By Pablo Sinha

April 30 (Reuters) - Gold prices jumped on Thursday as the dollar eased and oil prices ticked lower, with some analysts also pointing to an uptick in safe-haven demand on growing concerns that the U.S.-Iran war could escalate.

Spot gold XAU= climbed 1.9% to $4,629.83 per ounce, as of 1158 GMT, after falling to its lowest since March 31 in the last session. Bullion was down about 0.9% so far this month.

Gold has so far fallen about 12% since the conflict began. Although the metal is viewed as a safe-haven during times of uncertainty, rising energy prices have stoked fears of inflation and the prospect of higher interest rates, which would weigh on the non-yielding metal.

Some analysts, however, say safe-haven demand could be picking up.

"Gold is behaving a bit more like we should expect it to behave. It should be rising in times of geopolitical risks, and clearly that geopolitical risk is that there's speculation that the U.S. is getting ready for the next level of escalation," said Nitesh Shah, commodity strategist at WisdomTree.

Meanwhile, the U.S. Federal Reserve Chair Jerome Powell closed out eight years on Wednesday with interest rates on hold. Markets now await Personal Consumption Expenditures data for March, due at 1230 GMT.
