LONDON, Jan 29 (Reuters) - World shares fell on Thursday, while the low-yielding dollar and yen rose as hopes for the approval of a $825 billion U.S. stimulus package failed to galvanise European investors.
European shares faltered after gains in U.S. and Asian stocks overnight, snapping a three-day winning streak, dragged down by the banking and commodity sectors.
Government bonds slid, taking U.S. benchmark yields to a six-week peak after the Federal Reserve shied away for now from buying Treasuries as part of its aggressive policy easing to relieve credit market strains.
It stood pat on interest rates -- keeping borrowing costs at between 0-0.25 percent and said they could stay unusually low for some time.
President Barack Obama's $825 billion stimulus package cleared its first congressional hurdle in Congress [
] but analysts said the package still had a potentially bumpy road ahead."The package is an encouraging sign, but in itself it does not solve anything," said Justin Urquhart Stewart, director at Seven Investment Management.
