European markets were mixed on the 17th. In London, the FTSE 100 extended gains, while the mid-cap FTSE 250 index fell 0.47 percent, its first decline in seven trading days. The STOXX Europe 600 index slipped 0.34 percent, weighed down by the global tech sell-off. In euro zone bond markets, rising oil prices amid Middle East tensions fueled expectations of further rate hikes by the ECB, pushing up sovereign yields across the region, with the German two-year yield climbing 10 basis points on the week.
