To add what other folks have said... Banks have a conflict of interest in regards to employees coming back into the office: They hold the mortgages on all that office space. If the work-from-home trend doesn't let up they stand to lose trillions of dollars.

The bigger the bank the more they stand to lose. This is why banks like Goldman Sachs are extremely vocal about bringing people back into the office and grasp at every little thing that can find to back their claims that, "it's better". Even if the arguments they're making are based on 100% bullshit.

Example: You'll often hear big bank executives say things like, "teams that work near each other work better" knowing full well that their global workforce doesn't actually "sit near each other". On any given internal team employees will live all over the damned world so even if every one of them came back into the office they still wouldn't be anywhere near each other.

We know this is 100% bullshit anyway because if they actually stood behind these words they'd issue mandates that huge amounts of employees be relocated to the same physical locations and that hiring could only happen locally. They're not going to do that though because they know what they're saying is bullshit.
