High-yield spreads near two-decade lows

Bloomberg reported on May 21 that junk debt was outperforming most other fixed-income sectors even as a jump in U.S. Treasury yields erased gains across much of the bond market. The move left high-yield credit spreads near two-decade lows, a level that has started to draw warnings from investors and analysts about how much compensation buyers are still getting for default risk. The backdrop was a sharp rise in government bond yields tied to inflation and oil-price concerns, while lower-rated corporate debt held up better because its higher coupons cushioned price declines. The result was a market in which risky credit was acting more defensively than safer bonds. ### Why were junk bonds holding up while Treasury yields were rising? Bloomberg said on May 21 that lower-rated debt had extended its outperformance over investment-grade bonds this week to 1.6 percentage points, the widest such gap so far in 2026. That outperformance came as rising benchmark yields hit longer-duration bonds harder, while high-yield debt benefited from larger income payments and shorter effective interest-rate sensitivity. Nuveen said in its May 18 weekly fixed-income commentary that the 10-year Treasury yield rose 24 basis points to 4.59% and the 30-year yield reached 5.12% during the week. Nuveen said high-yield bonds returned negative 0.49% for the week, but that was still better than investment-grade corporates at negative 1.04% and the Bloomberg Aggregate Bond Index at negative 1.14%. ### What exactly is a high-yield spread? FRED says the ICE BofA U.S. High Yield Index option-adjusted spread measures the extra yield investors demand to own below-investment-grade corporate debt instead of Treasuries. The series covers U.S. dollar-denominated corporate bonds rated below investment grade, weighted by market capitalization. The May 21 reading was 2.78%, according to FRED, and the St. Louis Fed page says the figure was updated on May 22. A spread at that level means investors are receiving 2.78 percentage points of compensation above comparable Treasuries for taking on high-yield credit risk. ### Why does a low spread matter now? The 2.78% reading matters because spreads are the market’s main cushion against defaults, downgrades and recession risk. When spreads are tight, investors can still earn an attractive all-in yield if Treasury rates are high, but they have less protection if the economy weakens or corporate balance sheets deteriorate. Bloomberg said investor unease was building because the market’s strong recent performance had pushed spreads near two-decade lows even as broader bond-market volatility increased. That tension is the core issue in the current rally: buyers are still collecting relatively high nominal yields, but the extra premium for credit risk has become unusually thin. ### Why can high-yield still look attractive if spreads are tight? State Street Global Advisors said last month that high-yield spreads were roughly 38% below their long-term average, but yields remained elevated enough to keep credit attractive for income-focused investors. That distinction matters because total yield on a junk bond is made up of the Treasury base rate plus the credit spread. Treasury yields near multiyear highs can keep all-in high-yield yields appealing even if spreads are compressed. That helps explain why investors have continued to buy products such as HYG and JNK and why price declines in junk debt have been smaller than in more rate-sensitive bond sectors. ### What should investors watch next? FRED says the next release for the ICE BofA U.S. High Yield option-adjusted spread is scheduled for May 25. Treasury yields, weekly fund-flow data and any further moves in oil prices will help determine whether high-yield bonds keep outperforming or whether tighter spreads start to reverse if risk appetite fades.
