Citable research brief

Core conclusion · Tlines extraction

UBS CIO advises that despite rising long-term government bond yields, quality bonds remain attractive, especially short- and medium-maturity issues. They highlight that yields would need to rise significantly to erode returns, and expect yields to decline as central bank policy expectations are reassessed. Selectivity is key, with opportunities in Eurozone duration, EM, and high yield credit.

Key arguments

Long-term yields have risen sharply but front end is anchored, not invalidating quality bonds.
Historical starting yields indicate income cushion; US 2y and 5y yields need to rise 100-230 bps to offset income.
Market pricing for central bank hikes looks too aggressive; yields should decline as expectations adjust.
Corporate fundamentals remain healthy with tight spreads and good balance sheets, but selectivity needed.

Key numbers

30y US Treasury yield: 5.31%
30y German Bund yield: 3.75%
30y UK gilt yield: 5.85% (May peak)
Rate increase needed to offset income: 100-230 bps

Main risks

Persistent inflation and government deficits keep long-term yields elevated.
Central bank rate hikes could be more aggressive than expected.
Corporate credit spreads may widen if fundamentals deteriorate.
Low liquidity in long-end bonds increases volatility.
