Swiss stocks - Factors to watch on July 9

ZURICH, July 9 (Reuters) - The following are some of the main factors expected to affect Swiss stocks on Thursday:

UBS (UBSN.VX)(UBS.N)

* A judge ordered the U.S. government to say whether it was prepared to shut Swiss bank UBS AG in the United States as part of a battle to learn the identity of 52,000 secret accounts suspected of being used by Americans to avoid taxes.

* The Swiss Parliament may not approve a double taxation treaty between Switzerland and the United States if the legal action against Swiss bank UBS is not resolved, Swiss minister for economic affairs Leuthard said on Wednesday.

* UBS may be able to pay up to $5.5 billion to end a damaging U.S. tax dispute without needing an immediate cash injection, thanks to a recent capital increase and proceeds from asset sales.
