• Monetary policy was at the top of the agenda this week, as Federal Reserve Chair Janet Yellen testified before Congress in her semi-annual address. The Fed chief stoked fresh gains on Wall Street by telling lawmakers that monetary policy will be slow to change in the coming years.

• Yellen also expressed deeper worry over slowing inflation, something analysts say could deter the central bank from raising interest rates in a more aggressive fashion.

• The Dow Jones Industrial Average and Nasdaq Composite Index rose to record highs this week, while the S&P 500 approached its highest level in nearly one month.

• The CBOE volatility gauge fell below 10.00. The so-called fear index trades on a scale of 1-100, where readings below the 20 mark indicate complacency in the market.

• Dovish Fed-speak also sent European stocks higher on Wednesday, with the major bourses enjoying their best one-day advance in two-and-a-half months.

• In commodities, oil prices rose to more than one-week highs on signs of better demand. U.S. West Texas Intermediate (WTI) futures settled above $46.00 a barrel on Thursday. Earlier in the week, the U.S. Energy Information Administration (EIA) said commercial crude stockpiles fell by 7.56 million barrels in the week ended July 7.

• Encouraged by a rebounding economy, the Bank of Canada (BOC) raised interest rates on Wednesday for the first time in nearly seven years. In doing so, Canada becomes only the second G7 nation to begin normalizing monetary policy.

• The BOC rate hike sent the Canadian dollar to nearly one-year highs against the greenback, which declined against a basket of world currencies through the week.

• China’s trade surplus widened more than expected last month even as import growth outpaced exports, official data showed. Beijing’s dollar-denominated trade surplus grew to $42.77 billion in June from $40.79 billion the month before.
