Trump versus Reagan – the global dimension

• ? Could the Trump era resemble the 1980s? ‘Reaganomics’ boosted world growth – but not necessarily in the ways people think – and not for emerging markets (EMs), a larger part of today's world economy. Growth then was also aided by factors such as declining interest rates, which are missing today, and we doubt that deregulation will lead to a productivity surge. US asset prices, meanwhile, were depressed in 1981, unlike now, so the big gains of the 1980s are unlikely to be repeated. EM assets should do better than back then, though.
• ? Optimistic observers – and to some extent, markets – have been drawing parallels between the policy mixes of the Trump and Reagan administrations, and talking up the prospects of stronger global growth. But while the US did support world growth in the 1980s, this was arguably more due to Keynesian' demand‐side policies than supply‐side ones: Reagan's record on supply‐side policies was mixed.
• ? The US is still an important driver of global activity, but markets may be too optimistic about the effect of Trump's policies on world growth. Any Trump fiscal stimulus will occur against a much less favourable background than that of the 1980s, when US growth also benefitted from a variety of factors missing now.
• ? It is also unclear whether Trump's administration will tolerate large expansions of the current account and fiscal deficits as the ‘price’ for more growth. And we are sceptical about the prospects of big gains from deregulation: US economic dynamism has waned, but the policies so far proposed in this area look potentially misdirected.
• ? Over the coming years asset market performance is unlikely to mirror that of the 1980s: valuations suggest less room for dollar appreciation and stock market gains this time around. But emerging market (EM) assets may do better – the soaring dollar and high US rates that hit EMs in the 1980s are unlikely to be repeated. And our analysis suggests even modestly better US growth will support commodity prices and EM growth.
