    Negative Interest Rate Policies: Sources and Implications
    (World Bank, Washington, DC, 2016-08) Arteta, Carlos; Kose, M. Ayhan; Stocker, Marc; Taskin, Temel
    Against the background of continued growth disappointments, depressed inflation expectations, and declining real equilibrium interest rates, a number of central banks have implemented negative interest rate policies (NIRP) to provide additional monetary policy stimulus over the past few years. This paper studies the sources and implications of NIRP. It reports four main results. First, monetary transmission channels under NIRP are conceptually analogous to those under conventional monetary policy but NIRP present complications that could limit policy effectiveness. Second, since the introduction of NIRP, many of the key financial variables have evolved broadly as implied by the standard transmission channels. Third, NIRP could pose risks to financial stability, particularly if policy rates are substantially below zero or if NIRP are employed for a protracted period of time. Potential adverse consequences include the erosion of profitability of banks and other financial intermediaries, and excessive risk taking. However, there has so far been no significant evidence that financial stability has been compromised because of NIRP. Fourth, spillover implications of NIRP for emerging market and developing economies are mostly similar to those of other unconventional monetary policy measures. In sum, NIRP have a place in a policy maker’s toolkit but, given their domestic and global implications, these policies need to be handled with care to secure their benefits while mitigating risks.

    The Global Role of the U.S. Economy: Linkages, Policies and Spillovers
    (World Bank, Washington, DC, 2017-02) Lakatos, Csilla; Kose, M. Ayhan; Stocker, Marc; Ohnsorge, Franziska
    This paper analyzes the role of the United States in the global economy and examines the extent of global spillovers from changes in U.S. growth, monetary and fiscal policies, and uncertainty in its financial markets and economic policies. Developments in the U.S. economy, the world's largest, have effects far beyond its shores. A surge in U.S. growth could provide a significant boost to the global economy. Tightening U.S. financial conditions -- whether due to contractionary U.S. monetary policy or other reasons -- could reverberate across global financial markets, with adverse effects on some emerging market and developing economies that rely heavily on external financing. In addition, lingering uncertainty about the course of U.S. economic policy could have an appreciably negative effect on global growth prospects. While the United States plays a critical role in the world economy, activity in the rest of the world is also important for the United States.

    The Coming U.S. Interest Rate Tightening Cycle: Smooth Sailing or Stormy Waters?
    (World Bank, Washington, DC, 2015-09-15) Arteta, Carlos; Kose, M. Ayhan; Ohnsorge, Franziska; Stocker, Marc
    Since the global financial crisis, the exceptionally accommodative monetary policy stance of the U.S. Federal Reserve (Fed) has helped support activity, bolstered asset valuations, and reduced risk premia. In addition, it has been instrumental in boosting capital flows to emerging and frontier market economies (EFEs). As the U.S. economy improves, the Fed is expected to start raising policy interest rates in the near term (an event widely referred to as “liftoff”) and thus commence a tightening cycle for the first time in nearly a decade. The mid-2013 “taper tantrum” episode is a painful reminder that even a long-anticipated change in Fed policies can surprise markets in its specifics, and lead to significant financial market volatility and disruptive movements in capital flows to EFEs. Recent debates have focused on the potential impact of the liftoff on EFEs, but there are also significant risks associated with the pace of subsequent rate increases, which is currently expected to be very gradual, but could accelerate at a time when EFE policy buffers are eroding. This Policy Research Note presents a comprehensive analysis of the changes in global conditions since the taper tantrum, risks of disruptions during the upcoming Fed tightening cycle, potential implications for EFEs, and policy options.

    The Great Plunge in Oil Prices: Causes, Consequences, and Policy Responses
    (World Bank, Washington, DC, 2015-03) Baffes, John; Kose, M. Ayhan; Ohnsorge, Franziska
    This note combines and distills existing and new research to inform discussion on the topical policy issue of oil prices. Following four years of relative stability at around $105 per barrel (bbl), oil prices have declined sharply since June 2014 and are expected to remain low for a considerable period of time. The drop in prices likely marks the end of the commodity supercycle that began in the early 2000s. Since the past episodes of such sharp declines coincided with substantial fluctuations in activity and inflation, the causes and consequences of and policy responses to the recent plunge in oil prices have led to intensive debates. This paper addresses four questions at the center of these debates, with particular emphasis on emerging market and developing economies: 1) How does the recent decline in oil prices compare with previous episodes? 2) What are the causes of the sharp drop and what is the outlook for oil price? 3) What are the economic and financial consequences? 4) What are the main policy implications? The decline in oil prices will lead to significant real income shifts from oil exporters to oil importers, likely resulting in a net positive effect for global activity over the medium term. However, several factors could counteract the global growth and inflation implications of the lower oil prices. These include weak global demand and limited scope for additional monetary policy easing in many countries. The disinflationary implications of falling oil prices may be muted by sharp adjustments in currencies and effects of taxes, subsidies, and regulations on prices. Regarding fiscal policy, the loss in oil revenues for exporters will strain public finances, while savings among oil importers could help rebuild fiscal space. Lower oil prices also present a window of opportunity to implement structural reforms. These include, in particular, comprehensive and lasting reforms of fuel subsidies, as well as energy taxes more broadly.
