German trading ban roils markets
Because no one followed suit, Germany’s unlateral ban on “naked” short selling of European government bonds – speculative bets that prices will fall on borrowed assets which then can be sold back to the lender with the speculator pocketing the difference –rocked global markets. Mark Williams, who teaches finance at the BU School of Management and is author of “Uncontrolled Risk” about the lessons to be learned from the fall of Lehman Brothers, says this shows that systemic risk remains high in our global financial market.
“Short sellers are a symptom not the cause of our fragile financial system. The action that will be most effective is coordinated efforts by G-20 powers to enact a global financial reform. Efforts being made in the U.S. will not solve the systemic risk that Greece has reminded us still exists.”
