Despite a major geopolitical shock, Emerging Market currencies have held up remarkably well. In contrast, EM rates markets have shown significant stress, indicating painful positioning squeezes and a reassessment of inflation risks by investors. This divergence signals underlying strength in some areas but reveals hidden fragilities in others.

The current US rates sell-off is characterized by rising real yields rather than just higher inflation expectations. This specific type of move is the most damaging for emerging markets because it tightens global financial conditions, making it difficult for EM rates to decouple from US pressure.

While emerging market sovereign credit spreads have widened only slightly, the real threat to lower-rated countries comes from the sharp sell-off in US Treasuries. This pushes the total 'all-in' borrowing yield significantly higher, threatening market access for frontier markets even if their specific risk premium remains contained.

When central banks globally tighten monetary policy in a synchronized response to shared cyclical and inflationary pressures, the negative impact on Emerging Market currencies is cushioned. The relative nature of the FX market means no single currency bloc is uniquely disadvantaged.

Recent increases in emerging market rates are accompanied by flattening or stable long-end yield curves. This suggests markets are pricing in central bank rate hikes to control inflation, rather than reacting to worsening fiscal concerns, which would typically cause the curve to steepen.

Initially, rising EM yields were almost entirely driven by higher U.S. Treasury yields, not increased credit risk. This has shifted; spreads are now widening independently as global growth concerns mount, indicating the market is finally pricing in a genuine credit risk premium.

The traditional correlation where rising rates hurt Emerging Market currencies is breaking down. Strong, synchronized global growth and a multi-year trend of EM growth upgrades are supporting EMFX. This dynamic allows currency carry trades to perform well even as local bond markets sell off due to higher rates.

The market has already priced in the hawkish Federal Reserve. The most recent volatility and sell-off in emerging market rates are not driven by US monetary policy but almost entirely by soaring energy prices and the geopolitical uncertainty surrounding them.

While emerging market sovereign credit spreads remain near historic lows, the all-in yield has risen sharply due to the repricing of US rates. This increases the real cost of borrowing and refinancing for riskier sovereigns, a danger that isn't immediately apparent from looking at spreads alone.
