SINGAPORE/LONDON (Reuters) -The yen dropped on Wednesday after an influential Bank of Japan official played down the chances of a near-term rate hike, soothing investors' concerns that a further jump in the Japanese currency could again rock global markets.

The yen fell around 2.5% to a session low of 147.94 per dollar following the comments from BOJ Deputy Governor Shinichi Uchida. The dollar was last up 1.7% at 146.79 yen.

"As we are seeing sharp volatility in domestic and overseas financial markets, it's necessary to maintain current levels of monetary easing for the time being," Uchida said.

His remarks, which contrasted with Governor Kazuo Ueda's hawkish comments made last week when the BOJ unexpectedly raised interest rates, sent Japanese stocks higher, leaving them effectively flat for the week.

The BOJ's hike last week, along with intervention from Tokyo in early July, led investors to bail out of once-popular carry trades in which traders borrow the yen at low rates to invest in assets that offer higher returns.

The carry unwind has combined with weak U.S. jobs data and fears about an artificial intelligence bubble to send global stocks tumbling this week, started by a 12% crash in Japanese equities on Monday.

"I think it's become increasingly clear that the BOJ hawkish turn last week could be a policy error," said Alvin Tan, head of Asia FX strategy at RBC Capital Markets. "Japan's economy is actually in poor shape, especially domestic demand."

The U.S. dollar index, which measures the currency against six rivals, rose 0.15% to 103.13, inching further away from the seven-month low of 102.15 it touched on Monday.

Rong Ren Goh, a portfolio manager in the fixed income team at Eastspring Investments, said that "Uchida has saved the carry trade - for now".

"Japan policy is one of the important moving parts of the overall risk structure in the market. The other important ones would be U.S. economic data, which in turn informs Fed policy trajectory."

The yen's decline was broad based, with the Mexican peso, New Zealand dollar and Australian dollar - all carry trade candidates - surging against the currency.

RATE CUT WAGERS

The euro eased 0.1% to $1.0923, down from an eight-month high of $1.101 hit on Monday as the dollar dropped. Sterling was 0.1% higher at $1.2704.

Traders ramped up their bets on Federal Reserve rate cuts on Monday following an unexpected jump in the unemployment rate on Friday, at one point pricing in more than 125 basis points of reductions this year.

Those bets have gradually come down, and traders on Wednesday were expecting 100 bps of easing this year and a 62% chance of a 50 bp cut in September, having priced it as a near certainty on Monday.

In other currencies, the Australian dollar was 0.64% higher at $0.6561, a day after the central bank ruled out the possibility of an interest rate cut this year, saying core inflation is expected to come down only slowly.

The Aussie has struggled in recent days, sinking to eight-month lows on Monday in the wake of the global market meltdown but perked up on the day following BOJ comments.

Mark Matthews, head of research for Asia at Julius Baer, said there is no real need for the BOJ to continue raising interest rates.

"After the dust settles, the very wide interest rate differential between Japan and other countries will once again become the primary determination of the yen's valuation versus other currencies."

The New Zealand dollar was up 1.11% at $0.6018 following strong jobs data.
