新兴市场债券市场评论：2026年8月
Core conclusion · Tlines extraction
In August 2026, EM debt proved resilient. Hard currency sovereigns returned +0.89% (JP Morgan EMBI GD), led by spread tightening of 10bps to ~235bps, as Treasury yields steadied at 4.75% on the 10-year. Local currency debt returned +0.90% (GBI-EM GD), driven by FX gains (+0.66%) from broad USD weakness. Flows were positive: USD1.6bn into HC and USD1.2bn into local. Short-dated bonds outperformed longer maturities year-to-date.
