NEW YORK, Aug 30 (Reuters) - The yen rose broadly on Monday after the Bank of Japan's decision to expand a fund supply tool disappointed investors who had looked for more aggressive measures to curb the yen's strength.
The dollar fell below 85 yen and the euro lost about 1 percent against the Japanese currency after the BOJ beefed up the supply of fixed-rate loans to banks to 30 trillion yen ($351 billion) from 20 trillion yen.
Investors saw the central bank's moves as a symbolic gesture that will do little to halt the currency's climb, putting the onus on the Japanese government to act if the yen continues to rally. [
]"An increase in the program by 10 trillion yen really wasn't what the market was looking for," said Andrew Busch, currency strategist at BMO Capital Markets in Chicago. "It really leaves one to believe that their policy choices are limited as far as the currency goes."
In early New York trading, the dollar fell 0.5 percent to 84.68 yen <JPY=>, down from the day's high above 85.90 yen hit before the BOJ announced its policy decision. The dollar had earlier hit a session low of 84.56 yen, according to Reuters data, not far from its 15-year low of 83.58 yen set on electronic trading platform EBS last week.
Adding to strength in the yen were comments from Bank of Japan Governor Masaaki Shirakawa, who said after meeting Prime Minister Naoto Kan that Kan had not made any requests on the central bank's monetary policy. Shirakawa refused to comment on recent currency moves.
Earlier in the day, Shirakawa said policy steps will not be bound by moves in the yen and stocks and that the rise in the yen was down to investor aversion to risk. [
]The BOJ's move and the official comments encouraged investors to add to long yen positions as the comments were seen as an indication that FX intervention by Japan was not imminent.
"People are once again putting on short dollar/yen positions, having reduced their long exposure ahead of the meeting," said Niels Christensen, currency strategist at Nordea in Copenhagen.
A trader in London said that stop-loss orders to sell the dollar under 84.90 yen helped accelerate the pair's slide.
LONG YEN POSITIONS INCREASE
The euro <EURJPY=R> fell roughly 1 percent to around 107.65 yen. Against the dollar, the euro lost 0.4 percent to $1.2707 <EUR=>.
Analysts expect the yen to rise further against the dollar if expectations mount that the U.S. Federal Reserve will act to spur growth down the road, moving more aggressively than the BOJ.
Fed Chairman Ben Bernanke said on Friday the economic recovery has weakened more than expected and the Fed stands ready to act if needed to spur slowing growth. [
]Data from the Commodity Futures Trading Commission showed investors increased long positions in the yen and the Swiss franc in the week to Aug. 24 as worries about a slowing global economy encouraged investors to seek perceived safe-haven currencies. [
]Japanese Prime Minister Kan said on Monday that ministers would take economic steps using 920 billion yen ($10.8 billion) in reserves from this fiscal year's budget. See [
]"Japan is facing a rise in the yen, and there are concerns about a slowdown in overseas economies," Kan told a meeting of relevant ministers on the economic measures.
Aside from the yen, currency movements were limited in European trade, with London markets closed for a holiday.
The dollar showed little reaction to U.S. data showing consumer spending rose at the strongest pace in four months in July. [
