To answer these questions, Investec Wealth & Investment spoke to British Conservative politician Philip Hammond, former Chancellor of the Exchequer from 2016-2019.
We also interviewed Victoria Clarke, an economist at Investec UK and former senior economic adviser to the UK Cabinet Office; and John Haynes, Chairman of Investec’s Global Investment Strategy Group (GISG) and Head of Research for Investec Wealth & Investment UK.
“Our view of the curve is that we will start to see a withdrawal of some of these restrictive measures within the next month to six weeks,” says Haynes. “Slowly you’ll start to see demand returning and a rapid move upwards in global growth to something close to 95% to 98% of the pre-crisis level, and then you’ll start to see a slower curve.”
Likening the global lockdown to shutting down an engine, Investec’s GISG believes that the massive fiscal and monetary policies being implemented while the engine is off – the petrol and the oil respectively – are sufficient to protect the “economic fabric” so that when the demand restrictions are lifted, it will be able to fire up successfully.

The future impact on retailers and global supply chains
World trading patterns will also be impacted after global supply chains have been found wanting during this crisis.
“Across the globe, people will be looking from a national security perspective at the way trade supply chains work and will be asking whether we need to mandate the building in of greater resilience," says Hammond.
“I can’t imagine, for example, that in the UK the public isn’t going to want to see some greater domestic capability to produce vital medical supplies and equipment in case there’s a further crisis of this nature. We already do this in the military sphere.”
A question mark also hangs over what impact the crisis will have on Brexit, says Clarke. “Will it make the EU and the UK more or less inclined to go for a freer, more integrated trading arrangement to drive the upturn? Or perhaps given that there’s more resilience or security in having more of a domestic process, this will reinforce the dynamic of onshoring?”

We have to accept that in the short term there’s going to be considerable pain. But this isn’t a war, the productive infrastructure of economies is not being destroyed. The shock to supply is temporary and it will bounce back.

Who will pay for the fiscal and monetary packages?
Post the crisis, US debt-to-GDP is estimated to rise to somewhere between 80% and 100% by the end of the decade. In the UK, it’s expected that public debt will also peak above 100% of GDP beyond 2025.
“Across economies globally we really are looking at some eye-watering fiscal numbers, and questions will be asked about what should be done to bring those debt trajectories back to something which most governments would feel more comfortable with,” says Clarke.
While the UK has worked hard to bring down its debt over the past 10 years, the extraordinary package of stimulus is going to need to be paid for, says Hammond.
“We will have to work out who’s going to bear the costs of this crisis and apportion it through borrowing to future generations, through taxation and spending restrictions for current generations, or through allowing more inflation.”

Unwinding intervention is easier said than done<br>
Globally, this will need coordination by the G20 and OECD, particularly when it comes to deciding what emergency trade measures are still legitimate and for how long they will be so post pandemic.
“In a crisis, it’s relatively easy to get people to play along. Once the crisis is over and we’re on the recovery slope, the temptations to game the system will come back very quickly,” says Hammond.
Within domestic economies, interventions like bailing out the airline industry, the poster child for climate change, will be tricky to get out of.
The geo-political landscape post crisis
The panel agreed that the global polarisation seen before Covid-19 will accelerate once the crisis is over and that the issue of China will need to be dealt with very carefully.China’s rise will continue unabated says Haynes, and post crisis, it will find its voice even more.
“Taking China on via a trade war to rebalance the global power balance is never going to work,” says Haynes, who believes the world’s second largest economy is seeking a “respectful relationship” with the US and all its trading partners.
“I read the Chinese as understanding their interests as being a force for stability. The justification of any dynasty is that they have the mandate of heaven – they provide stability for their people.”
“But if they get pushed too far by the way people decide to aggressively pursue a single interest slicing of the economic cake, then, a little like Saudi Arabia and Russia have decided to do a beggar-my-neighbour strategy in the oil markets, there is no guarantee that China wouldn’t do the same thing for trade markets, in order to make a point,” concludes Haynes.
Hammond agrees. “The key thing here is whether the Western powers are going to allow the international institutions that we have to evolve in a way that gives China a reasonable bite of the cherry. If we want China to be pro the status quo, then we have to make the status quo work for China.” However, if the Western powers continue to keep China out, then it will start to set up rival institutions, he says.

A vision for the future
“I suspect we will demonstrate resilience, and there will finally be a need to revisit the way we operate our economy and global supply chains to ensure that resilience in our trade structures is there in the future in a way that perhaps it hasn’t demonstrated over the last few weeks,” he concludes.
