Frontier market bonds the new edge in EM debt

Every so often, something comes along in markets that looks small on the surface but quietly tells you where an asset class is heading. J.P. Morgan's new GBI-EM Edge Index is one of those moments. For the first time, frontier local-currency debt has a benchmark to call its own. We think that's worth your attention, because the implications run well beyond the launch of yet another index.

A quick recap 

Frontier markets sit one step back in the development journey from mainstream emerging markets. Their economies and financial markets tend to be smaller and less mature, with lower liquidity and less-established political, governance and regulatory frameworks.

But many also offer attractive long-term growth potential, supported by young populations, expanding workforces and important roles in global supply chains and resource production. Risks can be higher and conditions vary significantly between countries, making careful country selection particularly important.

Why a benchmark matters

For years, frontier economies have drawn a surprisingly small share of global capital, and part of the reason was simply practical: investors had no common yardstick for performance, risk or relative value. GBI-EM Edge helps fix that. It pulls together roughly US$328 billion of debt across 26 markets at an average yield of around 10.4%, some 440 basis points above the mainstream EM local-currency benchmark¹. A recognised reference point makes it far easier to treat frontier local debt as a distinct allocation rather than a niche afterthought.

The growth of the underlying market is also notable. At inception in 2017, the index comprised 11 markets and 76 bonds, representing approximately US$56 billion of debt². Today, market coverage has roughly doubled, while total eligible issuance has grown almost six-fold, highlighting how quickly this part of the EM fixed-income universe has developed.

Why it matters for capital markets

Benchmarks also have a way of changing behaviour. As these markets gain visibility, governments tend to respond by improving access, liquidity and infrastructure to attract a wider investor base – Kazakhstan's recent reforms and rising foreign participation are a good example. Over time, that can help countries fund themselves more in local currency and lean less on external debt.

There's a portfolio angle too. Our own analysis suggests that adding a 15% frontier sleeve to a mainstream local-currency index could cut volatility by close to a full percentage point – a reminder of the genuine diversification these markets can offer³.

Final thoughts…

GBI-EM Edge may be just an index, but its significance goes further. A recognised benchmark gives frontier local debt greater visibility, makes the asset class easier to assess and could ultimately help attract more international capital. 

Welcome to the new frontier. 

For investors, that matters. Frontier markets are growing, becoming more accessible and increasingly offer something genuinely different from mainstream emerging-market debt. The edge, perhaps, is no longer quite so far from the mainstream.
