Gold dipped in Asia on Friday, but remained well supported on Middle East tensions between Iran and Saudi Arabia and await a summit in Vietnam among Asia-Pacific nations.

Gold futures for December delivery on the Comex division of the New York Mercantile Exchange fell 0.11% to $1,286.13 a troy ounce.

Overnight, gold prices rose to three-week highs on Thursday amid a slump in the dollar on fears that the Senate would delay corporate tax cuts until 2019.

Gold prices added to gains from Wednesday’s session after the dollar fell on reports that Senate Republicans on Thursday will propose delaying a cut in the corporate tax rate from 35% to 20% until 2019.

The news of a possible delay to corporate tax cuts halted recent risk-on sentiment, fueling a flight-to-safety as traders appeared to unwind their bullish bets on riskier assets which followed on expectations that President Trump’s tax-reform plans would be enacted before year-end.

Gold prices are sensitive to moves lower in the U.S. dollar – A lower dollar makes gold cheaper for holders of foreign currency, thus, increases demand.

Also supporting demand for safe-haven gold was ongoing political unrest in the Middle East after Saudi Arabia advised citizens not to travel to Lebanon and urged the international community to impose fresh sanctions on Iran.
