Inflation and Fiscal Policy

Why is it proving so difficult to raise inflation? For generations after World War II, this was not something that worried economists. Yet, today, even as central banks lower policy rates close to zero (or below) and expand their balance sheets beyond what anyone previously imagined possible (see chart), inflation remains stubbornly below target in most of the advanced world.

Nowhere is this problem more profound than in Japan, where mild deflation was the norm for nearly two decades and where inflation still remains well shy of the Bank of Japan’s 2% target. Even as monetary policymakers expanded the central bank’s balance sheet by nearly one-third of GDP and nudged its policy rate slightly below zero, consumer price inflation (as measured by our preferred trend measure, the 10% trimmed mean) has slipped from 0.9% to 0.1% over the two years to July 2016...

Saving for retirement

The biggest question facing anyone considering retirement is financial: are my savings sufficient to provide for my lifestyle for the rest of my life? For the fortunate among us, the answer is yes. But for a large fraction of the population, the answer is likely no.

The typical U.S. household has few retirement savings. The National Institute on Retirement Security reports that the median for near-retirement households is $12,000, while that for all households is only $3,000. Most people are relying on government social security to meet their retirement needs.

There are many reasons for this. One is the reduction in the fraction of employers offering any retirement plan at all, and another is the shift away from defined-benefit (DB) and toward defined-contribution (DC) pension plans. The result is that many individuals face risks that they are not equipped to bear, and many households need to save substantially more than they would have had these changes not occurred....

Opportunities in Finance

“We’re really only at 1% of what is possible, and probably even less than that. […] We should be building great things that don’t exist.”     Larry Page, Google I/O 2013 Keynote

With the summer coming to an end, professors everywhere are greeting a new group of students. So, our thoughts turn to the opportunities and challenges that those interested in finance will face over the course of their careers.

Like many important activities, finance is constantly evolving, so the “facts” that students learn in classes today will almost certainly change rapidly. With that in mind, we always strive to find a set of core principles that will endure, so that students can build a career based both on a set of specialized skills and on a broad capacity to imagine where finance and the financial system are heading...

Negative Nominal Interest Rates (again)

There is an obsession with negative nominal interest rates. People seem to think that they make no sense. And, there is a fixation with keeping track of the fraction of sovereign debt that is trading at negative nominal rates. (At this writing, the number is approaching one-third of the total outstanding.) Clearly many central bankers believe that setting the policy rate below zero is a legitimate use of this conventional instrument, a point that we have supported in the past. But the fact that people are so disturbed prompts us to ask why. In this post, we first discuss why we are confused by this reaction, and then try to identify what might account for it....

The FOMC's Prudent Caution

Imagine Fed Governor Rip van Winkle waking from a 10-year nap to find that trend inflation is only a bit shy of the 2% target, the unemployment rate is close to its long-run steady state, and the Fed’s balance sheet is five times larger than when he fell asleep. As we wrote two years ago, you could forgive him for expecting the federal funds rate to be closer to 4% than ½%. And, you would understand his astonishment when he learns that financial market expectations of policy tightening have collapsed amid continued economic expansion.

So, why are both the current policy rate and expectations of the future rate so low? There are four powerful reasons. First, both investors and policymakers have lowered their estimates of the steady-state (or “natural”) real interest rate. That means that Fed policy today is less accommodative than Governor Rip’s 10-year-old perspective leads him to think. Second, Rip is surely startled to learn that, even with a tightening labor market and policy rates close to zero, market-based long-run inflation expectations have declined. Third, it seems unlikely that Rip would be thinking much about the policy asymmetry that occurs when the nominal interest rate is near the effective lower bound. That is, as post-crisis experience suggests, with policy rates near (or even below) zero, it is much easier for central banks to tighten when prices rise too quickly than it is to ease should prices start to fall. Fourth, the economy’s productive capacity may be endogenous: that is, it may be possible for trend growth to be higher than recent experience suggests...

