Why do rates jump around so much?

I totally get the temptation to wait for that “perfect” rate, but it’s such a moving target. I’ve always wondered - how much does credit score actually factor into those daily rate jumps? Is it mostly market stuff, or does your personal credit profile make a bigger difference than people think?

Honestly, your credit score doesn’t have much to do with the daily ups and downs you see in rates. That’s almost all driven by the market - think inflation news, Fed meetings, bond yields, all that fun stuff. Your credit score matters for what specific rate you qualify for, but it’s not changing day-to-day like the market rates do. I’ve had clients with top scores get caught in a sudden spike just because of bad timing, so waiting for the “perfect” moment can be a gamble.

I get what you’re saying - “your credit score matters for what specific rate you qualify for, but it’s not changing day-to-day like the market rates do.” That lines up with what my broker always tells me. Still, I wonder, has anyone seen lenders tweak their rate tiers or credit score brackets in response to fast-moving markets? Like, do the thresholds ever shift when things get volatile, or are those usually locked in for longer stretches?

I’ve actually wondered about that too. From what I’ve seen, the main credit score brackets (like 740+, 700-739, etc.) don’t seem to move around much, even when rates are all over the place. But I have noticed some lenders get stricter with approvals or add more fees during crazy market swings. Has anyone ever seen a lender suddenly change their score cutoffs, or is it mostly just the rates and fees that shift?

I’ve actually seen a couple lenders quietly tweak their minimum score requirements during the crazier parts of the market - usually not by a ton, but enough to notice if you’re watching closely. It’s not super common, but it does happen, especially with smaller banks or credit unions. I think the bigger shift is still in rates and fees, like you said, but I wouldn’t say the score brackets are totally set in stone either. Maybe it just doesn’t get publicized as much?
