European equity markets were poised to open slightly higher on Wednesday, with Euro Stoxx 50 and Stoxx 600 futures each up around 0.1% in premarket trading. The move followed a sharp decline in global bond yields as traders assessed the implications of the US government’s expanded debt buybacks. Lower oil prices also supported sentiment amid hopes for renewed diplomatic efforts in the Middle East and easing concerns about higher near-term inflation. Investors were awaiting a key US inflation reading and Nvidia’s earnings report, both of which could provide fresh catalysts for global markets. No major economic data releases or corporate earnings reports were scheduled in Europe on Wednesday.
