The 1950s in Australia was a decade of major change in both central banking and the financial system. The changes fed upon one another: financial innovation responded to monetary policy; the authorities adapted their strategy in response. The private banks resisted the harnessing of their balance sheets to policy, and a protracted process of conflict and compromise unfolded. Meanwhile, the growth of non‐bank financial institutions undermined bank‐centred policy. Official controls on bank interest rates opened a space for the new intermediaries. The central bank's attempt to restrain their growth contributed to a credit squeeze at the turn of the 1960s.
