What people mean when they say “run out” is that it won’t be able to keep up with its obligations.
Huh. Maybe I’m just built diff, but when I hear “run out”, I think “run out”, as in “none will be left”; “the bucket will be empty”; “there will be nothing left in the coffers”.
Maybe I can illustrate better. Imagine your boss goes to pay you your paycheck and gives you and your coworkers 75% of what you’re supposed to be paid instead of 100%. You say, “Hey, where’s my other 25%” and they respond, “I don’t have any more, we ran out of money to pay you. We had to adjust to stay sustainable. You’ll only get 75% until our finances change.” Would you say, “well, since there’s still savings maybe, and there’s gonna be a bunch of new money the next time you go to pay out, just not enough, you technically didn’t run out. That’s technically something else?” I don’t know, maybe you would. I’d call that running out, though.
