In 2007, countries in the Euro periphery were enjoying stable growth, low deficits, and low spreads. Then the financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and, surprisingly, so did the share of the debt held by domestic creditors. Credit was reallocated from the private to the public sectors, reducing investment and deepening the recessions even further. To account for these facts, we propose a simple model of sovereign risk in which debt can be traded in secondary markets. The model has two key ingredients: creditor discrimination and crowding-out effects. Creditor discrimination arises because, in turbulent times, sovereign debt offers a higher expected return to domestic creditors than to foreign ones. This provides incentives for domestic purchases of debt. Crowding-out effects arise because private borrowing is limited by financial frictions. This implies that domestic debt purchases displace productive investment. The model shows that these purchases reduce growth and welfare, and may lead to self-fulfilling crises. It also shows how crowding-out effects can be transmitted to other countries in the Eurozone, and how they may be addressed by policies at the European level.

This paper reviews empirical and theoretical work on the links between banks and their governments (the bank-sovereign nexus). How significant is this nexus? What do we know about it? To what extent is it a source of concern? What is the role of policy intervention? The paper concludes with a review of recent policy proposals.

We analyze holdings of public bonds by over 20,000 banks in 191 countries, and the role of these bonds in 20 sovereign defaults over 1998-2012. Banks hold many public bonds (on average 9% of their assets), particularly in less financially-developed countries. During sovereign defaults, banks increase their exposure to public bonds, especially large banks and when expected bond returns are high. At the bank level, bondholdings correlate negatively with subsequent lending during sovereign defaults. This correlation is mostly due to bonds acquired in pre-default years. These findings shed light on alternative theories of the sovereign default-banking crisis nexus.

In 2007, countries in the euro periphery were enjoying stable growth, low deficits, and low spreads. Then the Financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems.

Motivated by the recent European debt crisis, this paper investigates the scope for a bailout guarantee in a sovereign debt crisis. Defaults may arise from negative income shocks, government impatience or a "sunspot"-coordinated buyers strike. We introduce a bailout agency, and characterize the minimal actuarially fair intervention that guarantees the no-buyers-strike fundamental equilibrium, relying on the market for residual financing. The intervention makes it cheaper for governments to borrow, inducing them borrow more, leaving default probabilities possibly rather unchanged. The maximal backstop will be pulled precisely when fundamentals worsen.

This paper proposes an approach to track US$1 trillion of emerging market government debt held by foreign investors in local and hard currency, based on a similar approach that was used for advanced economies (Arslanalp and Tsuda, 2012). The estimates are constructed on a quarterly basis from 2004 to mid-2013 and are available along with the paper in an online dataset. We estimate that about half a trillion dollars of foreign flows went into emerging market government debt during 2010–12, mostly coming from foreign asset managers. Foreign central bank holdings have risen as well, but remain concentrated in a few countries: Brazil, China, Indonesia, Poland, Malaysia, Mexico, and South Africa. We also find that foreign investor flows to emerging markets were less differentiated during 2010–12 against the background of near-zero interest rates in advanced economies. The paper extends some of the indicators proposed in our earlier paper to show how the investor base data can be used to assess countries’ sensitivity to external funding shocks and to track foreign investors’ exposures to different markets within a global benchmark portfolio.
