Global Bonds Set for Worst Week in a Month as US-Iran Risks Rise

Global bond markets are heading for their worst week in a month as investors grow increasingly uneasy about a stalemate between the US and Iran.

Yields climbed across major markets this week, with those on two-year US, German and UK bonds heading for the biggest weekly increases in a month. Treasury two-year yields have risen 11 basis points since Monday to 3.81%, while UK two-year yields have risen 26 basis points to 4.37%.

Traders are reassessing the outlook for interest rates in the face of renewed tensions in the Middle East. The bond selloff reflects mounting concern that prolonged disruption to energy supplies will keep inflation elevated, hindering the ability for central banks to lower interest rates, and potentially even requiring some to hike. Brent crude prices are on track for their biggest weekly gain since the first week of the conflict.

“I do worry that in the coming days the Iranians will really sink their heels in and call Trump’s bluff,” said Ariel Bezalel, investment manager for fixed income at Jupiter Asset Management. “We’re taking some profits and reducing a bit of our rates exposure, as well as our credit risk.”

Bezalel says he’s holding more cash than he has done in recent weeks, nervous that wild bond-market swings seen in March will return.
