* Spanish markets climb on Catalonia relief
* Major Wall Street indexes lower on the session
* Rate decisions from BOE, BOJ and Fed this week (Updates with European market close)
NEW YORK, Oct 30 (Reuters) - A gauge of global equities hit an intraday record, as a bounce in Spain helped buoy European stocks, while Wall Street edged lower after a technology-led rally last week and a report the U.S. House of Representatives was discussing a gradual tax cut.
Bloomberg reported the schedule would put the tax rate at 20 percent in 2022, and the rate may be reduced by 3 percentage points a year starting in 2018.
"While the rate is important, it is changes to the code, how they are going to talk about repatriating cash, what that is going to mean, what kind of incentives are going to be put in place ... those are the more important factors that Wall Street is going to be looking for," said Keith Bliss, senior vice-president at Cuttone & Co in New York.
The Dow and S&P 500 retreated, on the heels of seven straight weeks of gains that left both indexes at record levels. The Nasdaq was slightly below the unchanged mark after scoring its best weekly gain in nearly a year last week.

Spain's benchmark 10-year bond yield last yielded 1.49 percent, down from 1.502 percent late on Friday.
