* But some point to risks of more profit-taking in euro

LONDON, Feb 3 (Reuters) - The euro was steady, hovering not far below a 12-week high on Thursday as the market awaited a European Central Bank meeting and news conference, where hawkish comments could give it a further boost.
The euro could gain even more if Federal Reserve Chairman Ben Bernanke, who is due to speak only a few hours after ECB chief Jean-Claude Trichet, reaffirms the bank's policy is still focussed on boosting growth.
However, some suspect expectations of hawkish ECB rhetoric may have built up too much, leaving room for disappointment and posing downside risks for the single currency.
Market players will be looking for any hints on when euro zone interest rates might rise, given Trichet's recent warnings on the need to tackle inflationary pressures. Accelerating inflation and funding problems for peripheral banks are set to top the agenda at the meeting. [
]"The market is looking for confirmation of a more hawkish Trichet, though the risk/reward is that there is the potential for disappointment," said Lauren Rosborough, currency strategist at Westpac.
The euro dipped 0.1 percent to $1.3790 <EUR=>. It slipped on profit-taking after marking a 12-week high of $1.3862 on Wednesday, though it is more than 7 percent above a four-month trough of $1.2860 hit less than a month ago. Traders cited talk of an options barrier at $1.3900.
Rosborough said further gains could leave the euro on track to test $1.40, but falls due to Trichet disappointment, or from any safe-haven dollar buying due to concerns about unrest in Egypt, could push it towards last week's low around $1.3530.
The ECB announces its policy decision at 1245 GMT, with a news conference at 1330 GMT. Market players were also wary ahead of auctions of Spanish and French debt.
"I think the market expects the ECB to be hawkish. But as the euro has already risen quite a lot, market players are cautious about chasing it higher," said Tsutomo Soma, a manager of foreign bonds at Okasan Securities in Tokyo.
Similar risk also exists for the speech from the Fed chief, due at 1730 GMT, if he turns out to be less dovish than many market players have hoped.
Many market players do not expect the speeches from the world's two most influential central banks to change the perception that the ECB will be way ahead in raising rates.
The dollar index <.DXY> was steady at 77.147, near a 12-week low of 76.881.
RATE FOCUS
Growing expectations that high inflation could force the Bank of England to raise interest rates sooner rather than later pushed sterling to a three-month high versus the dollar of $1.6245 <GBP=D4>.
The Australian dollar <AUD=D4> also performed well after strong Australian trade data [
], rising 0.5 percent to $1.0133, though the New Zealand dollar <NZD=D4> fell 0.6 percent after weak New Zealand jobs numbers. [ ]While interest rate differentials are seen playing a big role in currency transactions, one currency pair that has seen a breakdown in correlation with yields is the dollar/yen, which was steady at 81.78 yen <JPY=>.
The yield on U.S. two-year notes, which had strong correlation with dollar/yen moves last year, has almost completely lost its link to dollar/yen in the past month.
"The market seems to no longer be looking at yield gaps. What's we are seeing is that investor buying of bonds is dwindling. Instead, their money seems to be heading for commodities," said Katsunori Kitakura, chief dealer at Chuo Mitsui Bank in Tokyo.
