NEW YORK/LONDON, Dec 21 (Reuters) - Gold ended higher on Friday after rebounding off its lowest price in nearly four months, but the precious metal notched its steepest weekly decline since June, as uncertainties over the U.S. budget weighed on bullion prices most of this week.
Republican lawmakers in Congress withheld support on Friday for a proposal to avert the so-called U.S. “fiscal cliff”, reinforcing concerns that a budget deal will not be reached before the end of the year to hold off $600 billion in tax hikes and spending cuts.
The dollar soared as it appeared as a better safe-haven to investors than gold after the Republicans’ action.
Prices of gold initially fell along with those of oil on less demand from holders of the euro for those dollar-denominated commodities. Bullion, however, recovered on late buying support to settle slightly higher.
By 4:45 p.m. EST (21 45 GMT ) , the spot price of bullion hovered near $1,656 per ounce. That was up from Thursday’s late trade of $1,647 and the day’s low of $1,635.24, although it was still below the 200-day moving average of $1,663.
In the previous session, gold had plumbed a four-month low of $1,635.09.
On a weekly basis, bullion finished down 2.4 percent in its biggest weekly decline since the week ended June 24.
In futures trading, gold’s most-active February contract in New York settled at $1,660.10, up 0.9 percent on the day and off 2.6 percent on the week.
“Given today’s trade, there’s one constituency in the market at least that seems to think bulls are getting ready to defend gold more aggressively after the free fall earlier in the week,” said Adam Sarhan at Sarhan Capital in New York.
“To me, a sustainable rally in gold can only take place when the market gets back above its 200-day moving average. Barring that, we could technically head to as low as $1,523.”
MARKET PLAYERS “SPOOKED”
Swiss bank UBS appeared to agree, saying gold’s break of the 200-day moving “spooked a lot of market participants”.
“The technical picture doesn’t look great, and neither does sentiment,” UBS said in a note.
Matthew Turner, analyst at Mitsubishi, said it would be difficult to guess the direction in gold as long as the U.S. budget talks remained unresolved.
“Nervousness over the fiscal cliff is possibly keeping some investors on the sidelines, as it is unclear how gold will react to the ongoing fiscal cliff talks,” Turner said.
Gold has reacted both positively and negatively to twists and turns in the budget negotiations. Some analysts say a stalemate in the talks boosts gold’s position as a safe-haven. Others argue that gold has increasingly become a risk asset like any commodity and that a budget deal would give investors in the precious metal clarity on direction.
In Friday’s session, gold initially fell after U.S. House of Representatives Speaker John Boehner failed to unite his Republican lawmakers behind a bid to extract concessions from President Barack Obama.
Despite this week’s sell-off, gold is up about 5 percent for the year. It is also set for a 12th straight year of gains, thanks to rallies in earlier months driven by rock-bottom interest rates, euro zone worries and central banks’ buying of gold.
Among central banks attracted to bullion this year was Iraq, which made its first major move in years to boost gold reserves, joining peers from emerging market economies such as Brazil and Russia.
The price drop in recent months has also spurred buying in physical gold, keeping premiums steady at $1 to $1.10 an ounce above London bullion prices.
Among other precious metals, silver was flat at $29.95 an ounce. It underperformed gold this week to fall nearly 7 percent and is on track for its biggest monthly drop since May.
Spot platinum was down 0.8 percent at $1,533 an ounce, while spot palladium was flat at $677 an ounce. Palladium has been the best performer of the precious metals so far this quarter, up 7 percent.
