NEW YORK, July 15 (Reuters) -World stock indexes and Treasury yields rose on Monday as investors weighed the prospect of Republican Donald Trump winning the U.S. presidential race after he survived an assassination attempt, while the dollar dipped after comments from Federal Reserve Chair Jerome Powell.

Longer-dated U.S. bond yields climbed on the assumption that Trump policies would add to government debt and inflation, while crypto stocks rallied along with bitcoin BTC=. Trump has presented himself as a champion of cryptocurrency.

Investors have viewed a Trump win as likely to mean more tax cuts and a looser regulatory environment. The S&P 500 energy sector .SPNY gained 1.6%.

On online betting website PredictIt, contracts for a Trump election victory traded at 68 cents, up from 60 cents on Friday, with a potential payout of $1. Contracts for a Biden victory were at 26 cents.

The assassination attempt in Pennsylvania on Saturday of Trump appeared to improve his chances for election. The motive behind a 20-year-old gunman's attempt on the life of Trump remained a mystery, with the suspect having been killed and the FBI unable to determine an ideology that may have been behind the attack.

"The publicity around the event is providing some kind of a boost," said Josh Wein, portfolio manager at Hennessy Funds.

But, he said, "the last four, five days the (stock) market has been rallying... so it's a continuation of a strong move from the back half of last week since we realized that maybe there is some reason to celebrate the idea that there could be one and now likely two rate cuts by the end of the year."

Investors digested comments from Powell, who said on Monday the three U.S. inflation readings over the second quarter of this year do "add somewhat to confidence" that the pace of price increases is returning to the Fed's target in a sustainable fashion.

Traders are also pricing in a second and possible third rate cut by December. FEDWATCH
