Barclays trades the securities covered in this report for its US: Returning to the old normal •Long-end yields have reverted to pre-GFC levels, but their composition has fundamentallyshifted:Expected real returns on cash are significantly lower, with termpremia – both rate and fiscal – playing a larger role, particularly the latter. The inflation riskpremium is very well contained for now, but eroding insurance value is increasing the Scope remains for further repricing through neutral rates and fiscal premia:Investment-driven demand is likely to push estimates of r* higher versus the consensus, which remainstoo anchored to the post GFC–pre COVID era. There is room for the deficit outlook to worsen, 30y yields back near 5%: Same level,differentstory 30y yields have moved back near 5%, briefly revisiting levels last reached in 2007 and drawingrenewed market attention. The 5% threshold remains much watched, with evidence of demandfrom investors seeking to lock in long-duration yields at attractive levels. Here, we place current Long-end yields can be decomposed into the expected path of short rates (ie, the expectedreturn from holding T-bills) and the term premium required to bear duration risk. Bothcomponents can further be split into real and inflation elements. An alternative lens is todecompose term premia into rate-driven factors, capturing compensation embedded in swap Figures 3 to 5 present this decomposition over time and across key snapshots. Several points A significantly lower expectations component:While 30y yields are back near 2007 levels, theexpectations component (based on surveys) is materially lower. Current estimates point to~3.1% nominal, versus ~4.4% in 2007, 130-140bp lower. While surveys may be lagging andunderstating true market expectations, the magnitude of the gap suggests this is not purely a The rate term premium has normalized higher:The rate-driven term premium (30y swap rateminus the above expected rate) is now well above pre-COVID levels and also somewhat abovepre-GFC norms, indicating investors are being compensated for taking duration risk. 30y swaprates currently trade at ~110bp over the survey based expectations component, in between the Inflation compensation is well anchored:Long-term inflation expectations and risk premiumhave been well anchored and are not the reason 30y yields have risen from the lows. Mostforecasters continue to have faith in the Fed's inflation-fighting credibility and expect core PCEinflation to be near 2%.
