Bradesco ADRs Plunge Over 30% on Surprise Lula Re-election in Brazil

American Depositary Receipts (ADRs) of Banco Bradesco SA plunged 31.3% in pre-market trading to $2.794 after the surprise re-election of President Luiz Inácio Lula da Silva in Brazil's presidential runoff on October 25. The unexpected political development triggered a broad sell-off in U.S.-listed Brazilian assets as investors rapidly repriced the country's economic outlook.

Political Shock Upends Market Expectations

The market rout was driven by a sharp reversal of investor positioning. According to a report from Investing.com, market participants had largely anticipated a victory for right-wing senator Flávio Bolsonaro, betting on a platform of fiscal consolidation and policies conducive to lower interest rates.

Lula's victory prompted a rapid unwind of these trades, as investors now grapple with concerns about fiscal discipline under his new administration. The event led to what the source described as one of the most violent single-session repricing events for Brazilian ADRs in recent history.

Widespread Sell-Off Hits Financials, Currency

The decline was not isolated to Bradesco, sweeping across Brazil's entire financial sector. Investors are concerned that elevated government borrowing costs and a weaker Brazilian real could raise funding costs for banks and compress their net interest margins.

The sharp fall in the Brazilian real in overnight currency markets also mechanically reduces the U.S. dollar value of ADRs. The sell-off was specific to Brazil, as major U.S. indices were modestly higher, underscoring the role of country-specific political risk.

Pre-Existing Credit Concerns Amplify Decline

Bradesco's stock was also under pressure from pre-existing concerns about its credit quality. The bank's recent third-quarter 2026 earnings report showed its over-90-day non-performing loan (NPL) ratio had increased to 4.6% from 4.1%.

Furthermore, management had acknowledged that a significant improvement in the NPL trend might not occur until mid-to-late 2027, according to the report. This lingering uncertainty over asset quality left the bank particularly exposed to the negative shift in macroeconomic sentiment following the election.
