PRECIOUS-Gold inches up as focus shifts to Jackson Hole conference

* Investors await Jackson Hole speeches by Yellen, Draghi

* Spot gold may break support at $1,282/oz - technicals

* Dollar eases

(Updates throughout, changes dateline from BENGALURU) JOHANNESBURG, Aug 23 (Reuters) - Gold prices edged up on Wednesday, supported by jitters over political uncertainty in the United States ahead of a major central banking conference this week.

Spot gold was up 0.2 percent to $1,286.77 an ounce at

0926 GMT, after shedding 0.5 percent in the previous session.

U.S. gold futures were unchanged at $1,292 per ounce.

"Gold's kind of hanging in there before this Jackson Hole meeting. It is in a wait-and-see mode but we should have a better idea of direction by the end of this week," said Fawad Razaqzada, a technical analyst at FOREX.com. "There can be an argument made for a bearish view on gold as this stage. If the dollar were to come back due to short covering and given the rally in U.S. stocks we saw yesterday, the buck-denominated and safe haven metal could fall out of favor." Markets are turning their focus to a meeting of central bankers in Jackson Hole, Wyoming, later in the week where Federal Reserve Chair Janet Yellen and European Central Bank chief Mario Draghi are set to deliver speeches on the outlook for monetary policy and interest rates. Gold is highly sensitive to rising U.S. interest rates, as these increase the opportunity cost of holding non-yielding bullion, while boosting the dollar, in which it is priced. "Most of the people are now looking for hints from the Jackson Hole meeting between the central bankers," said Mark To, head of research at Hong Kong's Wing Fung Financial Group. "The most important thing is economic fundamentals ... central banks are going to have tightening measures in monetary policies to have normalization. So I don't have much higher upward momentum for prices," To said. The dollar inched lower after U.S. President Donald Trump raised the prospect of a government shutdown as he tries to force through his plans to build the wall along the border with Mexico. Gold usually fairs well in times of geopolitical uncertainty, while stocks and the dollar generally retreat. Draghi is also due to give a speech in Germany later in the day. Adding to political jitters that support gold, the United States on Tuesday imposed new North Korea-related sanctions, targeting Chinese and Russian firms and individuals for supporting Pyongyang's weapons programs. "On the other hand what has been supporting gold for the last six months or so is the risk aversion," Wing Fung's To said, referring to uncertainty around the Trump administration in particular.

Among other precious metals, silver was down 0.2 percent to $17 an ounce, while platinum slipped 0.3

percent to $976.90.

Palladium lost 0.3 percent to $935 after touching an

over 16-year high at $940 on Tuesday.
