* Negative sovereign credit rating actions curb risk trade
* Global stocks, commodities fall; oil down $2 a barrel
* Treasuries sell off after poor 10-year note auction
* US dollar halts three-day advance

NEW YORK, Dec 9 (Reuters) - A series of negative sovereign credit rating actions across Europe and the Middle East dampened appetite for higher-yielding assets on Wednesday and weighed on stock and commodity prices.
Even as investors became more averse to risk, U.S. Treasury prices fell following an unexpectedly weak auction of 10-year notes. The U.S. dollar posted losses after three consecutive sessions of gains.
European shares were hit by a Standard & Poor's warning it could downgrade Spain's AA-plus sovereign credit rating, one day after Fitch decided to cut Greece's rating to BBB-plus. For details, see [
].Adding to global credit fears, Moody's said it was reviewing the ratings of issuers related to the government not just of Dubai but of neighboring emirate Abu Dhabi and the federal government of the seven-member United Arab Emirates federation.
"The real issue is what this could do as countries turn to their taxpayers to raise revenue in order to protect their credit worthiness," said Kevin Caron, market strategist at Stifel, Nicolaus & Co in Florham Park, New Jersey.
"This could mean higher tax rates when we have to pay for the stimulus, and that would hurt growth going forward."
U.S. stocks posted lighter losses, however, as the market was supported by an unexpected rise in October wholesale inventories, which analysts said pointed to economic recovery. [

DOLLAR HALTS GAINS
But the U.S. dollar halted a three-day winning streak as investors concluded the recent rally is overdone.

Against the Japanese yen, the dollar <JPY=> was down 0.67 percent at 87.81. The euro <EUR=> was practically stable at $1.469, however.
"Neither of these developments, Spain or Greece and their sovereign credit ratings, can be interpreted as good for the euro," said Joseph Trevisani, chief market analyst at FX Solutions in Saddle River, New Jersey.
"But the market has known about these things for some time so there won't be too big a reaction."
Prices of U.S. Treasuries also fell, despite some safety bid, after the sale of $21 billion in 10-year notes attracted poor demand.
Analysts said the deal suffered from bad timing, given many professional investors are unwilling to commit funds for longer periods this close to the year-end.
The benchmark 10-year Treasury note <US10YT=RR> was last down 13/32, yielding 3.44 percent, compared with 3.89 percent late Tuesday. The 30-year Treasury bond <US30YT=RR> was down 30/32, yielding 4.43 percent against 4.37 percent late Tuesday.
