Public debt managers typically face some level of uncertainty stemming from changes in funding needs, as well as in the funding environment. Government funding requirement, which is submitted to debt management offices, is subject to changes during a fiscal year partly due to deviations between forecast and actual budget expenditures and revenues. In the OECD area, governments funding needs are predominantly financed through financial markets. Therefore, a deterioration in market sentiment due to various factors including political events, macroeconomic developments, and monetary policy decisions, has a strong impact on public debt management. Public debt managers, striving to be predictable, regular and transparent issuers in the market, consider a “typical” level of uncertainty (i.e. level of uncertainty observed in normal times), when they develop funding programmes.
When undesirable changes occur in funding needs and funding conditions at the same time, this might dampen investors’ appetite significantly, which in turn poses a danger for government financing depending on the size and duration of the volatility. That said, the borrowing environment for governments could become more difficult than usual due to increasing funding pressures coinciding with sudden shifts in sentiment and perceptions of sovereign risk. The 2013 edition of the Sovereign Borrowing Outlook discussed how occasional destabilising dynamics of government securities markets creates huge policy problems including loss of market access.2 During the debt crisis in 2010-2012, significant sales of sovereign debt by foreign and domestic investors together with soaring borrowing needs, resulted in a surge in interest rates demanded by bond investors to very high levels in several countries. The borrowing environment for governments became difficult due to the complications generated by sudden shifts in sentiment and perceptions of risk associated with certain sovereigns: the so-called swings in the “risk-on” and “risk-off” trades. It is highlighted that these sharp and significant price deviations relative to fundamentals led to interruptions in government’s market access and even loss of market access in some cases. The empirical literature has explored the issue of a self-fulfilling prophecy on various occasions in terms of the potential implications of debt dynamics on market access conditions (see, among others, Reinhart et al. 2003; Kraay and Nehru 2006; Manasse and Roubini 2009; Ghosh et al. 2012; and Bassanetti Antonio, et al. 2016).
Looking back, the global financial crisis, and the policy response to it, implied drastically increased additional borrowing requirements across the OECD area. As discussed in previous editions of this publication, the legacy of the financial crisis continues to cast a long shadow over public finances, in the form of high debt burdens and heavy debt repayments. Gross borrowings of OECD governments from the markets, which peaked at USD 10.9 trillion in 2010 in the wake of the financial crisis, are set to reach a new record level in 2019, when they are expected to exceed USD 11 trillion. As a result, central government debt-to-GDP ratios in OECD countries remain above 70% (and close to 90% in G7 countries), which is high by historical standards. In terms of refinancing of existing debt, sovereigns in the OECD area need to roll over 40% of their outstanding marketable debt in the next three years.
While crisis-related legacies remain in some countries, monetary policy transition in major markets, escalating trade tensions, and heightened geopolitical risks might pose challenges going forward for financial markets. Indeed, the recent bouts of volatility in financial markets, in conjunction with slower and less balanced economic growth expectations in the OECD area have raised market concerns over sovereigns’ ability to repay their debt and put extra pressure on sovereign funding conditions in some countries. It is, therefore, timely to look back and assess the challenges faced during the European sovereign debt crisis, and to highlight key lessons learned from the experiences with stressed market conditions.
Country experiences presented in the following sections of this chapter suggest similarities as well as differences in losing, and re-establishing market access. Significant sales of sovereign debt by foreign and domestic investors, coupled with soaring borrowing needs often result a surge in interest rates to very high levels. Public debt managers often shorten maturities of new debt (issuing T-Bills) to weather storms. Hence, the stressed market conditions initially manifest themselves with a sudden hike in interest rates and decline in maturities of borrowing instruments. This was the case in Greece, Iceland, Ireland and Portugal during the European sovereign debt crisis. As market conditions have improved in recent years, there has been a significant improvement in maturity of new debt issuance, which in turn helped mitigating refinancing risk in these countries (Figure 3.1).
