For Turkey's bankers and businesspeople it has been impossible to explain the high volatility in the exchange rate over the past few weeks. The fundamentals of the Turkish economy are solid and macroeconomic indicators fail to account for the recent slide in the Turkish lira, which dropped by more than 40% since the beginning of this year. These fluctuations are seen as manipulations on the Turkish lira and economy, as part of an economic war waged against Turkey by U.S. President Donald Trump. The U.S. dollar tumbled nearly 5% against the Turkish lira on Tuesday. European shares rebounded Tuesday as the Turkish currency firmed. The Central Bank introduced measures on the Turkish lira and the foreign exchange market (FX) liquidity management. The bank said it would provide all the liquidity needed by banks and closely monitor markets and prices, while raising collateral FX deposit limits for lenders' lira transactions from 7.2 billion euros ($8.2 billion) to 20 billion euros.
