Window Guidance

Window guidance was the Bank of Japan's practice of instructing commercial banks how much to lend, and often to which sectors, quarter by quarter. Used through much of the postwar era and formally abandoned in 1991, it steered credit first into industrial reconstruction and later into the property and stock boom that collapsed after 1990.

Why it matters

Window guidance is the clearest historical example of credit being allocated by administrative decree rather than by price. It worked spectacularly during Japan's high-growth decades and then helped inflate one of history's great asset bubbles, as lending quotas kept expanding into real estate regardless of underlying demand. Researchers such as Richard Werner have argued the quotas were a primary engine of the bubble economy.

The practice never fully died. China's central bank still uses window guidance to direct bank lending, and every modern regime of macroprudential nudges and sectoral lending programs is a softer relative.

In the gold vs bitcoin debate

Window guidance illustrates how deeply states can steer money and credit when both are creatures of the banking system. Advocates of gold and bitcoin cite such episodes as the case for assets that exist outside politically directed credit: no lending quota can conjure more metal or more coins, and no guidance meeting can decide who deserves them.
