Turkey and US bonds

November 2014 ... Turkey's investments in US bonds amounted to about $ 80 billion

January 2018 ... Turkey's investments in US bonds amounted to about $ 49.6 billion

June 2018 ... Turkey's investments in US bonds amounted to about $ 29.6 billion

February 2019 ... Turkey's investments in US treasury bonds and bonds amounted to less than $ 3.2 billion at the lowest level in the past 12 years

March 31 ... Turkish local elections

The questions remain ...

What is the fundamental reason for this sharp decline ?! And is the Turkish lira approaching a new decline with the upcoming local elections and also with the straining of US-Turkish relations because of the rapprochement between Russia and Turkey militarily and economically? !!!
