Sovereign bond markets remained under pressure over the New Year’s Eve week, with yields rising further across core and peripheral markets and extending the recent sell-off at the long end of curves. In the US, the move was led by intermediate and long maturities: the 10yr Treasury yield rose by around 6bps over the week to 4.19%, while the 30yr increased by a similar amount to 4.87%, both reaching their highest levels since early September. By contrast, the front end was relatively anchored, with the 2yr yield marginally lower on the week. As a result, curve steepening continued, with the US 2s10s spread closing above 70bps for the first time since January 2022. Inflation compensation also edged higher, with the US 10yr breakeven up 3bps, alongside a rise in real yields.
Reflecting these moves, broad Treasury ETF performance was mixed. Shorter-dated US government ETFs posted modest gains (e.g., 1–3y), while longer-duration ETFs underperformed, with the 10–20y and 20y+ segments bearing the brunt of negative returns.
European rates broadly followed the same pattern. The 10yr Bund yield rose 4bps to 2.90%, its highest level since October 2023, while the 30yr German yield pushed to levels last seen in 2011. Peripheral spreads were stable but yields increased across the board, with Italian and Spanish 10yr yields both up around 5–6bps. UK and Japanese yields also moved higher. Reflecting these dynamics, global aggregate bond indices posted modest negative returns, with losses concentrated in longer-duration Treasury and euro government bond ETFs, while short-dated segments proved more resilient.
In euro bond ETF land, short to medium euro government ETFs outperformed modestly, helped by yield moves at the front end, while longer-dated euro government and inflation-linked ETFs posted small negative returns.
Emerging market
Emerging market debt posted mixed results over the past week, with broadly stable spreads but returns constrained by higher global rates. In hard-currency markets, risk sentiment was generally unchanged, with CDX USD EM finishing the week flat. Against this backdrop, the Bloomberg Emerging Markets Hard Currency Aggregate Index eked out a small positive return.
Performance across EM bond ETFs was more uneven and increasingly differentiated by duration and credit quality. The iShares Emerging Market Sovereign Bond ETF delivered a modest negative return, reflecting its relatively long duration and sensitivity to the rise in US Treasury yields. Similarly, the EM corporate bond ETF slipped slightly, as higher core yields outweighed stable spread conditions.
