United Kingdom

In a televised statement from Downing Street, UK PM Theresa May said Britain has increased its security threat level to the highest possible "critical" from "severe", following Monday's suicide attack in Manchester that killed 22 people, and she also said members of the army would be positioned at key sites to free up police for patrols and military personnel might be deployed at public events such as concerts and sports events as a further attack was seen as potentially imminent.

Confirming what CBS reported earlier today, UK police and Whitehall officials said that the suspected bomber who killed at least 22 people is 22-year-old Salman Abedi (or Salman Ramadan Abedi) from a family of Libyan origin. Abedi had not been identified by the coroner so no further details would be given, Greater Manchester Police said.

Following the horrific events last night in Manchester in which a bombing at an Ariana Grande concert, primarily attended by teenagers, claimed the lives of at least 22 people, we're just now learning that the Islamic State is claiming responsibility for the attack.

S&P futures rose alongside European stocks as Asian shares posted modest declines. The euro set a new six-month high and European bourses rose as PMI data from Germany and France signaled that the ECB will have to tighten soon as Europe's recovery remains on track, with the German Ifo business confidence printing at the highest level on record, and hinting at a GDP print in the 5% range. Oil declined after the Trump budget proposal suggested selling half the crude held in the US strategic petroleum reserve.

Global stocks were mixed to start the week, with Asian stocks higher, European stocks initially advancing then fading gains, while S&P futures are little changed after the biggest weekly drop since April (which for those keeping record was -0.4%). European shares, the euro and the pound all stumbled on Monday as rumblings in Spain, Britain and Brussels reminded investors that the region still has plenty of political uncertainty left in the tank.
