Highlights from the fixed income markets:
- Broad-based strength continued in fixed income for a third consecutive quarter, supported by falling Treasury yields and tighter corporate bond spreads.
- The Bloomberg U.S. Aggregate Index (the Agg) returned 2.03% for the quarter, with every sub-sector delivering positive absolute and excess returns. Year-to-date, the Agg is up over 6%, continuing the best year for fixed income returns since 2020.
- Corporate bond spreads tightened in every investment grade sector and now sit near all-time tights. The most significant tightening came from the communications sector. BBBs were the strongest performer by ratings category.
- High yield spread movements were mixed but leaned toward tightening overall. While sectors like capital goods saw modest widening, many others, including communications, experienced meaningful compression. Performance was strongest in the lowest-rated category, CCCs.
- Municipal bonds rebounded, posting positive returns after two consecutive quarters of losses. Year-to-date performance has turned positive.
Market Summary
All major fixed income sectors posted gains in the quarter, extending the market’s strong year-to-date momentum. Municipal bonds led performance for the quarter, rebounding after two consecutive down periods.

Bond Rating Categories
Standard & Poor’s Ratings Group
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.
