The embattled Turkish lira tumbled over 16 per cent to new record lows against the dollar on Friday as strains with the United States intensified, but President Recep Tayyip Erdogan defiantly proclaimed Turkey would emerge victorious in an "economic war".
Compounding the lira's agony, President Donald Trump said he had doubled steel and aluminium tariffs on Turkey, noting that relations between the NATO allies were "not very good".
The lira's plunge is one of the most serious economic crises that Erdogan has faced since coming to power in 2003 in the wake of a financial crisis in 2001 that brought the economy to near meltdown.
The currency turbulence coincides with the most bitter dispute with the United States since the 1974 Turkish invasion of Cyprus, which so far shows no sign of abating.
