Argentina’s Peso Stabilizes Amid Post-Election Optimism and U.S. Support

Buenos Aires – The Argentine peso exhibited resilience against the U.S. dollar on October 31, 2025, with the official exchange rate holding at approximately 1,439.44 pesos per dollar in morning trading, reflecting minimal overnight shifts.

The parallel “blue dollar” rate stood at around 1,455 pesos per dollar, maintaining a narrow 1.1% premium over the official rate—a marked convergence from earlier spreads in the year.

This stability follows a modest weakening on October 30, driven by profit-taking after a post-midterm election rally that strengthened the peso by 4%.

President Javier Milei‘s party secured a stronger-than-expected victory in the midterms, enhancing legislative support for economic reforms and boosting investor confidence.

U.S. Treasury interventions, including a $20 billion currency swap and direct dollar sales estimated at $1.4 billion to $1.7 billion, played a pivotal role in curbing depreciation.

Treasury Secretary Scott Bessent urged private investors to capitalize on this momentum, signaling a transition toward market-led recovery. The U.S. Dollar Index hovered at 99.52, exerting mild pressure on emerging currencies like the peso.

The narrowing gap between official and blue rates indicates improving market health, with reduced speculative demand and capital flight risks.

However, persistent inflation above 100% annually continues to challenge economic stability. Analysts caution that stalled reforms could widen the disparity anew.

Argentina equities pause after election gains

In equities, the S&P Merval Index closed October 30 at 2,787,553, down 0.51%, pausing after a 57.97% monthly gain fueled by election optimism. Trading volumes were subdued, with sentiment buoyed by potential easing of bank reserve requirements to enhance liquidity.

Among top performers: Siderar (TXAR) rose 2.85% to 722.50, Bolsas y Mercados Argentinos (BYMA) gained 2.76% to 279.00, Grupo Financiero Galicia (GGAL) increased 1.46% to 8,005.00, Metrogas (METR) advanced 0.43% to 2,342.00, and Transportadora de Gas del Norte (TGNO4) climbed 0.42% to 4,145.00.

Leading decliners included Edenor (EDN) down 3.47% to 2,284.00, Cresud (CRES) falling 3.10% to 1,750.00, Transportadora de Gas del Sur (TGSU2) dropping 2.98% to 9,120.00, Grupo Supervielle (SUPV) decreasing 2.69% to 3,347.50, and Telecom Argentina (TECO2) declining 2.31% to 3,167.50.

Technical analysis suggests a bullish bias for both the peso and stocks if key supports hold, amid ongoing reforms and regional implications for South American markets.
