Asian stocks fell sharply after Wall Street's sharp decline, as investors reacted to President Trump's 10-day extension of Iran nuclear talks deadline. The White House announced the move, giving Tehran until October 15 to finalize a deal or face renewed US military strikes. Traders now assess whether this delay will calm oil markets or create further uncertainty. The 10-day extension directly impacts energy stocks and regional currencies, with major indices in Tokyo and Seoul seeing significant losses. Trump's decision to delay action reflects ongoing diplomatic efforts but raises questions about market stability in the short term.
