June 19 (Reuters) - Futures tracking Canada's main stock

index fell on Friday, as U.S.-Iran negotiations aimed at ending

the Middle East conflict were called off, fueling fresh

uncertainty at the end of a choppy week.

Futures on the S&P/TSX index fell 0.35% to 2,046.8

at ET 07:26 a.m. ET.

* Brent crude prices were flat at near $80 per

barrel, after Switzerland said U.S. talks with Iranian

negotiators would not take place on Friday, as Vice President JD

Vance dropped his travel plans.

* Expectations of a peace deal and a gradual reopening of

the Strait of Hormuz, a vital artery for global energy supplies,

supported global risk appetite this week.

* Gold prices fell more than 1%, putting the yellow metal on

track for a third straight weekly decline, pressured by a firmer

U.S. dollar and a hawkish Federal Reserve.

* Commodity prices tend to impact Canadian stocks due to the

presence of large energy and mining companies in the index.

* The main TSX index touched a series of record

highs this week before retreating in the past two sessions.

Friday's early declines threaten to wipe out the TSX's slim

weekly gains.

* Investors will keep a close eye on Canada's April retail

sales data, set to be published at 8:30 a.m. ET.

* The Bank of Canada last week left its key interest rate

unchanged as expected and said it was seeing limited evidence

that higher energy prices were fueling broad-based inflation.
