Lula's Congressional Support Collapse Raises Fiscal Alarm, Forces Unprecedented STF Maneuver

President Luiz Inácio Lula da Silva’s political support in the National Congress has collapsed despite the release of a record R$33.89 billion in parliamentary amendments in the first half of the year, raising immediate concerns over Brazil’s fiscal stability and the future trajectory of the Brazilian real (USD BRL). Data shows the President's support for priority bills has dropped sharply year-over-year, falling from 75% to 38.5% in the Senate and from 58% to 38.1% in the Chamber of Deputies. The failure of record executive branch spending to secure a legislative majority creates an immediate threat that fiscally irresponsible bills—known locally as pautas-bomba, or "spending-bombs"—will be approved, prompting the administration to consider the unprecedented step of asking the Supreme Federal Court (STF) to block the legislation.

This legislative gridlock and the rising cost of governability are the primary mechanism weighing on Brazilian assets. Investors have grown increasingly concerned that the administration’s focus on increasing spending combined with its inability to stop new, unfunded liabilities will lead to a sustained fiscal imbalance, which historically forces the Central Bank to maintain its high benchmark Selic interest rate. Fiscal policy, not monetary policy, is currently the market's greatest fear, with the Finance Ministry calculating the potential impact of some recent spending bills at over R$800 billion over a decade, and the broader threat up to R$2 trillion. The need to resort to the judiciary (STF) to enforce fiscal responsibility on the legislature signals a deep institutional failure that directly impacts the risk premium on Brazilian debt.

The reaction has been clear across the assets: the Ibovespa (IBOV), which tracks the Brazil stock market and its proxy ETF (EWZ), has faced sustained downward pressure on the uncertainty. Likewise, government bonds have seen yields rise as investor demand for a higher premium for carrying Brazilian sovereign risk increases. Markets consistently price in political and fiscal risk through currency depreciation, which is why the Real (USD BRL) remains under pressure as investors fret over the government's willingness and ability to meet its primary surplus targets. This negative feedback loop—where fiscal weakness requires monetary tightening—is proving difficult to break.

The next inflection point for investors will be the administration's formal move to take the pautas-bomba to the STF. The court has a prior understanding that proposals creating new mandatory expenditures must include a revenue source, giving the government a legal argument to challenge the fiscally damaging bills. A successful judicial intervention would temporarily halt the bleed on public accounts and stabilize market sentiment, but a failure would remove the last line of defense against the spending bills, forcing an immediate re-evaluation of the country's sovereign risk and its fiscal future.
