Argentina bonds drop as market flags intervention in peso debt

Argentina's financial markets experienced a sharp decline on Thursday, with dollar bonds leading the losses in emerging-market assets, according to wire material. The market turmoil was fueled by concerns over the government's financial health and signs that officials may have been intervening in peso bond markets to reduce borrowing costs.

The overnight repo rate surged to an annualized 190%, marking the highest level since the October 2025 midterm elections, as the market was increasingly suspicious of government interference. Analysts noted that the government seemed more focused on stabilizing the peso exchange rate over interest rates, which raised doubts about future stability.

The intervention speculation intensified after a surge in demand for local bonds the previous day, hinting at potential government participation in the market before crucial Treasury auctions. Trading volumes surged to over three trillion pesos, roughly three times the norm, before the bonds' decline resumed on Thursday. Analysts suggested the trades' scale and concentration pointed to the involvement of an official buyer, who purchased around two trillion pesos (US$1.3 billion) on Wednesday.

The intervention was speculated to lower yields ahead of the government's final debt auctions, which are slated for the following week. These auctions involve about 10.5 trillion pesos in maturities, followed by additional 66 trillion pesos in subsequent auctions. The Economy Ministry and the Central Bank did not comment on the speculation.

The turmoil impacted Argentine dollar bonds, which lagged behind other emerging markets, with some dropping two cents on the dollar. The bond curve was particularly vulnerable due to concerns about the government's ability to meet its debt obligations in 2027, with a total of roughly US$25 billion in hard-currency payments expected.

Market strategists attributed the dollar bond curve's decline to the effects of higher international rates, which further pressured Argentina's dollar bonds.
