Toyota Motor Corp. is expected to log a record operating profit for the current business year through March aided by the yen's fall, which boosts export competitiveness, sources said.

The auto giant's full-year operating profit is likely to reach ¥2.40 trillion or ¥2.50 trillion, eclipsing the previous record of ¥2.27 trillion marked in fiscal 2007 before the global financial crisis that erupted in 2008.

The dollar has been moving in the range higher than the company's assumed annual exchange rate average of ¥97. Its operating profit rises ¥40 billion for every ¥1 decline against the dollar.
