Current account deficit and foreign-currency debt
Previous economic growth had been led by fiscal and monetary stimulus to the construction industry,
resulting in a huge backlog of unsold new houses,
and unprofitable grand projects like the Yavuz Sultan Selim Bridge
A longstanding characteristic of Turkey's economy is a low savings rate. Since Recep Tayyip Erdoğan assumed control of the government, Turkey has been running huge and growing current account deficits, $33.1 billion in 2016 and $47.3 billion in 2017, climbing to US$7.1 billion in the month of January 2018 with the rolling 12-month deficit rising to $51.6 billion, one of the largest current account deficits in the world. The economy has relied on capital inflows to fund private-sector excess, with Turkey's banks and big firms borrowing heavily, often in foreign currencies. Under these conditions, Turkey must find approximately $200 billion a year to fund its wide current account deficit and maturing debt, while being always at risk of inflows drying up; the state has gross foreign currency reserves of just $85 billion. The economic policy underlying these trends had increasingly been micro-managed by Erdoğan since the election of his AK Party in 2002, and strongly so since 2008, with a focus on the construction industry, state-awarded contracts and stimulus measures. Although, research and development expenditure of the country (% of GDP) and the government expenditure on education (% of GDP) are nearly doubled during AK Party governments, the desired outcomes could not been achieved The motive for these policies have been described as Erdoğan losing faith in Western-style capitalism since the 2008 financial crisis by the secretary general of the main Turkish business association, TUSIAD.
Investment inflows had already been declining in the period leading up to the crisis, owing to Erdoğan instigating political disagreements with countries that were major sources of such inflows (such as Germany, France, and the Netherlands). Following the 2016 coup attempt, the government seized the assets of those it considered involved, even if their ties to the coup were attenuated. Erdoğan has not taken seriously concerns that foreign companies investing in Turkey might be deterred by the country's political instability. Other factors include worries about the decreasing value of lira (TRY) which threatens to eat into investors' profit margins. Investment inflows have also declined because Erdoğan's increasing authoritarianism has quelled free and factual reporting by financial analysts in Turkey. Between January and May 2017, foreign portfolio investors funded $13.2 billion of Turkey's $17.5 billion current account deficit, according to the latest available data. During the same period this year they plugged just $763 million of a swollen $27.3 billion deficit.
By the end of 2017, the corporate foreign-currency debt in Turkey had more than doubled since 2009, up to $214 billion after netting against their foreign-exchange assets. Turkey's gross external debt, both public and private, stood at $453.2 billion at the end of 2017. As of March 2018, $181.8 billion of external debt, public and private, was due to mature within a year. Non-resident holdings of domestic shares stood at $53.3 billion in early March and at $39.6 billion in mid-May, and non-resident holdings of domestic government bonds stood at $32.0 billion in early March and at $24.7 billion in mid-May. Overall non-residents’ ownership of Turkish equities, government bonds and corporate debt has plummeted from a high of $92 billion in August 2017 to just $53 billion as of July 13, 2018.
