Chicago soybean futures were almost unchanged on Wednesday as traders adjusted positions before the Thanksgiving holiday while remaining cautious about Chinese purchases of U.S. beans under a bilateral trade truce.

The oilseed market remained underpinned by further indications of Chinese demand, with traders telling Reuters that China bought at least 10 cargoes of U.S. soybeans since Tuesday. That followed a call on Monday between Presidents Donald Trump and Xi Jinping, during which Trump said he had pressed Xi to accelerate and increase Beijing’s purchases of U.S. goods.

However, soybean futures were holding well below last week’s 17-month high amid doubts that Beijing will buy the 12 million metric tons cited by Washington as an agreed target for end-December.

“Today we’re talking about maybe 3 million tons booked,” a European trader said. “It’s keeping prices supported temporarily but it’s not enough. In the past this would have been considered normal flows.”

The most-active soybean contract on the Chicago Board of Trade (CBOT) ZS1! was up 0.04% at $11.25-1/4 a bushel at 1224 GMT, after rising as high as $11.69-1/2 last week.

The recent rally in U.S. prices has fuelled doubts over demand, with South American supply becoming cheaper for China and other destinations.

“U.S. beans are the most expensive China can buy,” said a trader in Australia, adding that he expected Chinese purchases to fall short of expectations and for prices to fall.

In cereals, CBOT wheat ZW1! was unchanged on the day at $5.39-1/4 a bushel and CBOT corn ZC1! inched up 0.06% to $4.38-1/2 a bushel.

The Chicago Board of Trade will close for the U.S. Thanksgiving Day holiday on Thursday and trading is expected to be thin during a shortened session on Friday.

The corn market was monitoring a sharp fall in exports from Ukraine due to a rain-delayed harvest and Russian strikes on railway infrastructure, but ample supply in other exporters like the United States and Brazil was keeping a lid on prices, traders said.

In wheat, falling Russian prices, harvesting in Argentina and Australia, and results from a Saudi import tender on Monday have kept attention on strong competition in a well-supplied market.
