Will it reverse? We cannot know the answer to these questions with any certainty, but my guess is that the democratisation of finance which has underpinned this rise in household debt probably has not yet run its course...” – “Eventually, household debt will reach a point where it is in some form of equilibrium relative to GDP or income, but the evidence suggests that this point is higher than current levels.” • (Battellino, “Some Observations on Financial Trends”, 25 September 2007) Another interpretation: limitless lending • Who’s in control of the money supply and debt? – Economics textbooks • The Government/Central Bank – Central Bank creates “base money” – Sets “money multiplier” – Credit Money = Base Money * Credit Money – Economic data • “There is no evidence that either the monetary base … leads the cycle, although some economists still believe this monetary myth. • … the monetary base lags the cycle slightly… • The difference of M2-M1 leads the cycle by … about three quarters.” (Kydland & Prescott 1990, p. 15) The new monetary paradigm • Money supply “endogenous” – Credit money not under government control • Inherent bias towards providing as much debt as can flog • How does it work? Simple! – Consider bank loan of $L to Firm – Simultaneously creates Deposit $L and Loan $L – Charges rL% p.a. on loan – Pays rD% p.a. on deposit – And so on… • Put together flows & you can understand credit creation – Starting from the beginning • Loan by bank created both money and debt… “Money from nothing, but your cheques ain’t free” • Loan an asset of bank • Simultaneously creates liability of money in firm’s deposit account: • Sets off series of obligations: – Interest charged on loan at rL% p.a. – Interest paid on deposit at rD% p.a. where rL > rD – Third account needed to record this: Bank Deposit BD “Money from nothing, but your cheques ain’t free” • Full system is: Interest flows: bank<―>firm Wage flows: firm―>workers Interest flows: bank―>workers Consumption flows: bank & workers―>firms New Money/Debt flows: bank<―>firms Debt repayment flows: firms―>bank Reserve relending flows: bank―>firms • Table dynamic model of self-sustaining credit economy • Can now ask “What happens to bank income if…” – New money created more quickly – Loans repaid more quickly – Reserves re-lent more quickly?
