An increasing proportion of bonds have carried negative yields over the past few years. Negative-yield bonds have been a prominent feature in European bond markets since the European Central Bank (ECB) announced its public-sector purchase programme in early 2015. In mid-2019, expected yield on Dutch sovereign bonds with a ten-year term to maturity dipped below 0% for the first time. Bonds with negative yields have the benefit that issuers seeking to raise funds have relatively low costs. Conversely, bond investors are forced to accept low yields, and indeed negative ones at times.
Dutch residents had €624 billion in outstanding negative-yield bonds, as of 30 June 2021, measured by nominal value. This means 32% of the Dutch bond market carried negative yields. In November 2020, this volume peaked at €795 billion, or 43% of the total Dutch bond market. Volumes of negative-yield bonds depend heavily on price fluctuations and related expected market rates. As a result, they can change rapidly and strongly. Issuers usually know their interest payments from the issue date over the remaining term. These payment do not change, but expected yields can fluctuate rapidly and strongly as market rate expectations and other factors vary.
