New data out of Turkey has investors worried about a repeat of last year’s currency crisis.

According to a recent disclosure by the Central Bank of the Republic of Turkey (CBRT), foreign reserves dropped by 13 billion lira last week, adding to a monthly drop of 45.1 billion lira. In dollar terms, that’s equal to a roughly $10 billion dollar drop in March.

If this pace were to continue, Turkey would exhaust its entire remaining $25 billion stock of foreign reserves in less than three months.

The reserves are being spent to shore up the value of the lira, which is under sustained pressure from capital flight. Torrential capital outflows had already been well underway in early March (as the above numbers show), but they intensified recently after President Erdogan publically came out against President Trump’s declaration of support for recognizing the Golan Heights as Israeli territory – a move that many interpreted as harbinger of a new downturn in US-Turkey relations. The flight became so pronounced that Erdogan made the unprecedented move of banning foreign banks from accessing the lira needed to close out their positions, essentially halting short-term forex trades.

The Turkish authorities have indicated that the restrictions will remain in place until after the weekend. However, it’s likely that once the ban is lifted, there will be a race to the exits as previously fence-sitting investors try to clear out their holdings ahead of a future ban. Yet this is not Erdogan’s only problem: stock markets tanked after the ban announcement, with the benchmark ISE National 100 dropping over 5%, and overnight interest rates shot up to 1,200 percent – the highest level ever recorded.
