The Dow Jones Industrial Average fell over 150 points as geopolitical issues in Turkey ravaged the U.S. capital markets, while the Turkish lira continued to devalue as U.S. President Donald Trump ratcheted up tariffs on aluminum and steel amid growing dissention between the two countries.

“This is a classic, instinctive reaction in the market,” said Quincy Krosby, chief market strategist at Prudential Financial. “Stocks are down while gold and Treasurys are getting a bid.”

“The currency issue in emerging markets, in Turkey, is nothing new. This is just exacerbated,” Krosby added. “Historically, you’ve seen central banks act to ease these types of situations. The goal for them is to minimize collateral damage.”

The iShares MSCI Turkey ETF (NasdaqGM: TUR) tumbled 15.88% as of 10:45 p.m. ET. The ETF has been battered year-to-date–down 33.01% based on Yahoo! Finance performance numbers.

Other indexes were down in the early trading session with the Nasdaq Composite falling over 40 points and the S&P 500 was down just under 20 points. Earlier this week, the S&P 500 was just 0.8 percent away from reaching an all-time high of 2,872.87, which was established on Jan. 26. Additionally, the Nasdaq was also within 1 percent of a record high and the Dow was over 4.2 percent away from reaching its own all-time high.

Through the end of last week, the S&P 500 was up 24 percent on earnings in the second quarter on a year-over-year basis. However, ongoing trade wars between the U.S. and China have disrupted the path to new highs.

Now, Turkey is in the forefront with Turkish President Recep Tayyip Erdogan calling upon citizens to convert all foreign currency to Turkish lira.

“The Turkish lira is plummeting for a variety of reasons most notably the central bank’s refusal to raise interest rates to support it as well as a recent ramp up in U.S. sanctions,” said Alec Young, managing director of global markets research at FTSE Russell. “Currency weakness is fueling inflation and making it more expensive for Turkey to repay its large foreign currency denominated debt.”
