Treasury Secretary-designate Timothy Geithner said on Thursday that he supported a strong dollar.
"A strong dollar is in America's national interest," Geithner said in written answers to questions from members of the Senate Finance Committee as part of his confirmation process. The answers were released on Thursday.
He also promoted President Barack Obama's stimulus plans and financial bailout spending as essential to long-term economic health.
"These are the actions that should allow us to maintain confidence in the long-term strength of the United States economy and the stability of the US financial system," said Geithner, who has been President of the New York Federal Reserve Bank.
In his testimony at the Senate Finance Committee on Wednesday, Geithner apologized for late payment of over 34,000 dollars in income taxes earlier the decade.
"I have paid what I owed," Geithner said at the hearing. "I apologize to the committee for putting you in the position of having to spend so much time on these issues."
Geithner paid back taxes and interest for 2003 and 2004 after an Internal Revenue Service audit. While he made the same tax error in 2001 and 2002, he did not pay back taxes for those years until after President Obama expressed interest in nominating him.
Also in his testimony, Geithner called for a "fundamental reform" of the government's 700-billion-dollar bailout plan, saying it favoured big financial institutions over small businesses and struggling families.
"Many people believe the programme has allowed too much upside for financial institutions, while doing too little for small business owners, families who are struggling to keep their jobs and make ends meet, and innocent homeowners," he said.
"We have to fundamentally reform this programme to ensure that there is enough credit available to support recovery," he added.
He also vowed to take swift actions to get credit flowing again.
"Our test is to act with the strength, speed and care necessary to get our economy back on track, and restore America's faith in our economic future," he said.
The committee scheduled a vote on Geithner's nomination on Thursday, which could put the nominee on track to win the needed backing of the full Senate by the end of the week.
