Why MercadoLibre (MELI) shares are plunging today

What happened?

Shares of latin American e-commerce and fintech company MercadoLibre (NASDAQ:MELI) fell 11.3% in the morning session after Brazilian President Luiz Inácio Lula da Silva secured an unexpected runoff victory over conservative challenger Flávio Bolsonaro, reversing weeks of rallies driven by expectations of a business-friendly administration.

Lula secured 51.8% of valid votes against Bolsonaro’s 48.2%, based on official electoral tallies cited by TipRanks. Investors had favored Bolsonaro on expectations that his platform of government spending restraint and corporate tax reductions would rein in public debt and permit the central bank to cut borrowing costs, Investing.com reported.Brazil is MercadoLibre’s largest geographic market, generating $5.53 billion, or 54.4%, of the company’s $10.17 billion in total net revenues and financial income in the second quarter, according to its Form 10-Q quarterly filing with the U.S. Securities and Exchange Commission.

Because MercadoLibre reports in U.S. dollars, a depreciating real (Brazilian real) directly reduces the translated value of its Brazilian marketplace and payments income, while elevated domestic interest rates increase funding costs and bad-debt risks across its Mercado Pago credit portfolio.
