When a commercial bank makes a loan, it does not lend out pre-existing savings; it simply credits the borrower's account, creating new deposit money with a keystroke. Money therefore comes into existence as debt at the moment of lending, which means the supply of money is driven by demand for credit rather than by a prior pool of savings.
Money is not a commodity like gold but a social relationship: a promise to pay, backed by trust and ultimately by the enforcement and taxing power of the state. Its value rests on the institutions that underwrite that promise, which is why a sound monetary system is a public good requiring public institutions.
Interest rates are the price of money and the most important price in the economy, because they determine which projects are viable and how the gains from activity are split between borrowers and creditors. Seeing high real rates as a transfer from productive activity to rentiers reframes monetary policy as a distributional choice rather than a technical one.
Because banks can create credit without limit, the key question is what that credit finances. Lending into existing assets such as property and financial securities inflates asset prices and debt without adding productive capacity, whereas lending into new productive activity generates income that can repay the loan.
Private banks rely on publicly backed infrastructure — central bank settlement, deposit insurance, lender-of-last-resort support and bailouts — to create money at a profit. Since the public bears the ultimate risk of this privilege, society has a right to govern the volume, price and direction of credit through democratic institutions rather than leaving it to bankers.
Unrestricted cross-border capital mobility lets global finance discipline governments and override domestic interest-rate and credit policy. Managing capital flows is presented as a precondition for a nation to set affordable rates and steer credit toward public goals like full employment and ecological transition.
