This deviation does not worry me that much, in part because I expect inflation to move back to target over the medium term, in part as some unusually low readings in early 2019 pass out of the data. Already, various trimmed price indexes are running much closer to 2 percent.
FYROM has no other sea outlet, but Thessaloniki also is closer to Sofia than the Bulgarian ports in the Black Sea, and the same applies for large regions in South-East Romania, South Serbia etc. Companies established in these regions will find it more convenient to use Thessaloniki as a trading port than other sea outlets.
