What is Fidelity Cash Management's minimum balance?

Fidelity Cash Management Account has no minimum balance requirement. There is no monthly fee, no minimum deposit to open, and no balance requirement to access any feature — including unlimited ATM fee reimbursement. FDIC coverage of up to $5 million is available regardless of balance.

Does Fidelity require a minimum balance to earn interest?

The Fidelity Cash Management Account itself earns very little interest (near 0%). Most Fidelity CMA users keep their cash in the linked government money market fund (SPAXX or FDLXX) rather than the cash balance. The money market fund earns approximately 4–5% with no minimum investment.

Does Fidelity offer up to $5 million FDIC coverage?

Yes. Fidelity CMA balances are swept into a network of 20+ FDIC-insured program banks, each providing up to $250,000 in FDIC coverage. This gives an effective maximum FDIC coverage of approximately $5 million per account. This applies regardless of balance — even a $1,000 balance is fully FDIC insured.

Fidelity’s $5 Million FDIC Coverage Explained

This is Fidelity’s defining advantage over every competitor:

Standard FDIC coverage: $250,000 per depositor per bank. If you hold $500,000 at a bank, only $250,000 is insured.

Fidelity’s approach: CMA cash balances are automatically swept across a network of 20+ FDIC member banks (program banks). Each bank covers $250,000, giving effective coverage of:

$$20 \text{ banks} \times $250{,}000 = $5{,}000{,}000$$

Balance	Schwab FDIC	Fidelity FDIC
$250,000	✅ Fully covered	✅ Fully covered
$500,000	⚠️ $250K covered	✅ Fully covered
$1,000,000	⚠️ $250K covered	✅ Fully covered
$5,000,000	⚠️ $250K covered	✅ Fully covered

This matters most for: business owners, realtors receiving large deposits, retirees with substantial liquid assets, or anyone temporarily holding large cash balances.

Maximizing Returns: The Money Market Sweep

The CMA earns near-zero interest in its base cash position. Fidelity allows (and defaults to) sweeping cash into a government money market fund:

Fund	Ticker	Yield (approx 2026)	Min
Fidelity Government Money Market	SPAXX	~4.50%	$1
Fidelity Treasury Money Market	FZFXX	~4.45%	$1
Fidelity Treasury Only MMF	FDLXX	~4.40%	$1

Money in these funds is NOT FDIC insured (it’s in government securities), but is considered very low-risk. To ensure full FDIC coverage on your CMA balance, contact Fidelity to select the FDIC-insured bank sweep option instead.
