* Fed comments dominate as Trump offers no detail on stimulus
* Dollar index hits 7-week high
* Peso up, yuan losses limited

LONDON, March 1 (Reuters) - The dollar hit its highest in seven weeks on Wednesday as signs from two influential Federal Reserve policymakers that interest rates could rise this month overshadowed President Donald Trump's first major policy speech to Congress.
New York Fed President William Dudley, a permanent voter on the U.S. central bank's open market committee and close ally of chair Janet Yellen, said that the case for tightening monetary policy "has become a lot more compelling".
John Williams, President of the San Francisco Fed, said that a rate increase was very much on the table for serious consideration at the March meeting given full employment and accelerating inflation.
That drove the return for holding dollars on the debt market higher, with 10-year Treasury yields last up around 5 basis points at 2.411 percent US10YT=RR .
Money market futures FFH7 FFJ7 were now pricing in almost a 70 percent chance of a rise in official interest rates in March, compared to just over 30 percent on Tuesday.
"The comments from other Fed officials this week have added to this relatively hawkish bias in rate markets and given the dollar some support," said Barclays (LON:BARC) strategist Mitul Kotecha.
Tuesday's expectations that Trump would give details on stimulus plans that drove stellar gains in the dollar in November were largely disappointed.
In a speech that contrasted with harsher rhetoric during his election campaign, Trump said he was open to reforming the U.S. immigration system and pledged massive tax relief for the middle class, but did not expand further. yuan, which has been a target for markets given Trump's previous aggressive talk on trade but which has risen for the past two months as the dollar's rally stalled, was down just 0.2 percent on the day.
The Mexican peso, seen as the most vulnerable to Trump's protectionist policies, also took his speech in stride. It was little changed at 20.066 per dollar MXN=D4 .
"Today was 'good Trump' compared to the aggressive 'bad Trump' shown on Twitter," said Ayako Sera, market strategist at Sumitomo Mitsui Trust Bank.
The greenback was last up 0.7 percent at 113.60 yen JPY= . It gained 0.3 percent against the euro to $1.0544 EUR= , generating a roughly half percent rise in the dollar index, which measures the dollar against a basket of six major peers .DXY .
