LONDON, Feb 25 (Reuters) - The yen trimmed losses against other major currencies on Wednesday as traders took profits from a recent bout of yen-selling, while lacklustre economic data supported the dollar.
The dollar was also boosted after the head of sovereign ratings at Standard & Poor's said he expected more sovereign ratings downgrades than upgrades this year compared with a year ago [

Latest data showing a sharp drop in Japanese exports prompted the euro to a fresh seven-week high of 125.17 yen <EURJPY=> but the pair was unable to sustain gains.
By 1148 GMT, the euro was down 0.6 percent at 123.40 yen. The yen also recovered against other pairs, with sterling falling more than one percent on the day to 138.56 yen after jumping to 141.81 -- its highest this year <GBPJPY=R>.
The dollar was down 0.2 percent at 96.56 yen <JPY=>.
While the yen-selling momentum lost some steam, the Japanese currency remains vulnerable, analysts said.
"The yen continues to weaken and it will come under increasing pressure," said Ian Stannard, senior currency strategist at BNP Paribas.
Meanwhile, the dollar was supported as a grim economic outlook remains intact. The dollar was up 0.6 percent against a basket of currencies at 87.294 <.DXY>

But analysts said the rally in riskier assets, which also bolstered currencies such as sterling and the Australian dollar, was looking shaky, although European shares were still up 0.4 percent by midday trade <

"The focus can easily switch back to how bad the situation with the banking sector and the global economy is, and this tends to lead to dollar strength," he said.
U.S. S&P stock futures were down 0.6 percent <SPc1>, indicating a lower open on Wall Street.
Data on Wednesday showed Germany's economy contracted by a record 2.1 percent in the fourth quarter, dragged down by foreign trade. See [
