Charles Hugh Smith – As you (hopefully) know, we live in a fractional reserve banking system: if the bank is required to have $1 in cash reserves for every $10 in loans, it means the bank creates $10 of new money when it issues a $10 loan. When the $10 loan is paid off, that money vanishes from the system.

The problem with fractional reserve lending is the leverage. A 10-to-1 reserve ratio means that if the bank issues a $10 loan, the borrower defaults and the borrower’s collateral (home, auto, etc.) only fetches $8 on the open market, the bank lost $2, which is more than the bank’s cash reserves ($1).

At that point, the bank is insolvent, i,e, its losses exceed its assets.

In credit bubbles, the reserve requirements may reach absurd levels of leverage. At a reserve ratio of 100-to-1, a $2 loss of value in a $100 loan will push the bank into insolvency, as it only held $1 in cash as reserves against the $100 loan.

Reserve requirements and leverage are one set of constraints on new loans; the other constraint is the income, creditworthiness and willingness of the borrower.If households and businesses decide not to borrow more, regardless of the interest rate, then raising or lowering the reserve requirements will have no effect.
