Now may be a particularly good time to pay attention to where your cash is earning interest. Interest rates are rising, and banks are competing aggressively for deposits, creating opportunities to earn more by moving your money between high-yield savings accounts (HYSAs).
That’s the basic idea behind rate shopping: periodically comparing the rates available on your cash and moving your money when you find a meaningfully higher APY.
Platforms such as Raisin make this strategy easier by giving you access to savings products from multiple banks through one platform.
Keep reading if you are interested in learning how cash rate shopping works.
How rate shopping works
Suppose you have $100,000 in a Raisin HYSA earning 3.50% APY. You find another participating HYSA paying 4.10%.
The difference is 0.60 percentage points.
That seemingly small difference is worth approximately:
$100,000 × 0.60% = $600 per year
You haven’t taken on additional risk. You’ve simply moved your cash to a higher-yielding savings account.
And the larger your balance, the more a small rate difference matters.
| Balance | 0.25% higher APY | 0.50% higher APY | 1.00% higher APY |
| $25,000 | $63 | $125 | $250 |
| $50,000 | $125 | $250 | $500 |
| $100,000 | $250 | $500 | $1,000 |
| $250,000 | $625 | $1,250 | $2,500 |
| $500,000 | $1,250 | $2,500 | $5,000 |
Approximate additional annual interest before taxes, assuming the higher rate lasts a full year.
Why Raisin is useful
Normally, rate shopping means opening accounts at different banks and managing multiple relationships.
Raisin’s marketplace approach can simplify the process. You can compare participating savings products and move money between them through the platform.
Raisin transfers from its savings products to its Cash Account are immediately available, while most transfers into another savings product take 1–2 business days. Note: the Cash Account itself does not earn interest.
That makes it easier to periodically check whether another available savings product offers enough additional yield to justify moving your money.
Don’t chase every 0.05%
Rate shopping doesn’t mean constantly moving your money.
If you have $100,000 and find an account paying just 0.10% more, the potential benefit is only $100 per year.
A 0.60% improvement is worth $600.
You can establish your own switching threshold—for example, don’t move your money unless the new rate is at least 0.25% or 0.50% higher.
The right threshold depends on your balance and how much effort you’re willing to put into managing your cash.
Important caveats
Rates change. Today’s highest APY may not be tomorrow’s highest APY.
Check the details. Look at minimum balances, maximum deposits, promotional rates, withdrawal restrictions and transfer timing—not just the headline APY.
Deposit insurance matters. Eligible deposits at participating FDIC-insured banks and NCUA-insured credit unions are subject to applicable insurance limits and requirements.
This isn’t risk-free arbitrage. You’re not locking in a guaranteed spread. You’re actively managing variable savings rates.
The bottom line
Rate shopping is simply being intentional about where your cash earns its interest.
If you have $100,000 earning 3.50% and can move it to an insured HYSA paying 4.10%, the opportunity is approximately $600 of additional annual interest.
You don’t need to chase every rate change.
Just make sure your cash isn’t earning substantially less than it could.
