Frequently Asked Questions

Is Fidelity Cash Management Account a good savings option?

Fidelity Cash Management is excellent if you prioritize convenience, integration with Fidelity investments, and exceptional features like $5 million FDIC coverage and unlimited ATM reimbursements. However, at 2.21% APY, it earns roughly half what dedicated high-yield savings accounts offer (4-5% APY). For pure savings maximization, dedicated high-yield accounts are better.

Can I have both Fidelity and a high-yield savings account?

Absolutely. Many savers use both strategically: Fidelity Cash Management for everyday transactions, emergency access, and investment integration, plus a dedicated high-yield savings account (Newtek, Varo, Axos) for maximizing returns on longer-term emergency funds and goal savings.

Is Fidelity Cash Management FDIC insured?

Yes, but uniquely. Since it’s a brokerage account (not a bank account), Fidelity partners with multiple banks to provide up to $5 million in FDIC coverage—20 times the standard $250,000 limit. Your cash is deposited across partner banks to maximize insurance coverage.

Should I use Fidelity SPAXX or Cash Management for savings?

It depends on your priorities:

• SPAXX (money market): Higher yield (3.41%) but not FDIC-insured, requires Fidelity brokerage account, better for investment account cash
• Cash Management: Lower yield (2.21%) but FDIC-insured up to $5M, includes debit card/checks/ATM access, better for transaction needs

For pure savings, neither beats dedicated high-yield savings at 4-5% APY.

How safe are high-yield savings accounts compared to Fidelity?

Both are extremely safe with FDIC insurance. High-yield savings accounts offer standard $250,000 FDIC coverage per depositor, while Fidelity provides $5 million through partner banks. Unless you have over $250,000, both offer complete protection. Online banks are as safe as traditional banks—they simply pass overhead savings to customers through higher APYs.

Can high-yield savings rates go down?

Yes. Savings APYs are variable and typically follow Federal Reserve rate changes. When the Fed cut rates in late 2026, many accounts dropped from 4.5% to 4-4.35%. However, these rates still far exceed the national average of 0.39% and Fidelity’s 2.21%. Rate changes affect all variable-rate accounts including Fidelity’s.

How do I transfer money between Fidelity and high-yield savings?

Link your accounts via ACH transfer:

1. Add external account in your high-yield savings app
2. Verify account with micro-deposits
3. Transfer funds (typically takes 1-3 business days)

Most users maintain smaller balances in Fidelity Cash Management for immediate access and larger balances in high-yield savings for maximum returns.

What’s the tax difference between Fidelity SPAXX and savings accounts?

Both are taxed as ordinary income at your marginal tax rate. However:

• SPAXX: Government money market, may be exempt from state tax in some states
• Savings accounts: Interest fully taxable at federal and state levels

Consult a tax professional for your specific situation.

Should I close my Fidelity account to open high-yield savings?

No need to close anything. Many people maintain both:

• Keep Fidelity for investment integration, transactions, travel ATM access
• Add high-yield savings for emergency fund and goal savings

This hybrid approach balances convenience with maximized returns.
