SINGAPORE, June 22 (Reuters) - The dollar eased versus the yen on Thursday as a recent rally tied to bets on another U.S. interest rate hike this year lost steam, while the New Zealand dollar rose after its central bank stopped short of aggressively trying to talk down the currency.
The New Zealand dollar was the big mover during Asian trade, rising 0.4 percent on the day to $0.7248 NZD=D3 , edging back in the direction of a four-month peak of $0.7320 set last week.
The kiwi rose after New Zealand's central bank played down the recent rise in the currency, while it kept interest rates steady at record lows as analysts had widely expected. main takeaways from the statement were pretty much in line with the last statement. They're still optimistic and positive on the medium-term growth outlook," said Peter Dragicevich, G10 FX strategist for Nomura in Singapore.

The U.S. 10-year bond yield is now 209 basis points above its Japanese counterpart, compared to levels around 237 basis points seen in the early part of May.
"Yield differentials should continue to drive dollar/yen direction," Wong said, adding that a pick-up in U.S. inflation data is needed for markets to price in higher U.S. Treasury yields and lift the dollar.
