Trump is wrong. Trade wars are not easy to win, even non-players end up as losers
- The economic fallout of Trump’s trade and currency wars can’t be rolled back with the throw of a switch
- A global rescue can be financed only by central banks undertaking even bigger purchases of government debt than they have done already

If this sounds overly pessimistic, try counting the grounds for optimism that the global economy can exit safely from Trump’s trade and currency wars. Then compare the result with the reasons for fearing a stall, as speed and altitude meters continue to register declines, and see which scores highest.
It is not just indicators like the growth of the world’s biggest economies (the US, China, Japan and Germany) that are falling. A range of other instruments, registering everything from the rising value of dollar debt to outflows of funds from emerging markets, are signalling altitude loss.
Yet, it does not require a gargantuan intellect to compute the risks in the global economy and to see that it is already in stall mode. The onus now is on those who believe recession can be avoided to justify their optimism, rather than on “pessimists” to prove their case.
