The fourth of a series of posts on MMT, ‘The Chicago Plan Revisited’, and related issues...
There are actually two concerns most advocates of Full Reserves have:
1. Solvency – there are few solvency issues with full reserves; not surprisingly a major concern in the 1930s for Simons, Fisher, The Chicago Plan etc.
2. (Endogenous) money creation
The second is much the more important, but the two are often confusingly conflated. Partly this is because the significance of the fact that the loanable funds model is wrong and there is no money multiplier is not always fully appreciated by Full Reservers.
Banks do not make loans based on reserves or loanable funds but based on demand, perceived profitability, and the capital they hold. The government covers reserve requirements later. Raising reserve requirements can raise costs but does not stop money creation. Even the focus on sight deposits (i.e., PositiveMoney) misses the point – not only do reserve requirements not stop money creation, neither does stopping lending based on sight deposits. Banks loans pull money from the central bank, with the limit being the ratio of capital to risk-weighted assets.
So, unless Full Reservers are only worried about bank solvency, which is doubtful, they are really addressing concerns that have their root in endogenous money.Clint Ballinger
