# Why are required reserves so trivially low?

We know that required reserves are the reserves that central bank requires banks to hold in reserves.

Reserves= Required Reserves +Excess reserves.

But I see that in 2017 Total Reserves (RESBALNS) = 2000 Billion whilst Required Reserves (RESBALREQ) are only 124 Billion.

If required reserves are so low how could changing it possibly effect anything? Am I not using the right indicators?
