How could global market volatility hit Argentina?

Global market volatility could impact Argentina through multiple avenues. The Federal Reserve Chair's recent speech at the Jackson Hole conference hinted at a possible rate hike after a prolonged period of inactivity, raising the likelihood of a 25 basis point increase during the Fed's September meeting. This potential rate hike has increased the probability to 68% according to CME Group's FedWatch tool.

Simultaneously, the resurgence of tensions between the U.S. and Iran has driven up global oil prices, sending Brent crude above US$91 a barrel. This price surge has reignited concerns about its implications for global inflation. As a result, the demand for Treasuries has decreased, causing significant selling pressure and driving up yields, including the 10-year note to a 4.79% level, which is the highest since January 2025.

If the Fed proceeds with the imminent rate hike, Argentina would likely experience higher borrowing costs in international debt markets, which could be a major concern given the recent rise in country risk. In July, JPMorgan's EMBI+ index for Argentina, which measures the interest rate Argentina pays to borrow abroad, hit 402 basis points, its lowest level since April 2018.

Since then, it has climbed to over 500 basis points. Moreover, with higher U.S. interest rates, investing in U.S. Treasuries becomes more attractive and less risky compared to emerging markets like Argentina. This shift could negatively affect the price of Argentine bonds and strengthen the dollar on international markets, making Argentine debt, which is largely denominated in dollars, more expensive to service.

Economists warn that this hawkish tone from the Federal Reserve presents a significant challenge for global fixed income, especially in higher-beta emerging countries such as Argentina. Higher-beta countries refer to developing economies with financial markets that are highly sensitive and volatile compared to global markets, a characteristic Argentina shares.

Although some economists suggest that the current market situation might not necessarily lead to a bearish trend, they agree that Argentina and other energy exporters could face heightened challenges due to the increased volatility and the need for more precise asset differentiation.
