Bump-rate certificate.

What if rates go up? One solution in a rate-sensitive market is to open an STCU bump-rate certificate, with the option to hike your rate once every 18 months.

Ladder up.

Here's another trick: Ladder your savings to catch rate hikes at their peak, and smooth over rate drops over time. Open a new certificate each week or month, reducing your exposure to dramatic market changes, while also making a portion of your savings available each time a certificate matures.
