PERTH, July 27 (Reuters) - Oil rose for a third session on Monday, riding the tailcoat of rallying Asian stocks toward $69 a barrel as investors read recent positive corporate earnings as a further sign of an economic recovery that will stoke fuel use.
Asian stocks rose for the ninth day in 10 on Monday, with investors still focused on upward momentum in corporate earnings and moving money into riskier, higher-yielding assets. [
]U.S. crude for September delivery <CLc1>, which has risen in eight of the last nine trading days, climbed 63 cents to $68.68 a barrel by 0553 GMT, the highest since early this month.
London Brent crude <LCOc1> rose 77 cents to $71.09.
"Oil's rally has again been supported by external factors, such as positive macroeconomic data and rally in the equities markets, and those factors, along with the U.S. dollar, should again set the tone for oil this week," said Toby Hassall, a commodities analyst at Commodities Warrants Australia.
Rosy macroeconomic data and upbeat earnings results have buoyed hopes of a rebound in the economy, prompting investors to bet that fuel demand will recover later this year. Oil prices have climbed about $10 since a mid-month low.
But Wall Street may take a breather this week after an earnings driven rally lifted the major U.S. stock indices to their highest levels in months. [
]In addition to a steady flow of companies results this week, including Exxon Mobil Corp <XOM.N> and Honda Motor Co <7267.T> and Mitsubishi UFJ Financial <8316.T>, analysts said investors will also look out for U.S. domestic gross product data for the second quarter to see if a second-half recovery is on track.
Some analysts said a faster rebound in Asian economies, led by China, would offer further support for oil prices in coming months.
"The central factor in determining the speed of adjustment in oil products will be the pace of recovery in Asia," Barclays Capital said in a research note.
"The sensitivity of oil demand to economic growth is greater in Asia than in other regions, and the tendency for economic growth to surprise consensus estimates on the upside also appears to be greater in Asia."
Separately, on the geopolitical front, more than 50 Nigerians were killed on Sunday in clashes between security forces and militants in the northeastern city of Bauchi, residents and hospital sources said. [
]Despite the price rally moving into its third week, speculators have pared back their bullish bets in the crude oil market, cutting net long positions to a scant 2,218 lots in the week to July 21, regulatory data showed Friday. [