Are European Stress Tests Stressful Enough?

We are huge fans of stress tests. In many ways, they are the best macroprudential tool we have for reducing the frequency and severity of financial crises.

The idea behind stress tests is simple: see if all financial institutions can simultaneously withstand a major negative macroeconomic event—a big fall in real output, a large decline in equity and property prices, a substantial widening of interest-rate spreads, an adverse move in the exchange rate. And, importantly, assume that in response to these adverse circumstances banks have no way to sell assets or raise equity. That is, the stress test asks whether each intermediary can stand on its own without help in the middle of an economic maelstrom. But for stress tests to be effective, they must be truly stressful. The tempest has to be the financial equivalent of a severe hurricane, not just a tropical storm.

This brings us to the latest European Banking Authority (EBA) 2016 stress tests. As we mentioned recently, the European financial system may be the biggest source of systemic risk globally. So, these tests are important not just for Europe, but for the world as a whole. Unfortunately, they just aren’t severe enough, so there is little reason to be confident about the resilience of European finance...

The World of ETFs

The first U.S. exchange-traded fund (ETF)—the SPY based on the S&P500—began trading in 1993. Since then, the number of such funds has grown dramatically, so that by mid-2016 there were more than 1,600 ETFs on U.S. exchanges valued at roughly $2.2 trillion. This means that ETFs are now roughly one-sixth the size of open-end mutual funds. And, with this ETF growth has come a broadening in their scope and character. Today, there are ETFs that include less liquid assets such as corporate bonds and emerging market equities, and there are funds that provide inverse or leveraged exposure to the underlying assets.

Given these trends, it is no surprise that ETFs have attracted regulators’ attention (see, for example, here and here). Should they be concerned? Is this a consumer protection issue? Do ETFs contribute to systemic risk? Or, is their design stabilizing? Might financial stability even be served by the conversion of all open-end mutual funds into ETFs? ...

The Lender of Last Resort and the Lehman Bankruptcy

Professor Larry Ball, our friend and colleague, has written a fascinating monograph reexamining the September 14, 2008 failure of Lehman Brothers. Following an exhaustive study of documents from a variety of sources, Professor Ball concludes that the Fed could have rescued Lehman. The firm had sufficient collateral to meet its liquidity needs, and may have been solvent. The implication is that the worst phase of the financial crisis was preventable. (A short summary is available here.)

We are skeptical on several fronts—that Lehman was solvent, that policymakers had authority to lend to an insolvent institution, and that doing so would have limited the financial crisis...

The China Debate

China’s rapid credit expansion is worrying. Will Chinese policymakers be able to contain the growth of credit without undermining economic growth and without triggering a banking or currency crisis? Aside from the consequences of Brexit, this is probably the most important issue facing global policymakers and investors today.

As it turns out, there are powerful arguments on both sides. The positives—high national savings and returns to investment, combined with the government’s broad tools for intervention—must be measured against a set of negatives—growing loan losses, the spread of shadow banking, large capital outflows, falling investment returns, and declining confidence in the government’s financial policy management. Against this complex background, it is no wonder that concerns and uncertainty are both high. What one can say confidently remains conditional:  things are very likely to end badly if the credit buildup continues amid slowing economic growth...

Brexit Stress Test

The U.K. Brexit referendum is providing us with the first significant test of our sparkling new regulatory system. Everyone knew about the referendum months in advance, giving them plenty of time to prepare. Yet, we are left with some fundamental questions related to global financial stability. Do banks have sufficient capital and liquidity to withstand the “shock?” Will financial markets continue to serve their key functions?  Or, is the financial system only as strong as its weakest link? Will turmoil once again prompt liability holders to run, triggering asset fire sales, and compelling central banks once again to do whatever it takes to keep avert a meltdown?

As the rating agencies might say, we are on “stress watch” with a negative outlook. Or, to mix metaphors, numerous lights are flashing yellow, so we are worried...
