A rate lock on Raisin guarantees a promotional APY on select savings accounts for a set term, such as 60, 90 or 120 days. When the term ends, the account switches to its standard variable APY, and you can withdraw at any time. For example, Western Alliance Bank’s savings account on Raisin locks 4.30% APY for 90 days, then moves to a standard rate Raisin lists at 4.00% APY (as of Oct 27, 2026). Rate lock accounts also count toward Raisin’s STACK cash bonus. Terms checked on Raisin’s website on Nov 5, 2026.
A rate lock sounds like a CD, but it works differently. Here is what is locked, what is not, and what a lock is really worth in dollars.
What does a Raisin rate lock actually lock?
| During the lock | After the lock | |
|---|---|---|
| Your APY | Fixed at the promo rate (4.30% on Western Alliance) | The standard variable APY, which can change at any time |
| Withdrawals | Allowed at any time, per Raisin | Allowed at any time |
| Early withdrawal penalty | None mentioned by Raisin | None |
| New deposits | Per the product’s terms | Per the product’s terms |
| STACK bonus | Counts toward it | Counts toward it |
From Raisin’s rate lock FAQ and its Western Alliance Bank product page, checked Nov 5, 2026. Each product’s terms can differ, so read them before you deposit.
How much is a 90 day rate lock worth?
Less than the headline suggests. The lock adds the gap between the promo rate and the standard rate, for 90 days only. On Western Alliance, that gap is 0.30 percentage points:
| Deposit | 90 days at 4.30% | 90 days at 4.00% | Extra from the lock |
|---|---|---|---|
| $10,000 | $106 | $99 | $7 |
| $25,000 | $265 | $247 | $18 |
| $50,000 | $530 | $493 | $37 |
| $100,000 | $1,060 | $986 | $74 |
Simple interest for 90 days, assuming the standard rate stays at 4.00% APY. Illustration only.
The bigger benefit is certainty: for those 90 days your rate cannot be cut. The rate you live with long term is the standard one, so compare that number, not the promo, against other accounts in our best high yield savings accounts.
Rate lock vs CD: what is the difference?
| Raisin rate lock | CD | |
|---|---|---|
| How long the rate is fixed | A short promo term, such as 60, 90 or 120 days | The whole term, often 6 months to 5 years |
| Withdraw early? | Yes, at any time | Usually only with an early withdrawal penalty |
| After the term | Becomes a variable savings rate | Matures; you withdraw or renew |
| Best for | Cash you may need, with a short rate guarantee | Money you will not touch until a set date |
If you want a rate you can count on for a year or more, a CD does that job better. Compare terms on our CD rates page or build a CD ladder.

Frequently asked questions
What is a rate lock on Raisin?
A promotional APY that Raisin’s partner bank guarantees on select savings accounts for a set term, such as 60, 90 or 120 days. After that, the account earns its standard variable APY.
Can I withdraw money during a Raisin rate lock?
Yes. Raisin says you keep full flexibility to withdraw at any time. Withdrawing during the STACK bonus maintenance period can reduce your bonus.
What happens when a Raisin rate lock ends?
The rate switches to the account’s standard variable APY. For Western Alliance Bank, Raisin lists that rate at 4.00% APY as of Oct 27, 2026.
Is a rate lock the same as a CD?
No. A CD fixes your rate for the whole term and usually charges a penalty to withdraw early. A Raisin rate lock fixes a promo rate for a short term and lets you withdraw at any time.
Do rate lock accounts qualify for the STACK bonus?
Yes, provided you meet the other STACK requirements: new Raisin customer, code STACK and a first deposit by Nov 30, 2026.
