* TSX rises 0.5% to 22,079.81

* Two-year yield falls to 4-month low

* Loonie touches its weakest since May 23

* BoC cuts its policy rate to 4.75%

TORONTO, June 5 (Reuters) - Canadian stocks and bonds rallied on Wednesday, while the loonie weakened to a near two-week low against its U.S. counterpart, after the Bank of Canada became the first central bank among G7 countries to cut interest rates, raising prospects for Canada's economy.

The Toronto Stock Exchange's S&P/TSX composite index was up 101.63 points, or 0.5%, at 22,079.81, clawing back some losses since the start of the week.

The Canadian central bank lowered its benchmark interest rate by 25 basis points to 4.75%, its first cut in four years, in a move that will ease pressure on highly indebted consumers.

"It was clearly a positive development for equity markets and bonds," said Angelo Kourkafas, senior investment strategist at Edward Jones in St. Louis, Missouri. "It is consistent with a soft landing scenario that the Bank of Canada is willing to start (to) normalize policy while economic growth still is holding up."

The Canadian services economy grew in May for the first time in a year as firms saw an increase in new business and hired workers at a faster pace, data from S&P Global showed.

Nine of the 10 major sectors on the Toronto market moved higher, including the interest rate-sensitive real estate sector and resource stocks, as commodity prices climbed.

Wall Street also rallied, led by technology shares.

The Canadian 2-year yield fell 11 basis points to 3.946%, its lowest level since Feb. 2, as investors bet that the BoC would ease rates further in the coming months.

Swap market data shows that the central bank is expected to cut 75 basis points in total this year, compared with 47 basis points of easing that is priced in for the Federal Reserve.

That prospect of interest rate divergence weighed on the Canadian dollar. The currency was trading 0.2% lower at 1.37 to the U.S. dollar, or 72.99 U.S. cents, after touching its weakest intraday level since May 23 at 1.3741

"We think the BoC will cut rates at least once more before the Fed meets on Sept. 18, leaving CAD vulnerable to a further widening in rate differentials," said Simon Harvey, head of FX analysis for Monex Europe and Monex Canada.

The Federal Reserve's next policy meeting is June 11-12, when it is widely expected to leave rates unchanged. The Fed will also hold a policy meeting in late July, followed by its meeting on Sept. 17-18.

A majority of forecasters in a Reuters poll expect the Fed to cut its key interest rate in September, followed by one more cut this year.

The loonie is set to strengthen less than previously expected over the coming year as the BoC leads the Fed on rate cuts and if the U.S. election in November raises global trade uncertainty, a Reuters poll found. (Reporting by Fergal Smith; Editing by Sriraj Kalluvila and Leslie Adler)
