The dollar rose on Friday after a four-day losing streak, while perceived safe-haven currencies such as the yen gained as investors grew cautious ahead of what is expected to be a contentious G7 meeting in Canada later in the session. Despite Friday's gains, the dollar was on track for its largest weekly drop since late March.
Next week's expected hike in US interest rates by the Federal Reserve, a European Central Bank policy meeting and a Brexit bill vote all pose risks for currency traders and could inject more volatility in the market.

US President Donald Trump lashed out at Canada and the European Union on Friday, setting the tone for a hostile Group of Seven (G7) summit and raising the specter of a trade war that has unnerved Washington's top allies as well as investors. In mid-morning trading, the dollar rose 0.3 percent against a basket of currencies to 93.67. But it was poised to notch its biggest weekly drop in 11 weeks.
Trade disputes between the United States and its major partners will be in the spotlight, with the Mexican peso and the Canadian dollar leading losers. The peso fell to its weakest level against the dollar in 16 months on Friday. The euro fell 0.3 percent to $1.1758 after rising to a three-week high of $1.1840 overnight as investors took profits into this week's bounce. It was up more than 1 percent on the week and was set to post its biggest weekly gain since mid-February.
