The risk from a potential US diesel export ban extends beyond countries directly importing from the US. It would disrupt the entire global product market, creating price pressures for any emerging market nation reliant on refined product imports, regardless of their primary supplier.
Key emerging market indicators, like GBI-EM yields and EMFX performance, have recently moved more than one standard deviation from their norms. This suggests the "reflationary" investment theme (higher yields, strong FX) is priced to perfection, increasing uncertainty and the risk of a market reversal.
The underperformance in EM high-yield credit is not a uniform flight to safety. It's a mixed bag driven by specific stories (e.g., Argentina) and heavy positioning. This is evidenced by the simultaneous outperformance of other distressed, high-yield names like Pakistan and Sri Lanka, even though they are oil importers.
EM corporate credit has been highly resilient to external pressures like rising US Treasury yields, with spreads reaching 15-year tights. However, the asset class is not immune to stress. The primary source of recent defaults has been high local interest rates in specific countries, such as Brazil, rather than global factors.
Investors show widespread comfort with stable EM fundamentals and supportive technicals but lack conviction on major macro themes like rates and geopolitics. This divergence explains why investors remain in EM spread products to collect carry, despite tight valuations, rather than making large directional bets.
