According to Ekathimerini, Greek-owned shipping companies invested almost 10 BUSD in 2017. To repeat: that is ten billion US dollars! That amount was split roughly 50:50 between the purchase of used and new vessels. It should be noted that these are official records only. Not included would be any private deals.
By all possible measures, Greek shipowners are the leaders of the pack world-wide. And to put things into perspective: Greek shipowners last year spent an amount on new investments which is almost twice the amount which the state spent on the service of its debt!
It is quite amazing that a nation which can produce world leaders in a highly competitive global industry is unable to produce domestic leaders which can run the country successfully.
