As the Eurozone crisis lingers on, euro exit is now being debated in ‘core’ as well as ‘periphery’ countries. This column examines the potential costs of euro exit, using France as an example. The authors estimate that 30% of private marketable debt would be redenominated, but since only 36% of revenues would be redenominated, the aggregate currency mismatch is relatively modest. However, the immediate financial cost of exiting the euro would nevertheless be substantial if public authorities were to bail out systemic and highly exposed companies.

There has been renewed interest in sovereign debt since the Global Crisis, but relatively little attention has been paid to its composition. Sovereign debt can differ in terms of the currency it is denominated in, its maturity, its marketability, and who holds it – and these characteristics matter for debt sustainability. This column presents evidence from a new dataset on the composition of sovereign debt over the past century in 13 advanced economies.

The landscape of portfolio investment in emerging markets has evolved considerably over the past 15 years. Financial markets have deepened and become more internationally integrated. The mix of global investors has also changed, with more money intermediated by mutual funds. This column explains that these changes have made capital flows and asset prices in these economies more sensitive to global financial shocks. However, broad-based financial deepening and improved institutions can enhance the resilience of emerging-market economies.

In recent years credit growth in Latin America has been very strong, and countries have become more reliant on foreign bond issuances. This column argues that these phenomena are linked, and may have led to vulnerabilities which domestic and international supervisors are not well-equipped to assess. There is no systematic information on firms’ currency mismatches and hedging activities, and none that includes those of subsidiaries that may be located in other jurisdictions, preventing an accurate analysis of the true risks.

Is “original sin”, a situation in which the domestic currency is not used to borrow abroad or to borrow long-term even domestically, no longer a problem? This column argues that, while original sin has diminished and countries are making greater use of their domestic bond market, foreign currency debt is still too risky to be sensible.
