June 30 (Reuters) - Canadian stock index futures rose on

Tuesday, as higher commodity prices and easing geopolitical

tensions put the main benchmark on track for a strong quarterly

performance.

Futures on the S&P/TSX index were up 6.20 points, or

0.30%, at 06:29 a.m. ET, signaling a positive open for the

markets.

* Optimism around AI and signs of a resilient global economy

despite several headwinds have supported global stock markets

this year.

* Canada's S&P/TSX Composite Index was on track

for its eighth straight quarter of gains, the benchmark's

longest winning streak since January 1995-October 1996.

* The index was poised for a 6.3% rise in the second

quarter, still lagging U.S. peer S&P 500, which is on

track for a 14% gain.

* The rally in oil prices on the back of the Middle East

conflict has helped Canada's energy index outperform

this year with a near 25% jump.

* But crude prices have retreated sharply in recent weeks on

signs of progress in ending the Middle East conflict, weighing

on Canada's commodity-heavy stock index. Brent crude

prices edged up to $73.16 on Tuesday.

* Gold miners, which carry sizeable weight in the TSX index,

have come under pressure as spot gold prices head for their

worst quarter since 2013.

* Investors will also keep a close eye on U.S. economic data

this week, including the June non-farm payrolls report, for

clues on the Federal Reserve's monetary policy path. Canada's

April GDP data is due at 8:30 a.m. ET.

* Meanwhile, U.S. President Donald Trump's administration is

expected to formally declare on Wednesday that it will not

extend the U.S.-Mexico-Canada Agreement (USMCA) on trade,

starting a decade-long clock to wind down the 32-year-old North

American free trade zone as the three countries haggle over

proposed changes.
