Shipping analysts spend plenty of time assessing the merits of the capacity in the fleet and the volume of seaborne trade. However, there’s another important aspect of the shipping industry which also tells us something important about market activity. Ports and port calls are the joints that hold the trade network together, the origins and destinations of cargoes and the key locations for the ships that carry them.

The vast majority of the world’s trade in goods is moved by sea, and it has long been recognised how shipping is a critical element of the global economy, providing the connection between producers and consumers all over the planet. However, what is less frequently mentioned is the tremendous ‘value for money’ with which it does so; this is clearly worth a closer look…

Bargain Of The Century?

One US dollar doesn’t get you much in today’s world. On the basis of latest prices it would buy 0.025 grams of gold or 2% of a barrel of crude oil. Based on Walmart’s latest online pricing it would buy about half a litre of milk. That’s not a lot whichever way you look at it, in a world economy that is 75 trillion dollars large. But in shipping one dollar still gets you something very substantial. One way of looking at this is to take the movement of cargo in tonne-mile terms and divide it by the estimated value of the fleet. Here, to try to do this in like-for-like terms, the calculation includes crude and oil products, dry bulk, container and gas trade, and the ships that primarily carry those cargoes. On this basis, one dollar of ‘world fleet value’ at the start of May 2017 would have bought 110 tonne-miles in a year, based on 2017 trade projections. What an amazing bargain! One tonne of cargo moved more than 100 miles, per year, all for one little greenback!

What’s In A Number?

What drives this number? Well the essence of the value of course lies in the huge economies of scale generated by moving cargo by sea in vast quantities at one time over significant distances. The average haul of one tonne in the scope of the cargoes listed above is estimated at 5,016 miles and the average ship size at 58,706 dwt. Of course the amount of tonne-miles per dollar can vary over time, depending on changes in asset market conditions, the underlying cost and complexity of building ships and vessel productivity, speed and utilisation (rates of fleet and trade growth aren’t perfectly aligned most of the time). Across sectors the statistics can vary significantly too.

Buy In Bulk

One dollar of bulkcarrier and oil tanker tonnage accounts for 154 and 101 tonne-miles of trade per year respectively. For more complex, expensive ships the figure is lower: 20 for gas carriers. For boxships, despite their higher speed, the figure stands at 114. Vessel size (economies of scale in building) and cargo density (this analysis is in tonnes) play a role too in these relative statistics (which also don’t always capture the full range of cargo carried by each ship type).

Value For All Time

Nevertheless, whatever the precise numbers and changes over time, 110 tonne miles of trade each year for one dollar of asset expenditure just sounds like mighty good value at a time when a dollar doesn’t go very far. This underpins shipping’s ability to carry an estimated 84% of the world’s trade in tonnes and act as the glue holding the globalised economy together. Shipping’s famous volatility retains the ability to make and lose fortunes for asset players but the underlying economic contribution of each dollar invested may just be one of the greatest bargains of all time. Have a nice day.

Shipping plays a major role in the world’s industries, facilitating the transport of large volumes of raw and processed materials. However, the maritime sector forms a much more important part of the global supply chain for some commodities and industries than others. Comparing world seaborne trade in a range of cargoes to global production helps to make this abundantly clear.

Still In The Limelight

Looking at a range of cargo types (see graph), less than 50% of global production of each was shipped by sea in 2015, with a significant share of output consumed domestically. However, seaborne transport still accounts for a sizeable proportion of many of these cargoes, and a wide range of factors influence the level of dependence on shipping of each.

Compelling Cues

One obvious driver is the location of production and consumption. Crude oil is the commodity most reliant on shipping, with some 46% of crude output last year exported by sea, with oil output concentrated in a relatively small number of countries. Similarly, around 41% of global iron ore production was shipped last year, with limited domestic demand in key producers Australia and Brazil. Absolute and relative regional productivity also has an influence. Just 15% of coal output was shipped in 2015, with half of the 6.5bt of coal produced globally last year output in China, nearly all of which was consumed domestically. Still, China was the second largest coal importer in 2015, with regional coal price arbitrages driving trade.

Another key factor is the availability and efficiency of other transport modes. Twice as much natural gas is exported via pipeline than in a liquefied state by sea, with just 9% of natural gas output in 2015 shipped as LNG. Meanwhile, the level of processing of materials also has an impact. Oil and steel products are less reliant on shipping than crude oil and iron ore, with refineries and steel mills often built to service domestic demand.

Raising The Drama

However, the growth of ‘refining hubs’ has raised the share of refinery throughput shipped by almost 10 percentage points since 2000. This kind of trend is an important driver of shipping demand. The share of output of the featured commodities shipped rose from an estimated 22% in 2000 to 26% in 2015, generating c.720mt of extra trade. This equates to an additional 1% p.a. of trade growth, boosting trade expansion to a CAGR of 3.7% in 2000-15. Trade in some cargoes is more sensitive to shifts in the share of output shipped than others, but across the featured cargoes, a further change of 0.5% in the share of output shipped could create another 130mt of trade, 2% of current seaborne volumes.

No Sign Of Stage Fright

So, while trade in even the cargo most reliant on shipping accounts for less than half of global output, the world economy today is still dependent on the seaborne transport of 11bt of all cargo types. Overall growth in production and the distance to consumers are also clearly important demand drivers for shipping, but for the world’s industries there’s no denying the main part that shipping still plays in the supply of raw materials. Have a nice day!
