The empirical evidence is mixed on helicopter money. The well-documented historical experience of Germany in 1923, Hungary in 1946, and most recently, Zimbabwe in 2008 were disastrous. At the risk of over-simplification, the tone of the policies these countries undertook was a drastic increase in the money supply, which led to hyperinflation, and a worthless currency, and ended in a major economic recession and political turmoil.
However, other less well-known historical evidence points to the opposite conclusion. A recent case study by the Levy Economic Institute on the Canadian economy in 1935–75 concluded that the permanent monetization of debt, with no intention of unwinding later, did not produce hyperinflation or exceptionally high inflation. The huge increase in the money supply and credit engineered by the Canadian central bank was instead absorbed by a vast expansion in industrial production and employment.
In a recent article by former Federal Chairman Ben Bernanke, he said: “(Helicopter money policies) also present a number of practical challenges of implementation, including integrating them into operational monetary frameworks and assuring appropriate governance and coordination between the legislature and the central bank. However, under certain extreme circumstances—sharply deficient aggregate demand, exhausted monetary policy, and unwillingness of the legislature to use debt-financed fiscal policies—such programs may be the best available alternative. It would be premature to rule them out.”
In conclusion, we just don’t know whether or not helicopter money will work. The historical evidence has been mixed, with cases of success and failure. While helicopter money is still a low probability, we should not be surprised if some form of it gets implemented. Governor Kuroda is known for surprising the market, as he did when he introduced negative interest rates several days after signaling otherwise. It would certainly be a bold experiment from which most of the developed world would be able to learn from. The immediate knee-jerk reaction would likely be a steepening of the yield curve and a depreciation of the Japanese yen on expectations of higher inflation over the long run and an increase money supply as a result of this policy. The longer-term impact on the economy and the markets will depend on the effectiveness of this policy.
