NEW YORK, Sept 15 (Reuters) - The dollar rose on Friday to cap its second weekly gain against the euro as dealers tweaked positions ahead of a weekend Group of Seven meeting and shrugged off tame U.S. inflation data.
The euro came under fire throughout the day, particularly against the yen as traders sold the currency aggressively in case G7 officials made fresh appeals for exchange rate flexibility in emerging Asian economies.
In April, the G7 called on China and other Asian countries to let their currencies rise, sparking a 2 percent fall in the dollar against the yen, which is often viewed as a market proxy for the tightly controlled Chinese yuan.
Last week, a German official said yen weakness would be discussed at the Singapore G7 meeting.
Despite the rapid ebb and flow of such speculation, dealers were unwilling to push any of the major currencies beyond the confines of their recent ranges.
In fact, data on Friday afternoon showed speculators almost completely wiped out their positions against the dollar in the week to Sept. 12, while extending their bets against the yen to a record.
“In general, people do not want to be long or short or putting any major positions going into the IMF and G7 and, of course, the Fed meeting next week,” said Dustin Reid, senior currency strategist at ABN AMRO in Chicago.
The euro was down nearly 0.5 percent at $1.2660 , above the session low at $1.2629, which was its lowest level since late July. The currency was also off 0.5 percent at 148.86 yen .
The dollar was little changed on the day against the yen at 117.56 yen after earlier testing a five-month high of around 118.15 yen.
The Federal Reserve is not expected to move interest rates from their current rate of 5.25 percent next week, and officials have cited slowing U.S. growth and softer inflation in coming months as grounds for steadier policy.
This would suggest the dollar should decline against major currencies as its perceived yield advantage wanes.
But, so far, the greenback has not obliged, and the euro has failed to break out of a broad $1.2980-$1.2450 range despite signals from the European Central Bank that interest rates are likely to climb in October and possibly again before year end.
Dealers have been paring back their short dollar positions as many in the market felt these had become overstretched.
Indeed, according to Reuters calculations, Friday’s positioning data from the Commodity Futures Trading Commission showed the total value of the net short dollar position plummeted to $4.2 billion from $15.1 billion in the prior week.
Also, there is a risk that the G7 will issue a communique that does not specifically call for a rise in the value of emerging Asian currencies to avoid a repeat of the sharp decline in the value of the dollar after April’s meeting.
The ECB and the Bank of Japan, meanwhile, have moved more slowly in pushing their own rates up
Traders said that is partly why the dollar gained after data showed U.S. core consumer prices, without energy and food costs, rose just 0.2 percent in August, echoing the Fed’s predictions of slower inflation.
The dollar also hit a 4-1/2 month high against the Swiss franc on Friday and rose nearly half a percent against sterling to reach $1.8782.
The U.S. currency also got a boost from data showing a gain in New York area manufacturing in September.
Taken together with the consumer price index, the news is “consistent with a slew of incoming data that tells us that the third-quarter growth has rebounded and inflation has moderated,” said Michael Woolfolk, senior currency strategist at The Bank of New York.
A rise in the University of Michigan’s preliminary reading on U.S. consumer sentiment in September had little effect on currency prices.
