Summary

Merval Argentina today reflects Friday’s 1.44% drop to 2,707,868.63, breaking the 2,750K floor that held twice in May. Trigger: Warsh Fed and US April CPI 3.8% lifted the 10Y to 4.55%, hitting the highest-multiple market in LatAm. The index closed below the 200-DMA at 2,701,583.

The Big Three

1.
Merval closed Friday at 2,707,868.63 (−1.44%, −39,441 points), breaking the 2,749,913 floor that held twice in May. Trigger: Warsh Fed handover and US April CPI 3.8% YoY (highest since May 2023). The 10Y jumped 9bp to 4.55%. CME FedWatch repriced 2026 from a 48% June cut to a 45% hike probability.
2.
Argentina runs the highest forward P/E in LatAm at 19.8x (vs Ibovespa 13.4x, BMV 15.9x). When US real yields blow out, the steepest re-rating hits the richest book first. The Warsh shock landed on a Merval already digesting an April CPI that printed above the 3% threshold the bulls needed.
3.
RSI fast 38.88, slow 44.22 — deeper oversold than May 6 and May 11 floor tests. MACD histogram −14,628, still bearish but narrowing. Friday’s close sits 13.5 points below the 200-DMA at 2,701,583, the line defining the post-midterm uptrend.

03 Why It Sold Off

External Trigger: Warsh Fed and the highest-multiple problem

Kevin Warsh took the Fed Chair Friday; markets read him hawkish. April CPI 3.8% Wednesday and a PPI spike framed the handover. The 10Y jumped 9bp to 4.55%. CME FedWatch repriced June cut odds from 48% to under 8%; 2026 hike probability from 1% to 45%. Argentina at 19.8x forward P/E took the steepest re-rating in LatAm.

Local Overhang: CPI binary, reform-premium fatigue

April INDEC CPI on May 14 was the local binary. A sub-3% print would have revalidated disinflation and unlocked the 2,895K cloud top; the print came in too high and confirmed the March 3.4% spike was not seasonal. BCRA reserves have climbed but country risk is still anchored near 500bps — the line for private market access remains contested. The 2026 maturity wall (US$19B+) still requires either a print breakthrough or a swap drawdown.

Key Facts

The 2,749,913 floor that held twice in May broke Friday — once is a test, twice is support, three times is regime change. The Merval enters this week below the 200-DMA. YPF and Galicia, the index heavyweights, took the brunt: financials suffer when US yields rise and tighten the Fed-BCRA differential; energy names ran into a Brent fade.

The contrarian read sits in momentum. RSI 38.88 is deeper oversold than May 6 (which produced a 4.42% reversal) or May 11. MACD histogram is narrowing despite price falling — classic positive divergence. The soybean inflow window and US$20B swap remain backstops. The level matters more than the entry: below 2,701,583 invalidates the structural uptrend.

05 Technical Snapshot

Argentina Merval S&P BYMA daily chart May 15 2026 close 2707868 Warsh Fed CPI shock RSI 38 oversold MACD bearish 200-DMA 2701583 pierced 2750K floor broken Milei midterm

S&P Merval daily, BYMA. TradingView · May 18, 2026 06:15 UTC

Merval closed Friday at 2,707,869, below the 200-DMA (2,701,583) on a daily-close basis after the session low pierced to 2,698,659. The 50-DMA at 2,784,852 and Kijun at 2,795,565 sit ~3% overhead. Lower Bollinger 2,613,746 is the next floor, 3.5% below spot. MACD histogram −14,628, line −18,708 vs signal −33,336 — bearish but narrowing. RSI fast 38.88, slow 44.22 — deeper oversold than the May 6 and May 11 floor tests, leaves room for a mechanical bounce.

Resistance: 2,749,913 (broken floor) → 2,784,852 (50-DMA) → 2,795,565 (Kijun)
Support: 2,701,583 (200-DMA) → 2,698,659 (Friday low) → 2,613,746 (lower BB)
Invalidation: A daily close below 2,613,746 breaks the post-midterm uptrend and opens 2,500,000.

06 Forward Look

This week · US yields
10Y at 4.55% is the binary. A push to 4.70% sends Merval to 2,613,746; a fade below 4.45% reclaims 2,749,913.
May 22 · Country risk watch
A sustained break above 500bps signals lost market-access window; a move below unlocks refinancing of the US$19B maturity wall.
End May · Soybean inflows
Peak harvest dollars supply BCRA reserve buying. Late-May is the tail of the window before flows fade through June.
June 13 · IMF reserve target
US$4.4B accumulation deadline. A miss reopens the swap-line drawdown question; a clean hit anchors the disinflation glide path.

07 Questions & Answers

Why did the Merval fall on Friday May 15 2026?
Compound trigger. US April CPI hit 3.8% YoY, the 10Y jumped 9bp to 4.55%, and Warsh took the Fed Chair. CME FedWatch repriced from a 48% June cut to under 8%. April INDEC CPI came in above the 3% bulls needed. Argentina’s 19.8x forward P/E is LatAm’s highest, so the re-rating hit hardest.
Is the Milei reform premium broken?
Not yet. The 200-DMA at 2,701,583 was pierced intraday but the daily close held within 1% of it. Country risk near 500bps still sits at the private-market-access threshold. Fiscal surplus, BCRA reserve build, and US$20B swap are intact. The premium is being tested, not broken.
What unlocks a Merval bounce from here?
Three triggers: (1) a fade in the US 10Y below 4.45%, the simplest relief; (2) a soft May CPI in June revives disinflation; (3) country risk sustained below 500bps. RSI 38.88 says the level is right; only the catalyst is missing.

Key Facts

Friday’s 1.44% drop broke the 2,749,913 floor and closed 13.5 points below the 200-DMA. External trigger — Warsh Fed, CPI 3.8%, 10Y at one-year high — hit LatAm’s highest-multiple market hardest. The Milei reform premium is tested at its structural support. RSI 38.88 sits deeper oversold than the May 6/11 lows.

Key level: 2,701,583 (200-DMA). Above and the structural uptrend holds; below and the Bolling at 2,613,746 becomes magnet.
