A bank offering 3.25% isn't "struggling" either. Real struggling for a bank looks like bank runs and depression.

But you are talking the "consumer perspective". Right now the median interest on consumer savings accounts is less than 1%. [1] Someone getting 3.25% from their bank isn't "struggling" compared to their luckier neighbor that found a 4.25%. They are probably closer to the top 10% or top 1% and have a larger savings deposit and/or high credit/sustainably low debt. Most Americans can just envy that, not qualify for it.

There are opportunity costs in moving your money from a stable bank that you have an existing relationship and shopping it around to get that perfect 4.25% highest margin that you can find. Transfers are usually free for consumers, but a bank may give you a lower APR on your credit cards and a cheaper checking account if you keep your accounts all in the same place with that bank. Trying to move all of that at once for a similar deal at the 4.25% bank can risk hard credit checks and account closure notices that consequently drop your credit rating, including possibly enough to make the bank at 4.25% question your stability and change their mind on the deal.

I think consumers actually today have a better idea of the risks of these kinds of "small improvement" things than large companies. Wall Street is a much worse "Credit Rating Bureau" than the three (truly terrible) consumer Bureaus. Businesses have grown so large they no longer understand Opportunity Cost at any real level. If you shut down the things that bring in $5 billion revenue, you no longer have $5 billion revenue, you have a gamble that some other industry can ramp up to that quickly. $5 billion has never been "quick money". (Inflation would have to get a whole lot worse for that to happen and that point the company has too many other problems.)
