Investors have been holding unhedged US dollar assets to capture both high yields and currency appreciation, a speculative strategy traditionally used for emerging market local currency bonds. This parallel indicates a shift in risk perception, where US assets are no longer seen as a pure safe haven.

Despite a recent sell-off, German Bunds are seen as attractively valued compared to US Treasuries. The US-Germany spread is considered too tight, with US yields approximately 7 basis points too expensive versus their Euro counterparts, presenting a cross-market opportunity for fixed income investors to favor German debt.

Contrary to fears of a spike, a major rise in 10-year Treasury yields is unlikely. The current wide gap between long-term yields and the Fed's lower policy rate—a multi-year anomaly—makes these bonds increasingly attractive to buyers. This dynamic creates a natural ceiling on how high long-term rates can go.

Recent steepening in the U.S. yield curve is not just due to domestic factors. Fiscal uncertainty in Japan is pushing Japanese Government Bond (JGB) yields higher, making U.S. Treasuries less attractive on a currency-hedged basis for global investors, thus pushing long-term U.S. yields up.

A key macro theme is the decoupling of US and German interest rate paths. J.P. Morgan expects US Treasury yields to rise toward 4.5% due to a hawkish Fed and strong labor markets. Conversely, weak eurozone growth and lower fiscal pressure suggest German yields have scope to fall, creating a clear medium-term relative value opportunity.

The current US rates sell-off is characterized by rising real yields rather than just higher inflation expectations. This specific type of move is the most damaging for emerging markets because it tightens global financial conditions, making it difficult for EM rates to decouple from US pressure.

Global diversification away from the US dollar, accelerated by geopolitical tensions, is creating structural demand for Eurozone Government Bonds (EGBs). This acts as a buffer, making Euro area term premia less reactive to global rate sell-offs in markets like the US and Japan, a trend expected to continue.

Germany's finance agency signaled it would adjust debt issuance in response to a steepening yield curve. This sensitivity acts as a structural anchor on intermediate-term yields, creating a potential outperformance opportunity for German bonds versus US and UK debt, which face greater fiscal pressures.

During the recent broad bond sell-off, the 5-year Treasury sector counter-intuitively outperformed, making it appear historically expensive ('two standard deviations too rich') relative to the rest of the curve. This anomaly suggests it is vulnerable to a correction and could underperform going forward.
