Brazil’s markets like the tie that should worry them

Brazilian stocks rose for eleven straight sessions into early September and the currency firmed to around five reais to the dollar. The occasion was not a vote of confidence in the president. It was a poll showing the president boxed in. President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro, the son of the imprisoned former president, are now statistically tied: an AtlasIntel survey run for Bloomberg and released on September 10 gave each 46% in a simulated runoff, while a Quaest poll only days earlier also had them level, at 41% apiece. A first round is scheduled for October 4, with a likely runoff three weeks later.

The cheer that followed is worth understanding, because it is not what it looks like. Investors are not applauding the younger Bolsonaro, a man who was once treated as a market shock in his own right: when his father signalled in late 2025 that his son would carry the party’s flag, the real dropped almost 2.3% in a day, its worst move in months. What the markets are applauding is the destruction of an assumption — that Lula’s re-election was all but certain. And that assumption, as it turned out, was carrying a heavy price.

For most of the year Brazilian assets priced a second Lula term as the base case. With the Workers’ Party triumphant came particular fears: state-led spending, talk of capital controls from a campaign coordinator, a six-day working week to be gutted for politics, and a president who has shrugged off deficits. Investors’ worry was not Lula the man but Lula unchecked — a government with a mandate and no opposition strong enough to tug it towards the centre. A coin flip changes the appeal of that trade. A genuine contest, the reasoning goes, forces either candidate to moderate, hands whichever wins a more fragmented congress, and opens the door to a change of government and, with it, faster interest-rate relief. “The race is tighter than it seemed a month ago,” remarked the chief investment officer of SulAmérica, explaining why Brazilian assets beat global peers on September 8.

Hence the apparent paradox in the numbers. The Ibovespa closed up 3% on September 2, its best day in months, led by state-sensitive banks; it climbed again a week later. Short-term rates fell, January-2031 futures easing to 13.9%. The market is not backing a candidate. It is pricing the absence of a foregone conclusion, and finding that less frightening than the conclusion itself.

The institution that made it close

The trouble is where that close race came from. It is not the product of a compelling rival or a buoyant economy — on the contrary, Lula’s approval has fallen to roughly 44%, its lowest since January 2024, amid a cooling economy and allegations touching his son. It is largely the product of a Brazilian institution breaking in public.

Brazil’s Supreme Court has turned on itself, weeks before it will be asked to certify an election. Justice Alexandre de Moraes, who led the case that jailed the elder Bolsonaro for plotting a coup, and Justice André Mendonça, appointed by him, are now effectively investigating each other. The trigger was the collapse of Banco Master, a failed lender at the centre of a sprawling fraud probe: Mendonça unsealed phone records suggesting a closer relationship than was known between Moraes and the bank’s former owner, Daniel Vorcaro. The Senate held 109 impeachment requests against the Court’s ten sitting justices as of September 1; eleven of the Federal Police’s fifteen directors have walked out. The younger Bolsonaro is milking the feud — “anyone who votes for Lula is voting for Alexandre de Moraes” has become his stump line — and the right is treating the Court, once its own adversary, as living proof of elite corruption.

Set the politics aside and the economics of this is uncomfortable. The market’s relief is buying a probability shift, not an improvement in the fundamentals the election will inherit. Whoever governs, the fiscal arithmetic binds. The Selic rate sits at 14%, cut only recently from a near-two-decade high. The primary budget is roughly in balance or slightly in deficit, but the debt is climbing: the IMF projects gross public debt reaching 99% of GDP by 2030, up from 62% in 2010. And the Treasury’s financing has quietly become a warning. Investors, shunning long-dated Brazilian paper, are being handed an ever-larger share of floating-rate bonds tied to the Selic; such instruments reached 49.32% of the debt stock in June, near the ceiling of the government’s own target.

This is the mechanism the rally does not touch. A close election may trim a political premium, but it does nothing for an interest bill that rises with the very policy rate markets are hoping to see cut, and nothing for a debt path the IMF calls unsustainable. The same court crisis that helped make the race competitive — and thus lifted asset prices — is itself a mark against the institutional credibility on which emerging-market risk premia ultimately rest.

What the foreign money is saying

The most instructive signal may be who is not buying the relief. The main Brazil exchange-traded fund listed in New York, EWZ, has shed roughly $1.6bn of assets over three months and about $860m in the last month, even as the local Ibovespa rallied. That divergence is the tell: the cheer is largely a domestic, positioning-led repricing — local institutions unwinding the bearishness they had built against a Lula certainty — rather than a wave of new foreign conviction. Global allocators, whose capital Brazil needs to fund its borrowing, are conspicuous in their absence.

What should a retail investor take from this? Not a candidate call. The lesson is structural, and it concerns how markets treat certainty about powerful incumbents. The bond between Lula’s presumed inevitability and cheap Brazilian assets was the real investment story of 2026’s first half, and it has now been quietly unwound. But the alternative hypothesis — that a knife-edge race is a clean referendum that will end in responsible government — is being priced with a credulity the fiscal and institutional evidence does not support. A market that rallies on a closer race while its central institution tears itself apart, its debt lengthens in the riskiest way, and its foreign investors walk away is not pricing risk off the table. It is pricing some of it in the wrong drawer.

The run-up to October 4 will bring more polls, more fever, more swings. Investors who remember that the real object of transaction — Brazilian fiscal and institutional credibility — barely moved while the index celebrated will be better placed than those who mistake the relief rally for the story itself.
