Storm Ciara, the winter storm that battered the UK with 80mph-plus winds and flooded vast areas after hours of torrential rain, had a plus side, apparently. It was behind what is being hailed as the fastest subsonic flight between New York and London.

A British Airways Boeing 747-436 flying from New York to London was propelled by tailwinds which saw it travelling at 825 mph as it rode a jet stream. Such was the force of that tailwind that it landed at Heathrow Airport 80 minutes ahead of schedule, having made the journey in a record four hours and 56 minutes.

We hear about tailwinds and headwinds, figurative if not literal ones, a lot when it comes to the world’s stock markets. Yesterday morning’s record-breaking transatlantic flight is a very real-world example of just how powerful a force tailwinds can be.

There was also a very real-world reminder of the impact that headwinds, which blow against the direction of travel, can have as well. Flights travelling at the same time, but in the opposite direction, from London to New York, took more than two and a half hours more than usual to reach their destination.

When it comes to figurative headwinds; the sort that keep central bankers, economists and market watchers awake at night, there are certainly more than enough to contend with at the moment.

From coronavirus to trade wars and let’s not forget Brexit or US president Donald Trump’s impeachment, the backdraft from a number of headwinds right now, is being felt in various corners of the world.

That though is not to say headwinds have to be entirely negative. As the British Airways jet has shown, sometimes a storm can produce some unexpectedly positive results.

Take the latest econo-political headwinds, which have all been weathered by the markets pretty well so far. The unsuccessful impeachment of Donald Trump has seen markets rise, not fall. In fact, much as they did when Bill Clinton was impeached in the 1990s. The US stock market continued to climb, even as the sordid details that emerged surrounding the then-president’s affair and subsequent lies about the affair, emerged.

Market bets that Trump would be impeached, but would not be removed from office, paid off. Instead, investors are looking ahead to the second half of 2020, when the US presidential election could be a source of volatility.

Even the coronovirus epidemic was being brushed off by markets last week, despite the death toll and the global spread growing.

One headwind that could have a negative impact though is the continued grounding of the 737 Max jet. With the planes - and their production - stalled until they get clearance following two fatal crashes, that is a problem that is not going away and in fact, keeps on getting worse.

Now, almost two months into the new year, there is no sign that the jets will be back in service any time soon, and that is very bad news.

And not just for the US economy, but also the airlines and travel companies, like Anglo-German TUI, the world’s biggest tour operator which are now racing to find secure seats on other airlines to fly holidaymakers overseas during the upcoming peak summer holiday season.

Boeing, which makes the 737 Max is the US’s largest exporter and a crucial part of America's manufacturing sector. With US factories already strained by the trade fight between the United States and China - and now the impact of the coronavirus - the ongoing Boeing stoppage can only add more pain.
