KEY POINTS
  • Rhetoric between the U.S. and Iran could ramp up even more in early August as a first round of sanctions on Iran is set to kick in — and that could create even more oil price volatility.
  • Iran could also use that as an opportunity to restart its nuclear program, analysts say, which it agreed to end in 2015 when the U.S. and five other nations agreed to lift sanctions.
  • "August is never calm," said Barclays oil strategist Michael Cohen. "Summer in the Middle East, you just never know what could happen."

After a weekend of threats, the rhetoric between the U.S. and Iran could ramp up even more in early August as a first round of sanctions on Iran is set to kick in — and that could create even more oil price volatility.

There's a risk too that Iran in the near future could use the introduction of sanctions as an excuse to restart ts nuclear program, which it agreed to end in 2015 when the U.S. and five other nations agreed to lift sanctions. President Donald Trump withdrew the U.S. from that agreement in May and said the U.S. would reinstate financial sanctions. The other countries — China, Russia, Germany, France and the U.K. so far remain in the deal with Iran, and they have been making efforts to limit the impact of sanctions.
