If you’re holding a six-figure cash balance, the best jumbo money market rates today can help you earn far more interest than a standard savings account while keeping your money accessible. As of November 17, 2025, top jumbo money market accounts are paying around 4.4% APY, while the FDIC’s national average money market rate is just 0.59% APY.

This daily-refresh guide highlights standout jumbo money market accounts, shows how much more you can earn and helps you decide if a jumbo MMA is the right parking spot for $100,000 or more.

Jumbo Money Market Quick Facts

• Top jumbo MMA APY today: Up to 4.42% APY on large balances at select online banks
• Best general MMA rate today: Around 4.50% APY at Hyperion Bank, over 7x the FDIC national average of 0.59% APY
• Typical “jumbo” threshold: Often $100,000-$1,000,000+ to earn the highest APY
• FDIC/NCUA insurance: Up to $250,000 per depositor, per insured bank, per ownership category
• Cash piling into safe accounts: Money market fund assets recently hit about $7.5 trillion, a new record as investors seek safe yield

What Is a Jumbo Money Market Account?

A jumbo money market account (MMA) is a deposit account that:

• Requires a large minimum balance (often $100,000 or more)
• Pays a higher APY in exchange for that larger balance
• Typically offers check-writing, debit card or ATM access, like a hybrid between savings and checking

Most jumbo MMAs at banks and credit unions are FDIC or NCUA-insured, so they’re generally considered low-risk, principal-protected places to park big cash balances, as long as you stay within insurance limits.

How Much More Can a Jumbo Money Market Earn?

The rate gap between an average money market and a top jumbo account is wide in 2025:

• FDIC national average money market rate: 0.59% APY
• Top jumbo money market APY today: 4.42% APY at First Internet Bank on $1 million+ balances

Over one year, that difference really shows:

That’s roughly $38,000 more interest in one year on a $1 million balance when you move from an average MMA to a top jumbo account.

Are Jumbo Money Market Rates Likely To Change Soon?

Short-term rates remain elevated, but the path forward depends heavily on the Federal Reserve:

• FDIC data still pegs the national money market average at 0.59% APY, with a cap of about 1.33% for most banks.
• Top money market accounts from online banks are paying around 4.25% to 4.50% APY as of mid-November.
• Money market fund assets have surged to about $7.53 trillion, suggesting many investors are keeping cash in short-term vehicles while they wait for a clearer rate direction.

If the Fed cuts rates more aggressively, jumbo MMAs could drift lower. That’s one reason some savers split cash between:

• Jumbo money markets for flexibility
• Short-term CDs or Treasurys for more predictable yields

How To Choose the Best Jumbo Money Market Account

When you compare jumbo MMAs, use this quick checklist:

1. APY vs National Average

Aim for accounts paying well above 4% APY, not just a slight bump over the 0.59% average.

2. Balance Tiers and Minimums

• Confirm the minimum to open and the balance required for the top jumbo tier.
• Some institutions only pay their highest rate at $1,000,000+, so make sure your balance qualifies.

3. Fees and Withdrawal Rules

• Watch for monthly maintenance fees and what it takes to waive them.
• Check whether the account limits certain withdrawals (for example, more than six regulated withdrawals a month) or charges excessive transaction fees.

4. Access and Features

Decide how you’ll use the money:

• Need check-writing or a debit card? Confirm that’s included.
• Prefer branch access? A regional bank or credit union may be better than an online-only institution.

5. FDIC/NCUA Coverage Strategy

• Remember: Insurance generally covers $250,000 per depositor, per institution, per ownership category.
• If you’re over that threshold, consider:
  • Splitting funds across multiple banks
  • Using different ownership types (for example, individual vs joint) to increase coverage

Jumbo Money Market vs Other “Safe” Cash Options

For large, short-term cash balances, jumbo MMAs compete with:

• High-yield savings accounts: Many pay around 4.25% to 5% APY with lower minimums.
• Short-term CDs: One-year CDs can offer 4%+ APY, but your money is locked in unless you pay an early withdrawal penalty.
• Treasury bills: Short-term government debt you can buy directly or via a brokerage; often competitive with top cash rates and backed by the U.S. government.

If you know you’ll need your money soon, a jumbo MMA gives you rate upside plus easy access, while CDs and Treasurys can help lock in yields for a set period.

Final Take to GO: Are Today’s Best Jumbo Money Market Rates Worth It?

If you have $100,000 or more in cash, the best jumbo money market rates today give you a rare combination of high yield, safety and flexibility. Earning around 4% to 4.4% APY instead of the 0.59% national average can add thousands of dollars in annual interest without locking up your money for years.

These accounts tend to work best if you can:

• Meet the jumbo minimum balance
• Stay on top of any fee-waiver rules
• Keep your total deposits within FDIC or NCUA limits by spreading funds across institutions if needed

If you’re still deciding where to put money for retirement or near-term goals, consider pairing a jumbo money market account with short-term CDs or Treasurys for extra rate stability. Then review your options regularly so you can swap in new top-yield accounts as rates move.
