Emerging-market stocks and currencies remained under pressure on Tuesday as the stalemate in US-Iran talks pushed crude oil prices back above $86 a barrel. Investors grew cautious amid heightened geopolitical risks, with the diplomatic impasse weighing on sentiment across developing economies. The lack of progress in Washington and Tehran overshadowed other market drivers, causing a broad-based selloff in equity indices from Asia to Latin America. Currency pairs linked to commodity exporters weakened as the surge reignited inflation concerns and prompted central banks to reconsider rate-cut expectations.

Analysts noted that the deadlock, combined with persistent supply worries, could keep energy costs elevated for longer than anticipated. This environment poses a particular challenge for emerging markets that rely on cheap imports and are already grappling with currency depreciation and capital outflows. According to Bloomberg Markets, the situation illustrates how diplomatic delays directly translate into financial market volatility. The $86 threshold serves as a psychological trigger for further downside in risk assets, with participants closely watching any developments in the negotiations for clues on the path of energy prices and broader macroeconomic conditions.
