On Tuesday, the Port of Wuhan, a vital cog in China’s heavy industry supply chains, reopened for business after more than two months of being locked-down at the centre of China’s initial coronavirus outbreak. In the same week, Ethiopia closed its land borders, Myanmar cancelled all commercial flights and South Africa restricted cargo movements to non-essential goods, joining the United States, Canada, Mexico and most of Europe in deploying draconian containment strategies aimed at stopping the virus’ spread. It was a case of one door opening and 50 slamming shut. This winding down of international connectivity is set to paralyse global trade, the effects of which can already be viewed through a number of early indicators , and advance governmental statistics. Air freight prices have spiked on routes out of China, by more than 200 per cent to destinations in Southeast Asia as factories desperately try to source components amid fears of further lockdowns, but also by more than 100 per cent to Europe and the United States, according to TAC Index, which monitors air freight rates. With barely any airlines flying out of China any more, it is more expensive to book cargo space and this will continue as the number of carriers dwindle and trade collapses along with it. But with much of the valuable space on these planes taken by vital medical equipment, there is vanishing room for anything else. In another sign of the hit to come to air cargo – which transports more than US$6 trillion worth of goods per year, accounting for 35 per cent of global trade by value, according to the International Air Transport Association – Chinese airlines were told this week to maintain only one route to any specific country, with no more than one flight a week. An estimated half of air freight – which is typically made up of high value or emergency products – travels in the belly of passenger jets. The dwindling number of flights presents another body blow to global trade, which fell by 1.2 per cent in January, according to the respected World Trade Monitor, conducted by the official statistics bureau of the Netherlands. Gaps in the air freight network forced New England Patriots owner Robert Kraft to send his private jet to China this week to pick up a million masks and other medical equipment. “When you think of how much trade travels in passenger planes, and 90 per cent of those are now grounded out of China, that capacity is now completely gone,” said Stefan Holmqvist, managing director of Norman Logistics in Hong Kong. “It is left with the freighters, but with demand for medical equipment so high there is limited space.” The picture on the seas may look calmer, but extreme volatility is lurking beneath the surface. Dan Brutlag, head of trading signal and data products at Cargometrics, a technology company tracking every ship on the world’s oceans, said that “tonnage for both Chinese exports and imports have recovered compared to levels we saw in February, but remains slightly below levels we would expect to see this time of year”. But Brutlag and everyone else in the business is looking for the iceberg dead ahead. Most of the cargo on ships currently at sea has already been paid for, meaning it measures previous demand. When these arrive at the port, will there be the requisite manpower to unload them? Then, where do they go? “We are expecting a tidal wave of cargo from China in the next few weeks – with little open and nowhere to put it – we are going to wind up with a big infrastructure mess at the ports and distribution centres,” said Steve Ferreira, CEO at Ocean Audit, another tracking firm. “It’s all doom and gloom. Many of my customers are doing home delivery or drive up sales – but that is nothing compared to the normal brick and mortar pace.” New demand for shipped goods is thin. “We are seeing a lot of cancelled sailings out of China for the US and Europe, at very short notice,” said Holmqvist. “It usually comes quite far in advance, but I would say now at short notice 30 per cent of these are blank sailings.” We are seeing a lot of cancelled sailings out of China for the US and Europe, at very short notice Stefan Holmqvist A report by shipping consultancy Dewry this week confirmed that “void sailing notices from carriers for April are coming in thick and fast”, while bunker prices – fuel for shipping – have fallen by more than 90 per cent for some forms of fuel. Container ships are running with almost 10 per cent slack capacity, a figure which has rocketed up in recent weeks. It is quite easy to see why: as the world shuts down, people are buying fewer things, well illustrated by various government surveys this week. Manufacturers in India saw a record decline in export orders, Mexico too. For those in the US, Canada and Italy, meanwhile, it was the worst month for orders since the global financial crisis more than a decade ago. Factory owners in China are also seeing the hit, with cancelled orders and delayed shipments becoming a chronic problem, which will only get worse as the world heads deeper into the biggest globalised crisis since World War II.
