Aug 24 (Reuters) - Gold rose to its highest in more than three months on Monday, building on gains from last week as a muted dollar boosted appeal, while investors awaited U.S. inflation data and remarks from Federal Reserve Chairman Kevin Warsh this week for signals on the interest-rate path.
Spot gold was up 0.7% at $4,635.25 per ounce by 0838 GMT, hitting its highest level since May 15, while U.S. gold futures rose 0.2% to $4,691.10.
Bullion rose more than 5% last week after the U.S. Treasury Department's buyback support plan pushed the dollar lower, making greenback-priced bullion more affordable for foreign investors.
"The consolidation of gold prices above $4,600, and the potential for further gains, will depend to a large extent on the U.S. dollar remaining under pressure and Treasury yields stabilizing at current levels or declining further," ActivTrades senior analyst Ricardo Evangelista said.

Market participants are now awaiting the July Personal Consumption Expenditure price index due on Wednesday and Warsh's speech at the Jackson Hole Symposium on Friday to gauge the policymakers' outlook on interest rates.
Traders are pricing in about a 36% chance of a rate-hike in September, with a 64% chance of the Fed leaving rates unchanged, according to the CME FedWatch Tool.
Although gold is typically seen as an inflation hedge, higher interest rates tend to diminish bullion's appeal due to its non-yielding characteristic.
On the geopolitical front, the U.S. threatened Iran with what it called "the greatest financial offensive ever marshalled" as it prepared to roll out economic sanctions on Monday that target Iran's trade partners.
