At 67, He Plans to Shift $400,000 From a Bank to a Brokerage for Higher Returns. The Coverage There Isn’t FDIC Insurance and Protects Against a Different Risk

Moving $400,000 from a bank to a brokerage in search of better returns may sound simple, but the protection on the brokerage side covers a very different risk than many retirees assume. His cash could also wind up in more than one possible place.

He is 67 and has $400,000 sitting in a bank account, but the low yield has become frustrating. A brokerage offers a higher return, so he is considering the transfer. The catch is that the money will not automatically receive the same protection it had at the bank. Brokerage coverage works differently, and where the cash lands matters.

Many retirees make a similar move when rates rise. On the Early-Retirement.org forum, one longtime saver asked whether SIPC does for brokerages what the FDIC does for banks: “I feel like an idiot for asking, but does the SIPC do the same for brokerage firms as the FDIC/NCUA do for banks? All these years, I thought…” Plenty of people share that misconception.

How Much He Could Be Leaving on the Table at the Bank

The national average 12-month CD pays 1.8%. On $400,000, that comes to about $7,040 a year. A 52-week Treasury bill yielded 4.4% at the end of October, or roughly $17,760. That difference is about $10,720 a year, which explains why he wants to move the money.

Shorter bills pay a little less: 4.0% for 4 weeks and 4.1% for 13 weeks. The top of the Federal Reserve’s target range is 4%, and money market funds generally move with those short-term rates. Still, banks are not all alike. The best online banks often pay about 2.5 times the national average.

What FDIC Insurance Protects at the Bank

FDIC insurance covers deposits such as checking accounts, savings accounts, and CDs, and it pays out if a bank fails. The standard coverage limit is $250,000 per depositor, per insured bank, for each account ownership category. That category depends on how the account is titled, such as individual, joint, or certain retirement accounts.

Banks can still fail. There were six listed failures through late September 2026, with Nano Banc in Irvine, California, the most recent on September 25. If all $400,000 were kept in one individual account at one bank, about $150,000 would already be above the limit. In that setup, his money would be less protected than he may think.

What Happens When a Brokerage Fails

SIPC stands for Securities Investor Protection Corporation. At member brokerages, it provides up to $500,000 in total coverage, including a $250,000 limit for cash. But it only applies if the brokerage fails. If the firm collapses and customer securities or cash are missing, SIPC helps recover them for customers. If investments fall because the market drops, that loss remains the investor’s responsibility.

Put simply, FDIC insurance protects your deposit dollars. SIPC is meant to ensure you get back what the failed brokerage was holding for you.

Where the Cash May Actually End Up

Uninvested cash at a brokerage typically goes into one of three places:

1. A bank sweep program. The brokerage moves idle cash into one or more participating banks. Because the money is held at banks, it receives FDIC insurance rather than SIPC protection. Using more partner banks can expand coverage, but money already on deposit at one of those banks still counts toward the same limit.
2. A money market fund. This mutual fund holds very short-term debt and tries to keep a stable $1 share price. It is not FDIC-insured. It is generally very safe, but it has broken the $1 mark before. Only money market funds have let their shares fall below $1, and that has happened rarely, including in 1997 and again in 2008.
3. Treasury bills. These are short-term loans to the federal government and are backed by the U.S. government. The interest is taxable at the federal level, but it is not subject to state and local income taxes. We recently looked at a California saver whose CD creates state tax every year that Treasuries would avoid.

How the Choices Compare for $400,000 in Safe Money

For many retirees in his position, Treasury bills held at the brokerage are worth serious consideration. They offer strong yields, they are backed by the government, and the interest avoids state income tax. SIPC handles the custody risk if the brokerage fails. A short ladder, with several bills maturing at different times, can keep money available when needed.

If he prefers to stay with banks, that can work too, but the setup has to be done carefully. He would need to spread the money across banks or ownership categories so each portion stays below $250,000, and he would want to compare online banks instead of settling for the national average.

The weakest choice is leaving all of it in one account at an average rate. That option earns the least and leaves part of the balance uninsured.

The Most Important Question Before Any Transfer

Before moving the money, he should ask the brokerage: “Where exactly will my cash sit, and what protects it?” If the answer is a sweep program, he should ask how much is FDIC-insured and at which banks. If it is a money market fund, he should understand that it is an investment. If he wants Treasury bills, he will need to buy them, since cash usually will not move into bills automatically.

He should not wire the money over and assume it is earning the advertised rate with bank-style insurance. Default cash accounts may pay less and carry different protections. One phone call can clear up both issues.
