NEW YORK/LONDON, Aug 10 (Reuters) - A plunge in the Turkish lira rocked global equities and emerging markets on Friday and fear of further fallout sent investors scurrying for safety in assets like the yen and U.S. government bonds.
European shares and a gauge of global equity markets closed down more than 1 percent, while Wall Street also fell, though not as much. Germany's DAX index .GDAXI slid 2 percent.
The lira fell as much as 18 percent against the dollar in its worst day since Turkey's financial crisis of 2001. The plunge followed a deepening rift with the United States, worries about its own economy and lack of action from policymakers. Tayyip Erdogan told Turks to swap gold and dollars into lira as the currency tumbled after President Donald Trump doubled U.S. tariffs on metals imports from Turkey. later warned the United States that sanctions and pressure would only serve to harm ties between the two NATO allies, adding Ankara would continue to retaliate as necessary against U.S. tariffs. lira has fallen more than 40 percent this year, fanning worries about a full-blown economic crisis.
Bank shares across Europe fell and the euro slipped to its lowest since July 2017 as the Financial Times quoted sources as saying the European Central Bank was concerned about European lenders' exposure to Turkey. The country is not a member of the European Union but is economically linked to it. dollar rose as exposure to Turkey could impact European banks and spark a domino effect as people begin to pull out of those banks and into U.S. assets, said Gregan Anderson, macroeconomic strategist at brokerage Bulltick LLC.
The flare-up in tensions has made it difficult for global investors to justify remaining in Europe and is negative for emerging markets, he said.
Policy errors created the current situation, with Turkey's central bank decision not to raise rates in their last meeting a key driver, said Charlie Wilson, an emerging markets-focused portfolio manager at Thornburg Investment Management in Santa Fe, New Mexico.
"The lira has been weakening since and it's coming to a head today," Wilson said, adding the downward spiral will continue if Turkey insists on a soft landing.
"The only way to correct these policy mistakes is to really make some concrete changes on the fiscal and monetary side."
Shares in France's BNP Paribas BNPP.PA , Italy's UniCredit CRDI.MI and Spain's BBVA BBVA.MC , the banks seen as most exposed to Turkey, fell 3 percent or more. index of regional banking shares .SX7E closed down 3.2 percent while the pan-European STOXX 600 index .STOXX fell 1.07 percent.

Adding to emerging market currency woes was the Russian ruble, RUBUTSTN=MCX which weakened to 67.6825 to the dollar. Overnight it had retreated to its lowest since November 2016 on threats of new U.S. sanctions, weakening beyond the psychologically important 65-per-dollar threshold. prices rose more than 1 percent as U.S. sanctions against Iran looked set to tighten supply, but futures remained lower for the week as investors worried that global trade disputes could slow economic growth and hurt demand for energy.
