The challenges that are under the spotlight globally can be grouped into two issues: (i) low inflation and related impacts of unconventional monetary policy, as well as policy coordination including fiscal stimulus, and (ii) the wide range of recent issues related to central bank money (cash), private money (bank deposits), emergence of private crypto assets, and threats posed by Facebook’s Libra plan, as well as the prospect of a central bank digital currency. The first challenge is related to persistently low inflation observed in some developed economies even after various unconventional monetary easing tools have been adopted for many years when short-term interest rates have fallen into the efective lower bound. Employment conditions have improved remarkably, stock and real estate prices have risen, and currency depreciation has occurred in some economies. Nonetheless, inflation has remained below the numerical inflation target for most of the time since the 2008 financial crisis. Inflation underperformance has been prevalent in the euro area, Japan, and, to a lesser extent, the United States. Various unconventional monetary easing tools—such as large-scale asset purchases, forward guidance, negative interest rate, yield curve control, stock exchange-traded fund (ETF) purchases— have been experimented with by several central banks. It appears that many central banks prefer forward guidance and large-scale asset purchases to a negative interest rate. Yield curve control (stabilizing the short-term policy rate and a 10-year yield), adopted by the Bank of Japan since 2016, is receiving attention from some central banks. The Reserve Bank of Australia followed the Bank of Japan in March 2020 by attempting to stabilize a shorter 3-year yield. The United States Federal Reserve has been discussing the possible adoption of yield curve control focusing on a shorter maturity like the Reserve Bank of Australia. ETF purchases are so far conducted only in Japan. It is uncertain how long unconventional monetary easing will continue in the low inflationary environment although various adverse impacts are growing. Given the weak outcomes of unconventional monetary policy tools to raise inflation, furthermore, alternative monetary frameworks— such as average inflation targeting and price-level targeting—and policy coordination using fiscal stimulus have been intensively discussed in !1 2!Growing Central Bank Challenges in the World and Japan the central banking circle especially at the Federal Reserve and in academia. Moreover, the weaker relationship between unemployment and inflation—called a “flattened Phillips curve”—has invited various arguments. The Phillips curve also applies to the relationship between the output gap (namely, the diference between actual and potential output or, simply, the supply-demand balance) and inflation. Some central banks claim that the flattened Phillips curve indicates the successful outcome of flexible inflation targeting since inflation has become less reactive to changes in the unemployment gap (the gap between the current rate of unemployment and the natural rates of unemployment) and more reactive to long-term inflation expectations. However, persistent inflation underperformance calls into question whether this view remains valid. It may suggest that inflation expectations have dropped and are no longer well-anchored at around the inflation target. The flattened Phillips curve might also mean the relationship between unemployment and inflation has weakened. If this is true, this generates a challenging environment for some central banks since they may find it difcult to provide accurate inflation forecasts. The second challenge this book deals with is issues related to money, crypto assets, and central bank digital currency. Cash demand (beyond nominal gross domestic product [GDP]) grew after the global financial crisis of 2008–2009 in some developed economies—including the euro area, Japan, the Republic of Korea, Singapore, the United Kingdom, and the United States—despite cashless payment tools gaining popularity.
