Monetary financing
The direct financing of government spending by the central bank. This happened during the hyperinflation in Germany in 1923 and was thus regarded as anathema for a long period afterwards. As a result, some commentators viewed quantitative easing after the financial crisis of 2007-09 with great suspicion. Technically, however, QE is not monetary financing, because central banks only buy government bonds in the secondary market and because they pay interest on reserves (the money they create).
