NEW YORK/LONDON, May 31 (Reuters) - Gold rose 1 percent on Tuesday, rebounding from the prior session's three-and-a-half-month low, but remained on track for its biggest monthly decline since November on dollar strength and growing expectations of an imminent U.S. interest rate hike.
Spot gold XAU= was up 1 percent at $1,216.80 an ounce at 2:38 p.m. EDT (1838 GMT), after Monday's fall to its lowest since Feb. 17 at $1,199.60. It was on track to close May down 5.9 percent.

U.S. consumer spending rose by the most in more than six years in April as households stepped up purchases of automobiles, suggesting an acceleration in economic growth. better spending number will leave Q2 tracking higher, but the lack of acceleration in core PCE (inflation) means that there's no rush for the Fed to hike as early as June," said Royce Mendes, director and senior economist at CIBC Capital Markets in Toronto.
An increase in U.S. rates would raise the opportunity cost of holding gold, which does not earn interest. It would also bolster the dollar, making gold more expensive for buyers in other currencies.
Gold has been under pressure since release of the minutes from the Federal Reserve's April meeting boosted expectations of an imminent rate rise. you get a pick-up in growth expectations in the U.S. and aggressive rate hikes from the Fed, then you could revisit the low of the year (at $1,127.80), but I see that as an unlikely scenario," ABN Amro analyst Georgette Boele said, adding the next support level is the 200-day moving average of $1,163.
