Nobody likes taxes, so public spending frequently exceeds revenues, leading governments to borrow. These budget deficits are a flow that add to the stock of debt. Since the Great Financial Crisis of 2007-2009, public debt in a number of advanced economies has surged. In the United States. the Congressional Budget Office (CBO) recently projected that―in the absence of policy changes―federal debt held by the public is headed for record highs (as a ratio to GDP) in coming decades.
Importantly, there is a real (inflation-adjusted) limit to how much public debt a government can issue (see Sargent and Wallace). Beyond that limit, the consequences are outright default or, if the debt is in domestic currency bonds that the central bank acquires, inflation that erodes its real value leading to a partial default.
Ultimately, debt sustainability requires that a country’s ratio of public debt to GDP stabilize. Otherwise, debt eventually will rise above the real limit and trigger default or inflation. In this note, we derive and interpret a simple debt-sustainability condition. The condition states that the government primary surplus―the excess of government revenues over noninterest spending—must be at least as large as the stock of outstanding sovereign debt times the difference between the nominal interest rate the government has to pay and the rate of growth of nominal GDP. If it is not, then the ratio of debt to GDP will explode…. Read More
After years of relative calm, in recent months several emerging economies have found the cost of attracting foreign funding is going up. Faced with a halt of external financing, Argentina obtained a three-year financing deal worth $50 billion from the IMF, while funds also appear to be flowing out of Brazil, Turkey, and elsewhere. And, recent bond market turbulence in Italy suggests the possibility that political risks are triggering outflows there.
In this post, we explain balance-of-payments (BoP) crises—the sudden stops or capital flow reversals—that compel countries to restore their external balance between exports and imports or, in the case of capital flight, shift to export surpluses. In addition to describing common features of BoP crises, and characterizing sources of vulnerability that make them more likely, we examine one emerging-market example—the Asian crisis of 1997-98—and one advanced-economy episode—the crisis of the euro-area periphery from 2010 to 2012….

Last week’s 12th annual U.S. Monetary Policy Forum focused on the effectiveness of Fed large-scale asset purchases (LSAPs) as an instrument of monetary policy. Despite notable disagreements, the report and discussion reveal a broad (if not universal) consensus on key issues:
In a world of low equilibrium real interest rates and low inflation, policymakers could easily hit the zero lower bound (ZLB) in the next recession.
At the ZLB, the Fed should again use a combination of balance-sheet tools and interest-rate forward-guidance to achieve its mandated objectives of stable prices and maximum sustainable employment (see our earlier post).
Yet, significant uncertainties about the impact of balance-sheet expansion mean that LSAPs may not provide sufficient stimulus at the ZLB.
Fed policymakers should undertake a thorough (and potentially lengthy) assessment of alternative policy tools and frameworks—ranging from negative interest rates to a higher inflation target to forms of price-level targeting—to ensure they remain as effective as possible.
The remainder of this post discusses the challenges of measuring the impact of balance-sheet policies. As the now-extensive literature on the subject implies, balance-sheet expansions ease financial conditions. However, as this year’s USMPF report emphasizes, there is substantial uncertainty about the scale of that impact.... Read More
During the 2016 campaign, then-candidate Donald Trump discussed his broad experience with debt. He would bring the skills and sensibilities of a real estate mogul to government debt management, and the result would be a better deal for the American public. He even broached the idea of renegotiating the obligations of the U.S. Treasury.
Well, the day of reckoning has arrived. The Treasury has announced that by the end of September, it will face a shortfall. Without the authority to issue additional debt, the government will not be able to pay all of its bills—including the interest on the outstanding debt. In response, President Trump has threatened the Congress: either fund the wall along the Mexican border, or he will shut down the government.
If the U.S. government fails to meet its obligations for any significant period, we will all be big losers. A government that cares about the people—both now and in the future—would never willingly inflict such a wound. Read More
The Federal Reserve’s annual stress test is the de facto capital planning regime for the largest U.S. banks. Not surprisingly, it comes under frequent attack from bank CEOs who argue, as Jamie Dimon recently did, that “banks have too much capital…and more of that capital can be safely used to finance the economy” (see page 22 here). From their perspective, this makes sense. Bank shareholders, who the CEOs represent, benefit from the upside in good times, but do not bear the full costs when the financial system falters. As readers of this blog know, we’ve argued frequently that capital requirements should be raised further in order to better align banks’ private incentives with those of society (see, for example, here and here).
A more compelling criticism of central bank stress tests focuses on their discretionary character. To the extent feasible, central banks should minimize their interference in the allocation of resources by private intermediaries, allowing them to direct lending to those projects deemed to be the most productive.
But the painful lessons that have come from large asset price swings and high concentrations of risk provide a strong case for the kind of limited discretion that the Fed uses in formulating its stress tests. This blog post highlights why it makes sense for regulators to use this year's stress test exercise to learn how well the largest U.S. intermediaries would fare if the recent commercial real estate price boom were to turn into a bust....
