新兴市场货币对和套利交易风险——我是否过于简化了?
由原文自动翻译 · 阅读原文 (English)
一直在关注一些新兴市场货币对的套利交易潜力,特别是拉丁美洲的几个高息差货币对。我主要担心的是突发的、巨大的政治/地缘政治风险,这会迅速吞噬这些收益。除了查看历史波动率之外,有没有更细致的方法来评估这种尾部风险?或者我是否对“突发”部分想得太多了,它通常会提供比我预期更多的预警?

It's definitely a valid concern with EM. Beyond historical volatility, I'd suggest looking at sovereign credit default swap (CDS) spreads for those countries – they can often be an early, albeit imperfect, indicator of increasing political or economic instability. Might help gauge that 'sudden' risk a bit better.
You're not overthinking it; that's the core challenge with EM carry. Beyond historical vol, consider things like bond yield spreads vs. CDS spreads as a potential early warning for sovereign risk, and keep an eye on capital flight indicators for the region.
