NEW YORK The yen fell to a two-year low against the dollar on Wednesday as Japan's new prime minister called for weakening the currency to stimulate inflation, while U.S. stocks slipped, led by declines in retailers' shares.
Sales growth at U.S. retailers was projected to have fallen short of expectations during the holiday shopping season, according to preliminary estimates from firms that track retail spending.
The S&P 500 lost 0.5 percent, with consumer discretionary stocks among the hardest-hit. The Morgan Stanley Retail index .MVR dropped 1.7 percent.
U.S. shares were also pressured as it appeared Congress will not negotiate a deal before January 1 to avoid the "fiscal cliff," a series of spending cuts and tax hikes totaling $600 billion that would slow the U.S. economy sharply unless lawmakers take action.
There was concern that potential tax hikes cut into U.S. holiday spending.
"With the 'fiscal cliff' hanging over our heads, it was hard to convince people to shop, and now it's hard to convince investors that there's any reason to buy going into year-end," said Rick Fier, director of trading at Conifer Securities in New York.
President Barack Obama was to return to Washington on Thursday, earlier than planned, from his Hawaiian holiday to resume talks.
A series of big decisions will wait until early 2013, when tax rates are scheduled to rise for most Americans. Economists warn that the world's largest economy could fall into recession as a result unless action - even retroactive - is taken to cushion the blow of higher rates and reduced spending that has helped bolster a weak economy.
Reflecting some of this uncertainty, the CBOE Volatility Index .VIX, Wall Street's favored measure of anxiety, rose to 19.48, its highest close since late July. The action suggests some concern as the fiscal cliff deadline approaches.
The Dow Jones industrial average .DJI fell 24.49 points, or 0.19 percent, to end unofficially at 13,114.59. The Standard & Poor's 500 Index .SPX .INX was down 6.83 points, or 0.48 percent, to finish unofficially at 1,419.85. The Nasdaq Composite Index .IXIC was down 22.44 points, or 0.74 percent, to close unofficially at 2,990.16.
U.S. stocks have held in a tight range, recovering losses sustained just after the U.S. election in November. The S&P 500 is still up about 13 percent on the year.
The dollar rose as high as 85.74 yen on trading platform EBS, the highest since September 2010, following the swearing-in of Shinzo Abe as premier and was last at 85.64. The euro rose as high as 113.40 yen, a 16-month high, and was last up 1.3 percent to 113.22. The euro was at $1.3224 against the dollar, up 0.3 percent.
Abe is calling for a mix of aggressive monetary policy easing and big fiscal spending to beat deflation and weaken the yen. He is pressuring the Bank of Japan to adopt a 2 percent inflation target that would auger for a weaker currency, threatening changes at the central bank if his wishes are not met.
"The election of Abe has had a galvanizing effect on the dollar/yen exchange rate and he has been able to accomplish more in two months of jawboning than the BoJ has... over the past several years," said Boris Schlossberg, managing director of FX strategy at BK Asset Management in New York.
Many markets remained closed following Christmas. European exchanges were largely shuttered, and Hong Kong and Australia were also closed. The MSCI All-World Index .MIWD00000PUS was down 0.2 percent on Wednesday.
U.S. single-family home prices rose in October for the ninth month in a row. The S&P/Case Shiller composite index of 20 metropolitan areas gained 0.7 percent in October on a seasonally adjusted basis, stronger than the 0.5 percent rise forecast by economists polled by Reuters.
Ten-year U.S. Treasury notes rose 6/32 of a point in price to yield 1.756 percent. <US/>
Brent crude climbed above $110 per barrel on Wednesday, hitting a two-month high, with investors hoping for a last-minute deal to avoid a U.S. fiscal crisis. U.S. crude futures settled at $90.98, up $2.37, or 2.7 percent. <O/R>
The weaker yen has bolstered hopes for better earnings from Japanese companies and underpinned the Nikkei, which has gained about 18 percent since mid-November, when the election was scheduled. The yen has lost nearly 8 percent against the dollar in the same period.
The Nikkei .N225 closed at a nine-month high on Wednesday, with a 1.5 percent gain. .T
Minutes of the BOJ's policy-setting meeting in November, released on Wednesday, showed that some board members said the central bank must act decisively, without ruling out any policy options, if the outlook for the economy and prices worsens further.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was little changed. Shanghai shares .SSEC were flat, but stayed in positive territory on the year after a 2.5 percent jump on Tuesday erased 2012 losses. It is set for its first annual gain in three years.
