Among the many in quantitative easing programmes that central banks have engaged in to combat low inflation since the Global Crisis, the Bank of Japan’s programme stands out for its size and scope. This column explores whether the Bank’s programme of purchasing Japanese equities through exchange-traded funds has succeeded in its aim of lowering risk premia of asset prices. The Bank has timed the execution of the programme to coincide with episodes of market weakness, possibly with the aim of dampening price volatility. Over the course of the programme, however, Japanese stocks de-rated against global stocks.

Interest rates in many advanced economies have been declining since the 1990s. This column takes a close look at the case of Japan. In 2013 the Bank of Japan pursued a policy of quantitative and qualitative monetary easing that aimed to lower the real interest rate substantially below its natural rate. The evidence suggests that this policy has had mixed success at best, and that the natural rate of interest may decline in the foreseeable future.

Portfolio rebalancing through large-scale asset purchases is one of the major transmission channels under the zero lower bound. This column assesses whether the channel has been effective in Japan, focusing in turn on financial institutions, firms, and households. Japanese firms and households are notoriously risk averse, limiting the effectiveness of the portfolio rebalancing channel. These results suggest that more drastic structural reforms and growth strategies are needed.

Communication strategies have become a policy instrument used by central banks to control expectations. This column uses a natural language processing method to explore the Bank of Japan’s communication strategy from July 2012 to November 2016, a period during which both Masaaki Shirakawa and Haruhiko Kuroda held office. The analysis suggests that since 2016, when the Bank introduced a negative interest rate policy, Kuroda's communication strategy has changed implicitly.

While non-US entities pay dollar funding premiums in the FX swap market, the US earns profits on FX-hedged investments in non-US sovereign securities. This column argues that this new form of the ‘exorbitant privilege’ presents a modern version of the ‘Triffin dilemma’. If the distributional effect of US privilege becomes large enough to induce non-US entities to take excessive risk, the stability of the global financial system will come under threat.

The Bank of Japan has been pursuing quantitative and qualitative monetary easing since 2013, but has failed to achieve its target of a stable 2% inflation rate. This column explores the Bank’s recent practices and performance, and identifies four structural factors that have contributed to the limited impact of unconventional monetary easing on aggregate demand and inflation. The Bank now needs to come up with more objective projections for the timing of achieving its price stability target.

This column, first posted 17 May 2008, reviews Willem Buiter's analysis of why the ECB is so hesitant to buy debt. Central banks can go broke – and some in developing countries have done so recently. The ECB is now lending against dubious collateral. An ECB recapitalisation seems unthinkable at the moment, but that’s why it is a good time to think the unthinkable. Willem Buiter considers the question at length in CEPR Policy Insight No. 24 and argues that Eurozone fiscal authorities should, ASAP, agree on a formula for fiscal burden-sharing should an ECB recapitalisation ever be necessary.
