Sept 22 (Reuters) - Gold fell on Tuesday as the dollar
climbed to its highest in over a month, while investors remained
doubtful over additional stimulus measures to aid the
coronavirus-hit economy ahead of speeches from Federal Reserve
officials this week.
Spot gold XAU= fell 0.4% to $1,904.21 per ounce by 1151
GMT, after a steep sell-off dragged it down to its lowest level
since Aug. 12, at $1,882.70 on Monday.
U.S. gold futures GCv1 rose 0.1% to $1,911.60 per ounce.
The dollar .DXY , also considered as a safe-haven, notched
a six-week high against a basket of other major currencies
earlier in the session, dimming the appeal of bullion for other
currency holders. USD/
"Gold could be well below yesterday's lows depending on how
deep the equity sell-off goes. It's just a function of how
panicked investors are," Bank of China International analyst
Xiao Fu said, adding the increased risk-aversion could support
the dollar and weigh on gold.
U.S. President Donald Trump's bid to quickly fill the U.S.
Supreme Court vacancy left by the death of Justice Ruth Bader
Ginsburg left investors fretting over the chances of more fiscal
stimulus before the election. Focus now shifts to Federal Reserve Chair Jerome Powell's
testimony before lawmakers, addressing questions about the raft
of emergency measures the central bank has taken to cushion the
blow to the economy from the pandemic. Governments are unlikely to roll out stimulus at a similar
scale seen when the coronavirus first emerged, even if cases
soar as they have already used much of the ammunition, Bank of
China International's Fu said.
On the technical side, spot gold may retest support at
$1,886 per ounce, a break below which could cause a fall to
$1,855, said Reuters technical analyst Wang Tao. TECH/C
Elsewhere, silver XAG= fell 2.2% to $24.19 per ounce,
platinum XPT= gained 0.3% to $883.85 and palladium XPD= fell
0.2% to $2,269.81.
