How Much Finance Is Too Much: Stability, Growth & Emerging Markets


By Ratna Sahay, Martin Čihák, and Papa N’Diaye 

The world still lives in the shadow of the global financial crisis that began in the United States in 2008.  The U.S. experience shone a spotlight on the dangers of financial systems that have grown exponentially and beyond traditional banks. It triggered a rethinking of the extent and speed of the expansion of a country’s financial sector, and raised questions about which policies promote a safe financial system.

In our new study, we emphasize that the most commonly used indicator—bank credit—is not sufficient to measure the size and scope of a country’s financial development. We create a comprehensive index for over 170 countries to answer several policy questions from the perspective of emerging markets.

Financial Risks Rise Amid Uneven Global Economic Recovery


GFSR

By José Viñals

(Versions in عربي and Español)

The three main messages from this Global Financial Stability Report are:

  1. Risks to the global financial system have risen since October and have rotated to parts of the financial system where they are harder to assess and harder to address.
  2. Advanced economies need to enhance the traction of monetary policies to achieve their goals, while managing undesirable financial side effects of low interest rates.
  3. To withstand the global crosscurrents of lower oil prices, rising U.S. policy rates, and a stronger dollar, emerging markets must increase the resilience of their financial systems by addressing domestic vulnerabilities.

Let me now discuss these findings in detail.

Taper Tantrum or Tedium: How U.S. Interest Rates Affect Financial Markets in Emerging Economies


By Alexander Klemm, Andre Meier, and Sebastián Sosa

(Version in Español)

Governments in most emerging economies, including in Latin America, have reduced their exposure to U.S. interest rates over the past decade, by issuing a greater share of public debt in domestic currencies.

Even so, sudden changes in U.S. interest rates still have the power to roil financial markets in emerging economies. Witness last year’s “taper tantrum”—when the Fed hinted at the possibility of tapering its bond purchases sooner than previously expected, causing bond yields to rise sharply. Continue reading

Are Banks Too Large? Maybe, Maybe Not


By Luc Laeven, Lev Ratnovski, and Hui Tong

Large banks were at the center of the recent financial crisis. The public dismay at costly but necessary bailouts of “too-big-to-fail” banks has triggered an active debate on the optimal size and range of activities of banks.

But this debate remains inconclusive, in part because the economics of an “optimal” bank size is far from clear. Our recent study tries to fill this gap by summarizing what we know about large banks using data for a large cross-section of banking firms in 52 countries.

We find that while large banks are riskier, and create most of the systemic risk in the financial system, it is difficult to determine an “optimal” bank size. In this setting, we find that the best policy option may not be outright restrictions on bank size, but capital—requiring  large banks to hold more capital—and better bank resolution and governance.

Global Financial Stability: Beginning To Turn The Corner


GFSRBy José Viñals

(Version in  EspañolFrançaisРусский中文 and 日本語)

 

Global financial stability is improving—we have begun to turn the corner.

But it is too early to declare victory as there is a need to move beyond liquidity dependence—the central theme of our report—to overcome the remaining challenges to global stability.

Progress

We have made substantial strides over the past few years, and this is now paying dividends.  As Olivier Blanchard discussed at yesterday’s press conference of the World Economic Outlook, the U.S. economy is gaining strength, setting the stage for the normalization of monetary policy.

In Europe, better policies have led to substantial improvements in market confidence in both sovereigns and banks.

In Japan, Abenomics has made a good start as deflationary pressures are abating and confidence for the future is rising. And emerging market economies, having gone through several recent bouts of turmoil, are adjusting policies in the right direction.

The Evolution of Monetary Policy: More Art and Less Science


By Giovanni Dell’Ariccia and Karl Habermeier

(Versions in Español)

The global financial crisis shook monetary policy in advanced economies out of the almost complacent routine into which it had settled since Paul Volcker’s Fed beat inflation in the United States in the early 1980s.

Simply keep inflation low and stable, target a short-term interest rate, and regulate and supervise financial institutions, the mantra went, and all will be well.

Of course many scholars and policymakers, especially in emerging markets, were skeptical of this simple creed. But they did not make much headway against a doctrine seemingly well-buttressed by sophisticated theoretical models, voluminous empirical research, and over 20 years of “Great Moderation” —low inflation and output volatility. All of that has changed since the crisis, and ideas that were once marginal have now moved to center stage.

U.S. Monetary Policy and Its Effects on Latin America


Alejandro WernerBy Alejandro Werner

(Version in Español and Português)

Some basic realities seem to be getting lost in the debate over the Fed’s “exit” from unconventional monetary policy and its impact on Latin America.

First, the still-loose stance makes sense. U.S. inflation is too low, the output gap too large, and the labor market too weak. And even during tapering, the Fed’s stance will remain highly loose. The 10-year Treasury rate, adjusted for core inflation, is about 230 basis points below its 30-year average and the inflation-adjusted Fed funds rate is 320 basis points below. These rates are likely to remain below their 30-year average for at least the next two to three years.
