Global economy robust to higher oil, but EM vulnerable

▀ We do not envisage major central banks being pricked into deflationary action by the oil spike as there are limited concerns over a wage‐price spiral. But further rises — say to $100pb — would sour the global economy's ‘Goldilocks’ period. Vulnerable EM are the biggest concern; for some the impact is relatively large and could pile pressure on already‐strained domestic policies . ▀ A comparison with historical precedents is generally consoling. First, the price rise of 60% in the last year — though big — is only the sixth largest since 1973. Second, oil‐related global slowdowns have usually been associated with central bank hikes, which are less likely now than in past periods when inflation was less well anchored. ▀ Global implications: our baseline forecast of $80bp in H2 2018 may prompt a modest rise in non‐energy inflation and wages, and slightly weaker GDP growth. But we anticipate limited monetary policy responses. Concerns about the negative impact on activity are likely to trump fears of second‐round inflation effects. ▀ Model simulations: souring Goldilocks' porridge. Our $100pb oil simulations reveal a peak impact in 2020, knocking 0.7% off the level of global GDP. Inflation rises 1.2pp above our baseline by 2019. ▀ The recent association between strong oil and a strong dollar is unusual, but is probably not reflective of a fundamental change in the usual historic relationship (strong oil‐weak dollar). ▀ Simulations suggest EM oil importers endure the biggest hits via a (i) sharp terms of trade reversal; (ii) dollar strength; (iii) capital flows reversals; and (iv) recent reductions of oil price subsidies leaving consumers vulnerable to price increases. The most affected include already‐vulnerable economies Greece, Argentina and Turkey, as well as EM heavyweights China and India.
