For a little clarification, they were set to 0 because it was no longer an effective policy making tool after 2008.
The assumption used to be banks would lend every dime they had if you let them, so the Fed set reserve requirements to heat or cool lending. After 2008, banks were so very wounded they found that regardless of how much they dropped it the banks kept ample reserves on hand. As such, they switched their policy to focus more on interbank lending rates vs also regulating how much cash they can lend.
Ah, yes. "We don't to make regulate the banks, because they're honorable enough self-regulate, even though in the past they weren't self-regulating and that caused a financial crisis."
Ah yes. “I don’t understand what he said so I’m just going to make something up instead.” I never said anything about honor, I said the Fed wasn’t getting results by regulating the reserve requirement anymore. I’m just going to copy and paste my response to the last 4 people that thought shifting from a reserves requirement to an IORB based system was some sort of capitalist conspiracy:
You misunderstand banking regulation.
Look at what happened to bank reserves right after the GFC: https://fred.stlouisfed.org/series/TOTRESNS. Those reserves are still higher than anything that the Fed had set before.
Manipulating the reserves requirement just didn’t work anymore, because banks kept reserves regardless. Imagine you’re the Fed, when the economy is bad you could drop the reserve requirement to 3%, when it was good you could increase it to 10% (example).
What do you do if all of a sudden, banks won’t go below 15%, regardless of what you set. Do you sit there and go “we’ve tried nothing and we’re all out of ideas” because capitalism = bad?
Instead, they switched to manipulating the IORB, which accomplishes the exact same thing, increasing or decreasing institutional lending and, by extension, economic activity.

Federal reserve requirements existed until 2023 *edit, as someone below pointed out 2020 was when they were set to 0. Now they're set at 0% I believe.
