China is expected to resume building its strategic oil reserves next year, a development that stands to speed up the march toward triple-digit oil prices. It is no secret that China is building an emergency stockpile of oil akin to the U.S. Strategic Petroleum Reserve, though the Chinese government is secretive about the timing for filling its storage tanks. However, a growing chorus of oil analysts say the next phase of China's reserve building--an addition of 168 million barrels to state inventories--is likely to begin in the first half of 2011
China is expected to resume building its strategic oil reserves next year, a development that stands to speed up the march toward triple-digit oil prices.

It is no secret that China is building an emergency stockpile of oil akin to the U.S. Strategic Petroleum Reserve, though the Chinese government is secretive about the timing for filling its storage tanks. However, a growing chorus of oil analysts say the next phase of China's reserve building--an addition of 168 million barrels to state inventories--is likely to begin in the first half of 2011.

That stocking up, coupled with growing commercial inventories owned by Chinese oil companies, could boost the price of crude oil by as much as $6.50 a barrel over 2011 and 2012, according to China International Capital Corp., a Beijing-based investment bank.

The renewed focus on the strategic reserve will further cement China's role as a driving force behind oil-market rallies. China's robust economic growth and its ravenous appetite for petroleum were a major factor behind oil's rise to above $90 a barrel this year as well as the record-setting run to nearly $150 a barrel in 2008. Analysts widely expect crude prices to enter triple-digit territory in 2011 if China's rapid growth continues and economies in the developed world continue to recover. February crude futures ended Wednesday down 37 cents at $91.12 a barrel.

"We're going to be watching how many shipments are going into China," said Mark Waggoner, president of Excel Futures, a broker based in Bend, Ore.

China is looking to bulk up its strategic reserves as a buffer against sudden disruptions of oil supplies, a growing concern as the country imports more of its crude. The U.S. established its reserves in 1975 after the Arab oil embargo. It now holds 726.5 million barrels of oil, enough to cover nearly 40 days of demand, according to the Department of Energy. China built its strategic reserve to 108 million barrels in 2009, enough to cover about 12 days of demand.

The size of its strategic reserve will total about 272 million barrels after the second phase is complete, according to several analysts' estimates. A third phase later this decade should add another 228 million barrels, China International Capital Corp. analysts said.

"It's very important for social stability and economic growth," said Joseph Stanislaw, an energy consultant. "Right now there's plenty of supply. This is the time to do it."

Given the secrecy surrounding the government's oil purchases, China's reserve building is something of a wild card in the oil market. However, a daily addition of 150,000 barrels--enough to fulfill one-third of the second phase in 2011--would still amount to nearly 10% of the International Energy Agency's forecast increase in global demand next year.

A few factors could mitigate the effect of large builds in China's stockpiles. If oil supplies begin to look tight, members of the Organization of Petroleum Exporting Countries can increase production. However, Saudi Arabia, which has the lion's share of spare capacity, indicated at an OPEC meeting earlier in December that the organization isn't concerned about global supplies.

China itself could back off from filling its reserve if prices keep rising. The country finished the first phase of its stockpiling after prices had collapsed from nearly $150 a barrel in late 2008 and early 2009. If crude gets too expensive in 2011, China could play the waiting game again, said Kang Wu, a senior fellow at the East-WestCenter in Honolulu, who tracks Chinese energy issues.

"They were pretty proud that they didn't buy when the price was above $70," Wu said. "It doesn't mean it's the policy. They buy as they see practical."
