Recent moves in interest-rate differentials have increased the cost of hedging dollar-denominated bonds into euros. That means European fixed-income investors need to rethink their global diversification strategy—but not abandon it altogether.
Ever since Mario Draghi’s vow in 2012 to do “whatever it takes to preserve the euro”, European fixed-income investors have become used to abnormally low domestic bond yields. As yields dwindled on traditional European fixed-income assets, such as government bonds and investment-grade corporate bonds, euro investors started to globalize their portfolios to benefit from higher-yield opportunities outside Europe. By shifting allocations into USD-denominated bonds issued by US corporates and emerging-market names, European investors could tap returns that were unavailable from domestic assets.
But more recently, exuberant hedging costs have called this strategy into question. The annual cost of hedging a USD-denominated investment into euros was around 2.8% as of 22 May 2018, a 2.3% increase from 29 May 2015. So a bond yield in US-dollar terms may still look attractive, but if European investors hedge their currency risk, they may lose most of the yield advantage.
