The UK's Transport Intelligence has announced that July's Logistics Confidence Index slid for a second straight month to 56.4, but remains still higher than in the same periods in 2013 and 2014, yet concerns linger over the outlook for next six months.

Indeed, demand appears to be easing off as the IATA director general Tony Tyler noted in an official release that business confidence is flat and export orders in decline. He further noted the uncertainty surrounding Greece's relationship with the Eurozone.

And while the six-month outlook may have had a negative effect on the index, the overall present situation is positive, gaining 1.8 points from June to 53.7. The gain was led by sea freight, up 3.9 points to 50.7, the first time it is above the neutral 50 since April.

IATA's latest air freight data for May indicates a slowing of tonnage growth. In fact, at 2.1 per cent year-on-year growth, it is the slowest this year.

This slowing growth may be why the current situation slipped 0.2 points. This slip was due to the Europe-Asia lanes. Europe to Asia fell 3.4 points to 55.6 while Asia to Europe fell 0.9 points to 51.9.

Meanwhile, the Europe-US lanes recorded positive present gains. Europe to US rose 2.2 points to 63.4 and after three months of contraction, the US to Europe lane gained 1.8 points to 50.7.

But the six-month outlook raises concerns as it fell 3.1 points. Worries over a Greek exit from the EU combined with ongoing sluggish economic growth appear to be among the reasons.

As a result, all trade lanes noted decreases with Europe to Asia and Asia to Europe each shedding 3.7 points to 59.5 and 62.7 respectively. Europe to US dropped 3.2 points to 61.3 and US to Europe slipped 1.2 points to 58.2.

Sea freight's expected situation was down by 2.2 points. All lanes shrunk with Europe to Asia decreasing the most at 4.4 points to 58.9. Asia to Europe declined 1.4 points to 61.4 and Europe to US and US to Europe each contracted 1.5 points to 61.5 and 54.1, respectively.
