European stock futures are broadly flat on Friday, as hopes of a solid economic recovery in Europe were offset by fears that rising inflationary pressure could prompt central banks to tighten monetary policy sooner than expected. Meanwhile, investors digested key economic data showing Germany's producer inflation jumped in May to the highest level since 2008, when prices rose strongly before the financial crisis. At the same time, UK retail sales unexpectedly dropped over the same period, as food stores and non-store retailers were affected by the easing of restrictions for hospitality and non-essential retail. In other news, post-Brexit tensions continued, after the UK asked the EU to suspend an imminent ban on some meat products in Northern Ireland, with both sides aiming to negotiate an agreement on the Brexit protocol and avert a trade war.
