Folklore and modern horror are replete with tales of people summoning  ghosts by recanting their name or chanting a particular phrase. Centuries ago there was Bloody Mary. The 1980s brought us the Evil Dead trilogy and Beetlejuice, while Candyman appeared in the 90s.

And in the 21st century there is the euro zone debt crisis, conjured repeatedly by the phrase from Europe’s leaders, “The worst is over,” and variations thereof.

French President Francois Hollande was the latest to tempt the crisis apparition on Wednesday night:

Tonight, I have the confirmation that the worst is behind us.

Economic nightmares have followed for policymakers who’ve made similar statements in the past.

In April, European Central Bank board member Joerg Asmussen said, ”the worst of the crisis seems to be over,” shortly before Spanish government borrowing costs started soaring to new heights.
