Macro scorecards for local-currency EM bonds
The EM local-currency opportunity
Emerging market local-currency sovereign bonds offer attractive yields and diversification benefits, but selecting among 20+ countries requires a disciplined framework. Ad hoc country analysis is resource-intensive and often influenced by recency bias. We propose a systematic scorecard approach that distills the macro outlook for each country into a quantitative composite score.
The scorecard framework is built on the principle that sovereign bond returns in local currency are driven by three forces: the level and direction of real yields, the trajectory of inflation, and the sustainability of external balances. Each dimension is measured using point-in-time data from the JPMaQS system.
Scorecard construction
For each country, we compute sub-scores across four dimensions: growth momentum, inflation dynamics, external vulnerability, and policy credibility. Growth momentum captures the direction and acceleration of economic activity. Inflation dynamics measure the gap between realized and expected inflation. External vulnerability assesses current account positions and reserve adequacy. Policy credibility combines central bank track record with fiscal discipline indicators.
Sub-scores are standardized within each dimension's historical distribution and combined into a single composite using volatility-adjusted weights. The resulting scorecard assigns each country a percentile ranking that updates as new data arrives.
Strategy performance
A long-short strategy that goes long bonds in the top-scoring countries and short the bottom-scoring countries generates a Sharpe ratio of 0.71 over the evaluation period. The strategy captures approximately 60% of the returns available from perfect foresight, a high information coefficient by the standards of macro factor strategies.
The scorecard is particularly effective at avoiding distressed credits: countries that eventually experience sovereign stress events consistently rank in the bottom quartile of the scorecard 6-12 months before the event crystallizes.
Use in portfolio management
Beyond long-short strategies, the scorecard serves as a risk management overlay for benchmark-aware EM bond portfolios. Portfolio managers can use the scores to tilt allocations within tracking error budgets, or to flag positions where the macro outlook has deteriorated significantly relative to spread compensation. The framework's transparency makes it suitable for institutional governance and client reporting.
