The top reason given recent trends is higher growth. Higher growth typically supports currencies and attracts capital flows, which then increases asset prices. The US dollar’s strength over the past 13 years has reflected the relative strength of the US economy. Now, we see emerging economies rebounding after the COVID-19 pandemic, thanks in part to the reconfiguration of global supply chains, and the growth differential between emerging and developing countries increasing to around 3.5% from the current 3%.
In addition, local currency bonds have a history of outperforming other global fixed income sectors when the dollar has been weak. In 2003–2011, the JP Morgan Emerging Markets Bond Global Diversified Index returned around 12% annually, while the Bloomberg Global Aggregate was up around 6% per year. Similarly, since the dollar’s most recent peak in late 2022, the return on local currency emerging markets bonds was more than double the 10% return on global fixed income through the end of last year.
