U.S. strikes Iranian tankers; Treasury yields rise

The report did not identify the tankers, the strike location, the weapons used, the resulting damage or any casualties. It also did not state that Iran’s attacks caused or prompted the new U.S. operation.

The officials did not name the aircraft carrier or guided-missile destroyer, disclose the attack location, identify the missiles or provide a count. The account said the reported launches did not hit any American warships.

The officials said Tehran’s recent attempts were raising alarm that it was using more sophisticated weapons and could be receiving assistance from China or Russia. The newsletter did not report confirmation of such assistance or provide details about it.

Brent crude jumped above $99 a barrel on Sept. 8, briefly reaching its highest level since July before retreating from that level. The benchmark was around 35% above its lows this summer, according to the newsletter.

The Wall Street Journal said the oil rebound was already showing up in gasoline prices. The expected effect on inflation sent Treasury yields higher, according to the newsletter. Oil-sensitive stocks took a hit before recovering some ground.

The newsletter did not quantify the new operation’s effect on oil supply or prices or attribute the price move to either the strikes or Iran’s missile attacks.
