May highlights from the fixed income markets:

 

  • Fixed income returns were mixed in May; Treasuries were negative, high yield (HY) corporates were strong, and investment grade corporates and municipals were essentially flat.
  • Treasury yields moved higher across the curve, most notably in the 2-year to 10-year maturities.
  • The Bloomberg U.S. Aggregate Index (the Agg) lost 0.72% for the month, driven primarily by losses on Treasuries and mortgage-backed securities (MBS). Despite the weakness in May, the Agg remains up nearly 2.5% year-to-date.
  • Corporate spreads reversed the general widening trend of the past two months, tightening in every sector across both investment grade (IG) and high yield (HY). Spreads remain moderately wider year-to-date across all IG sectors. In HY, spread moves have been more volatile; all but two sectors (communications and consumer non-cyclicals) remain wider on the year.

        Bond Rating Categories

        AAA An obligation rated “AAA” has the highest rating assigned by Standard & Poor's. The obligor's capacity to meet its financial commitment on the obligation is extremely strong.

         

        AA An obligation rated “AA” differs from the highest rated obligations only in small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.

         

        A An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher- rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

         

        BBB An obligation rated “BBB” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

         

        Obligations rated “BB,” “B,” “CCC,” “CC” and “C” are regarded as having significant speculative characteristics. "BB" indicates the least degree of speculation and “C” the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

         

        BB An obligation rated “BB” is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

         

        B An obligation rated “B” is more vulnerable to nonpayment than obligations rated “BB,” but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation.

         

        CCC An obligation rated “CCC” is currently vulnerable to nonpayment and is dependent upon favorable business, financial and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

         

        CC An obligation rated “CC” is currently highly vulnerable to nonpayment.

         

        C A subordinated debt obligation rated “C” is currently highly vulnerable to nonpayment. The “C” rating may be used to cover a situation where a bankruptcy petition has been filed or similar action taken, but payments on this obligation are being continued.

         

        D An obligation rated “D” is in payment default. The “D” rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless Standard & Poor's believes that such payment will be made during such grace period. The “D” rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.
