While fiscal conditions remain healthier than in advanced economies, emerging economies continue to be exposed to negative spillovers if global conditions were to become less favorable. This paper finds that domestic bond yields in emerging economies are heavily influenced by two international factors: global risk appetite and global liquidity. Using a novel approach, the analysis goes on to show that the vulnerability of emerging economies to these factors is not uniform but rather depends on country specific characteristics, namely fiscal fundamentals, financial sector openness and the external current account balance.

Foreign holdings of emerging markets (EMs) government bonds have increased substantially over the last decade. While foreign participation in local-currency sovereign bond markets provides an additional source of financing and reduces sovereign yields, it raises concerns about increased sensitivity of yields to shifts in market sentiment. The analysis in this paper suggests that foreign participation and an undiversified investor base transmit global financial shocks to local-currency sovereign bond markets by increasing yield volatility and, beyond a certain threshold, amplify these spillovers. These estimates are robust to a range of econometric techniques including panel smooth threshold regression.

While many studies have looked into the determinants of yields on externally issued sovereign bonds of emerging economies, analysis of domestically issued bonds has hitherto been limited, despite their growing relevance. This paper finds that the extent to which fiscal variables affect domestic bond yields in emerging economies depends on the level of global risk aversion. During tranquil times in global markets, fiscal variables do not seem to be a significant determinant of domestic bond yields in emerging economies. However, when market participants are on edge, they pay greater attention to country-specific fiscal fundamentals, revealing greater alertness about default risk.

This paper estimates the impact of foreign participation in determining long-term local currency government bond yields and volatility in a group of emerging markets from 2000-2009. The results of a panel data analysis of 10 emerging markets show that greater foreign participation in the domestic government bond market tends to significantly reduce long-term government yields. Moreover, greater foreign participation does not necessarily result in increased volatility in bond yields in emerging markets and, in fact, could even dampen volatility in some instances.

The paper investigates the international integration of EM sovereign dollar-denominated and local-currency bond markets. Factor analysis is used to examine movements in sovereign bond yields and common sources of yield variation. The results suggest that EM dollar-denominated sovereign debt markets are highly integrated; a single common factor that is highly correlated with US and EU interest rates explains, on average, about 80 percent of the total variability in yields. EM sovereign local currency bond markets are not as internationally integrated, and three common factors explain about 74 percent of the total variability. But a factor highly correlated with US and EU interest rates still explains 63 percent of the yield variation accounted for by common factors. That said, there is some diversity among EM countries in the importance of common factors in affecting sovereign debt yields.

Unconstrained multi-sector bond funds (MSBFs) can be a source of spillovers to emerging markets and potentially exert a sizable impact on cross-border flows. MSBFs have grown their investment in emerging markets in recent years and are highly concentrated—both in their positions and their decision-making. They typically also exhibit opportunistic behavior much more so than other investment funds. Theoretically, their size, multisector mandate, and unconstrained nature allows MSBFs to be a source of financial stability in periods of wide-spread market turmoil while others sell at fire-sale prices. However, this note, building on the analysis of Cortes and Sanfilippo (2020) and incorporating data around the COVID-19 crisis, finds that MSBFs could have contributed to increase market stress in selected emerging markets. When faced with large investor redemptions during the crisis, our sample of MSBFs chose to rebalance their portfolios in a concentrated manner, raising a large proportion of cash in a few specific local currency bond markets. This may have contributed to exacerbating the relative underperformance of these local currency bond markets to broader emerging market indices.
