Onset of US/China Trade War in May Triggers Noticeable Steepening in the IHS Markit iBoxx™ USD Investment Grade Index

23 May 2019 Chris Fenske

The rally in US investment grade bond spreads appears to have stalled following the breakdown of the US/China trade negotiations announced in early May.

As shown in figure one, the average option adjusted spreads (OAS) for constituent data from the IHS Markit iBoxx USD Investment Grade Index hit their widest point in years on January 4, 2019, but then began to contract and continued to rally through the end of April 2019.

However, as seen in figure 2 below, the month of May has seen the most prolonged period of widening since the significant global equity and credit markets sell-off that began in October 2018:

  • OAS spreads for USD BBB rated bonds had tightened 73bps to close at an average OAS spread of 145bps on April 30, 2019.
  • BBB spreads have since widened 15bps to close at an average OAS of 158bps on May 22.
  • Software and insurance were the hardest hit AAA rated constituent sectors, which both widened 11bps to an average OAS of 67bps and 55bps on May 22, respectively.
  • Non-ferrous metal companies were among the worst performers of the BBB rated cohort, widening 40bps during the month to an average OAS of 231bps on May 22.
