If the Fed raises IOER, will Republican Communists scream and cry?

This is the rate of growth of excess reserves, mainly a demand deposit account for the member banks.  Note the period from 2011 through 2012 when the rate of growth bounced around zero.  I would consider this normal for a demand deposit account, perhaps a little more growth maybe, but near normal.  Note that after the QE ended, the excess reserves start to look like a normal demand deposit account, once again.

Note the frequency at which the funds change, about once a quarter, likely because the member banks and non member banks use these funds to adjust liquidity levels on a quarterly basis.

What happens if the Fed raises the interest paid on these reserves? Member banks will likely do a combination of adjustments.  They might raise the rates they pay on demand deposits for large non-member banks, and likely the debt cartel will raise the interest DC pays on two year money, and DC will be pushed farther out on the curve.

If all this works, excess reserves will be two year stable, deposits offered by member banks to large institutions will be one year stable, and the Republican Communist party will scream bloody murder.  They intend to spend money like madmen.

It is literally impossible to raise rates at all as long as a bunch of lunatic Republican Communist Party members controls Congress.
