Asian currencies weakened against the dollar as investors grew concerned about the potential for a prolonged Middle East conflict. The dollar's strength came as traders sought safe-haven assets amid rising geopolitical tensions. Currency markets across Asia saw broad declines, with traders reacting to developments that could extend instability in the region.

Market participants cited the Middle East conflict as the primary driver behind the currency movements. The uncertainty surrounding the duration and escalation of the conflict has created volatility in emerging market currencies. Investors are particularly wary of how sustained tensions might affect global energy prices and trade flows.

Regional central banks are closely monitoring the situation as currency depreciation could impact inflation and economic growth. The dollar's gains against Asian currencies reflect a broader flight to safety in global markets. Traders expect continued volatility until there is more clarity on the geopolitical situation and its potential economic ramifications.
