Investors better buckle up. It's going to be a bumpy ride.
U.S. stock futures were sharply lower Monday after a bailout agreement reached over the weekend in Cyprus sparked outrage in the tiny nation.
The European Union unveiled a €10 billion plan early Saturday to rescue Cyprus' outsized banking sector and avoid a default. Though the bailout is relatively small, the EU has required a one-time tax of 6.75% on bank deposits of less than €100,000 and 9.9% for those over that amount.
Cypriots rushed to ATMs as the country tried to win parliamentary support for the plan. The worry is that investors and depositors in other financially weak European nations might fear similar bailout provisions in the future, which has the potential to destabilize global financial markets.
Early Monday, Cypriot leaders said a vote on the plan has been delayed until Tuesday.
"For now, one would suspect that markets are calm enough that the contagion will be limited, but such a move could easily amplify any future crisis in Europe as the specter of deposit losses will now be on the table whatever politicians say in advance," wrote Deutsche Bank analyst Jim Reid, in a report to investors.
Also, Cyprus isn't just some isolated island nation. The impact of a high tax would be immediately felt by investors in other countries.
Russian investors, in particular, have a lot of money tied up in the country's banks.
"Cypriot banks are widely thought to hold large sums of legally questionable funds - a true tax haven - especially by Russian standards," said Marc Chandler, analyst for Brown Brothers Harriman. "Estimates suggest more than half the deposits in Cyprus belong to non-residents."
