0959 ET - A larger-than-expected 1.1% on-month fall in Canadian retail sales volumes in July isn't the end of the world, given the advance indicator implies that sales volumes fully rebounded in August, Capital Economics' Stephen Brown says. Still, the economist says consumer spending faces stronger headwinds from here on amid a renewed jump in gasoline prices. Brown says the sales data present only marginal downside risk to the flash estimate that monthly GDP was unchanged in July. And an advance estimate suggesting nominal retail sales rose 1.3% in August should equate to a similar sized rebound in sales volumes given goods prices were little changed.
