WASHINGTON, April 18 (Reuters) - Japanese Finance Minister Shunichi Suzuki said on Thursday the yen's recent declines likely reflect various factors, not just interest rate differentials.

"Exchange-rate levels aren't determined just by interest rates. Various other factors, such as each country's current account balance, market participants' sentiment, and speculative trade, drive currency moves," Suzuki said at a news conference after attending the Group of 20 (G20) finance leaders' meeting in Washington.
