The arcabouco against the election.
A fiscal framework straining at the worst moment.

Brazil replaced its rigid spending cap with the arcabouco fiscal, a framework of primary-balance targets and real-spending-growth limits designed to stabilise debt while allowing the government room to invest. The design is reasonable; the arithmetic is brutal. With the Selic at 14.25 percent, Brazil pays one of the highest interest bills in the world relative to GDP, and that cost compounds a gross debt ratio that has climbed toward 80 percent. Even a respected primary target struggles to stabilise debt when nominal interest rates run this far above nominal growth. The framework is straining not because it is badly designed but because the cost of money is punishing.

The framework's test comes at the worst possible moment. Election years generate powerful incentives to loosen - to lift transfers, delay consolidation and prioritise growth over targets - and 2026 is no exception. The market watches every signal on whether the government will meet, miss or redefine its primary target, and whether the next administration of either stripe will respect the framework at all. The interaction with monetary policy is vicious: fiscal slippage raises inflation expectations, which keeps the BCB tight, which raises the interest bill, which worsens the fiscal arithmetic. Fiscal credibility and the high real rate are two ends of the same problem.

The market expresses its fiscal verdict through the steepness of the local curve, the level of the real, and the sovereign risk premium. Long local rates carry a substantial fiscal-risk premium over the policy rate, the real trades with an election discount despite its carry, and any headline suggesting framework slippage moves all three. Brazil's external position is more reassuring - it holds substantial reserves and runs a manageable current-account deficit funded partly by commodity exports - so the fiscal risk is domestic and political rather than an external-solvency story. The sovereign is sub-investment-grade at most agencies but with stable-to-improving momentum that a credible post-election path could extend.

Our base case is muddle-through: the framework is broadly respected, the primary target is approximately met or modestly missed, and the debt ratio grinds higher slowly while the high real rate keeps the doom loop contained but unbroken. The bull case is post-election credibility - a government that commits convincingly to the framework, breaking the loop, enabling BCB cuts and a sovereign re-rating. The bear case is framework abandonment that de-anchors expectations, steepens the curve and pressures the real and the rating. The fiscal outcome and the monetary outcome are, once again, the same outcome viewed from different ends.
