actual calculation.<\/p>\n

Where this money should not go<\/strong><\/h2>\n

Two categories, with different failure modes.<\/p>\n

Illiquid by design.<\/strong> Syndications are 3 to 7 year holds<\/a> with no redemption right and no meaningful secondary market. The operator decides when you get your money back. Distributions can be paused, and capital calls can request more rather than return any. The same applies to private notes, hard money lending, and money lent to family or a friend’s business.<\/p>\n

None of that is a flaw in the asset. It’s simply incompatible with money that has a fixed date attached.<\/p>\n

Liquid but still wrong.<\/strong><\/p>\n
