MIAMI – When it comes to sovereign debt, the term “default” is often misunderstood. It almost never entails the complete and permanent repudiation of the entire stock of debt; indeed, even some Czarist-era Russian bonds were eventually (if only partly) repaid after the 1917 revolution. Rather, non-payment – a “default,” according to credit-rating agencies, when it involves private creditors – typically spurs a conversation about debt restructuring, which can involve maturity extensions, coupon-payment cuts, grace periods, or face-value reductions (so-called “haircuts”).
If history is a guide, such conversations may be happening a lot in 2016.
Like so many other features of the global economy, debt accumulation and default tends to occur in cycles. Since 1800, the global economy has endured several such cycles, with the share of independent countries undergoing restructuring during any given year oscillating between zero and 50% (see figure). Whereas one- and two-decade lulls in defaults are not uncommon, each quiet spell has invariably been followed by a new wave of defaults.
The most recent default cycle includes the emerging-market debt crises of the 1980s and 1990s. Most countries resolved their external-debt problems by the mid-1990s, but a substantial share of countries in the lowest-income group remain in chronic arrears with their official creditors.
