Citi expects Japanese authorities may intervene in the foreign exchange market if the dollar-yen rate rises to around 160, aiming to push it below 155. According to Sina Finance, the bank said potential intervention and higher interest rates are beginning to support the yen, while it sees limited upside for euro-yen and expects the pair may fall to around 170 next year. Citi also warned that if European financial markets become more volatile, that move could happen earlier.
