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 lockAfter the lock

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:

Deposit90 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 lockCD
How long the rate is fixedA short promo term, such as 60, 90 or 120 daysThe whole term, often 6 months to 5 years
Withdraw early?Yes, at any timeUsually only with an early withdrawal penalty

Best forCash you may need, with a short rate guaranteeMoney 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.

Which Raisin account has a rate lock right now?

The one we review is Western Alliance Bank High Yield Savings: 4.30% APY locked for 90 days, then the standard rate, $1 to open and no account fees. Raisin offers locks on select accounts and terms change, so check the product page before you open. If you would rather skip the promo and just take a steady rate, BMW Bank High Yield Savings pays 4.15% APY (Nov 5, 2026, per Raisin) with no lock.

Does withdrawing during a lock affect the STACK bonus?

It can. Raisin says rate lock accounts qualify for the STACK welcome bonus and boost, but withdrawing during the 90 day maintenance period may reduce your qualifying balance and your bonus. Bonus tiers start at $40 for $10,000 and reach $900 for $200,000. New Raisin customers only; code STACK at sign up; first deposit started by Nov 30, 2026, 11:59pm ET; money deposited within 14 days and kept on Raisin for 90 days. See our Raisin STACK bonus guide.

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.
