* The euro zone's blue-chip Euro STOXX 50 <.STOXX50E> index was down 2.8 percent in morning trade, retracing more than 50 percent of its recent recovery rally, with Franco-Belgian bank Dexia plummeting 24 percent to a record low.

* Euro zone finance ministers are reviewing the size of the private sector's involvement in a second international bailout package for Greece, a move that could undermine the aid program and hasten the threat of a Greek default.

* On the economic front, investors awaited August factory orders.

* The dollar was supported near a 9-month high against a basket of currencies on Tuesday with the market gripped by fear the debt crisis in Europe could unleash substantial damage on the global economy.

* U.S. stocks dropped to a 13-month low in heavy volume on Monday as investors dumped banking shares on fears Greece's debt woes could spark a full-blown banking crisis in Europe.
