Ibovespa Rises 2% as Treasury Yields Ease: How Far Will It Go?

The Ibovespa surged over 2% on Friday, reaching a high of 171,425 points, accumulating a gain of 3,500 points over the previous close. The dollar, on the other hand, fell below R$ 5.17, hitting a low of R$ 5.15 during the morning. The trigger for this movement came from abroad: the easing of U.S. Treasury yields, which had been pressuring emerging markets in recent weeks.

The relief in Treasuries occurred after the U.S. Treasury increased the volume of long-term bond buybacks, a maneuver to improve market liquidity. The immediate result was a drop of more than 10 basis points in the medium and long-term points of the Brazilian futures interest rate curve, creating room for the recovery of risk assets.

But the question that matters to investors is: does this movement have legs, or is it just a breath within a more fragile trend?

What’s Behind the Rise of Ibovespa

The mechanism is relatively simple. When long-term U.S. interest rates fall, the opportunity cost of investing in emerging markets decreases. Money that was allocated in 10 or 30-year Treasuries, offering high returns with U.S. sovereign risk, begins to seek higher premiums in other markets. Brazil, with its discounted assets and appreciated commodities, comes into focus.

The iShares MSCI Brazil ETF (EWZ), traded in New York and considered a thermometer of foreign appetite for Brazilian stocks, was up more than 2% since the opening. This flow of external capital helps explain why practically all stocks in the Ibovespa were trading positively, with only two exceptions among the index components.

Rebecca Nossig, equity strategist at Nomad, described the scenario as one of "meticulous adjustments, where the market calibrates its positions with each new headline from abroad." This reading reinforces something we have been observing in market coverage: the Ibovespa remains more reactive to global factors than to domestic fundamentals.

Blue Chips Act as a Protective Shield

The trio that accounts for half of the theoretical Ibovespa portfolio sustained the rally. Vale rose 2.22%, priced at R$ 75.66, benefiting from the appreciation of metal commodities. Petrobras was up between 0.47% and 0.51%, with Brent crude trading around $94. The banking sector, measured by the Financial Index (IFNC), recorded a rise of 2.59%, driven by Itaú Unibanco, which gained 2.19%.

This concentration in heavyweight stocks acts as a sort of cushion. While Vale, Petrobras, and the major banks support the index, less liquid stocks may perform erratically without significantly impacting the main number. For investors who look only at the Ibovespa as a benchmark, the picture may be more generous than the reality of their individual portfolios.

On the negative side, PetroRecôncavo fell 0.66% and Braskem dropped 0.20%. In the case of the petrochemical company, the situation is more delicate: Citi reiterated a sell recommendation with a target price of R$ 4.50, implying a potential devaluation of over 11%. The company also confirmed that it continues to negotiate with creditors amid CVM inquiries about its financial situation.

Weak Dollar: Trend or Pause?

The DXY index, which measures the strength of the dollar against a basket of six major currencies, fell to the 98-point level. This global weakness of the American currency translated directly into the Brazilian exchange rate, with the dollar trading at R$ 5.16, a decline of more than half a percentage point.

The dynamics of the Brazilian exchange rate have been influenced by two competing vectors. On one hand, the interest rate differential between Brazil and the United States remains attractive, favoring the inflow of resources. On the other hand, as we have analyzed in previous materials, domestic fiscal uncertainties and the electoral cycle that is beginning to heat up add a risk premium to the real.

Investors were awaiting the release of a new Datafolha poll, with expectations of a narrowing in voting intentions between President Lula and Senator Flávio Bolsonaro. Historically, electoral cycles in Brazil increase the volatility of assets and raise the risk premium demanded by the market, especially when the contest appears competitive.

Technical Bounce or Trend Resumption?

The technical analysis team at Itaú BBA issued a warning that deserves attention. According to analysts, the upward movement "appears weak and should be interpreted as a bounce within the main downward trend, which requires caution in allocation and asset selection."

In other words: the 2% rise in a single trading session, no matter how significant it seems, may just be a point correction after recent declines, and not the start of a new upward leg. This reading is consistent with what we discussed about the fiscal scenario and its effects on asset pricing in Brazil.

For investors, the message is one of prudence. The drop in Treasuries eased the pressure on emerging markets, but did not resolve the structural problems weighing on the Ibovespa: fiscal uncertainty, uncertain Selic trajectory, and an electoral scenario that tends to amplify volatility in the coming months.

Days of strong gains amid undefined trends are common and often create a false sense of security. Investors who confuse a bounce with a trend reversal risk positioning themselves at the wrong time. Data shows that the Ibovespa remains trapped between global and domestic forces that have yet to find equilibrium.
