SYDNEY : The dollar was looking to extend its bull run on Monday as lofty Treasury yields and a more restrained outlook for U.S. rate cuts burnished its attractiveness, though the risk of intervention had caused a pullback against the yen. Yen bears were tense in case Bank of Japan Governor Kazuo Ueda used a speech later Monday to flag a possible rate hike in December, in part due to the weakness of the currency. Ueda will deliver a speech at 0100 GMT, followed by a media conference at 0445-
