Today’s Focus
Argentina’s main stock index, the S&P Merval, rose 0.69% to 2,855,486 points on Thursday 15 October after losses in the morning. Infobae, citing the daily market summary, said it recovered as Wall Street rebounded.
The country-risk index, which measures the extra yield investors demand on Argentine dollar bonds, rose to 622 basis points. It touched 640 during the session and rose for a fifth straight day, Infobae reported.
US investors hold Argentina through ADRs and the ARGT fund, which rose 1.05% to US$87.90. The split between rising shares and weaker bonds is the main feature of the day.
What matters today. Rising shares alongside rising country risk shows that equity investors and bond investors read the same day differently, a pattern US holders of Argentine debt should watch.
01 The session in one read
The Merval ended at 2,855,486.21, a gain of 0.69% from Wednesday’s close of about 2,835,843. Trading Economics shows a slightly different close of 2,859,051, up 0.82%, so we use the figure published by the Buenos Aires summary.
Shares of Argentine companies traded in New York mostly rose. Globant led with 6.4%, followed by Supervielle at 4.9%, Grupo Financiero Galicia at 2.59% and Banco Macro at 1.94%.
YPF, the state-linked oil company, was the notable loser, falling 2.18% to US$51.11.
Assessment — Shares and bonds diverge MEDIUM
Equities gained while country risk rose for a fifth straight day. That suggests bond investors reacted to higher US yields and local uncertainty, while stock buyers followed Wall Street.
The cause of the bond weakness is not fully clear from the day’s data.

03 Why it moved: Wall Street’s recovery
Infobae said the Merval turned positive in the afternoon as US stocks recovered, with the Dow Jones up 1.08% and the S&P 500 up 0.33%. Argentine shares trade closely with their New York listings.
Bonds had a harder day because yields on US debt remain high after Wednesday’s inflation report. Higher US yields raise the cost of borrowing for emerging markets such as Argentina.
04 The day’s movers
| Stock (New York shares) | Note | Change |
|---|---|---|
| Globant | Software services | +6.40% |
| Banco Supervielle | Bank | +4.9% |
| Grupo Financiero Galicia | Bank | +2.59% |
| Banco Macro | Bank | +1.94% |
| Mercado Libre | E-commerce and payments | +0.97% |
| YPF | Oil and gas | -2.18% |
The banks gained as a group, which is typical on days when Wall Street rises. YPF fell even though the USO oil fund rose 2.44%.
05 The regional scoreboard
Argentina was the second-best of the five main Latin American markets. Mexico’s IPC rose 1.31%, Chile’s IPSA 0.05%, Colombia’s COLCAP edged down and Brazil’s Ibovespa fell 1.06%.
The ILF fund, which tracks large regional companies, fell 0.83%.
06 The outlook
The key question is whether country risk can stabilise below 640 basis points. A sixth rise would suggest that the bond market, not the stock market, sets the tone.
Politics matter too, since the next presidential election is the longer-term driver. Prediction markets currently favour the president.
What Prediction Markets Say
Polymarket, a prediction market, priced Javier Milei at 49.5%, Axel Kicillof at 31.5% and Sergio Massa at 16.1% to win Argentina’s next presidential election, with US$905,990 traded (read at 8:24 pm ET on 15 October). It priced the chance that Milei leaves office before 2027 at 2.5% (US$167,491 traded).
These prices are bets, not polls, and they can move quickly on new events.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- Country risk: A move above 640 basis points would confirm bond-market stress, while a fall below 600 would signal calm.
- Fiscal data: Argentina’s September budget balance is due on Friday 16 October at 15:07 UTC, with the previous reading at 1,990.
- US yields: Higher US yields would pressure dollar bonds again.
- The peso: Watch whether USD/ARS stays near 1,513.
