The Fed’s Risk to Emerging Economies

The US Federal Reserve has finally, after almost a decade of steadfast inaction, set off down the path of interest-rate normalization. But other central banks' reluctance to follow the Fed’s lead implies a coming period of monetary-policy divergence, with uncertain consequences for the global economy.

MILAN – The US Federal Reserve has finally, after almost a decade of steadfast adherence to very low interest rates, hiked its federal funds rate – the rate from which all other interest rates in the economy take their cue – by 25 basis points. That brings the new rate up to a still-minimal 0.5%, and Fed Chair Janet Yellen has wisely promised that any future increases will be gradual. Given the state of the US economy – real growth of 2%, a tightening labor market, and little evidence of inflation rising toward the Fed’s 2% target – I view the rate rise as a reasonable and cautious first step toward normality (defined as a better balance between borrowers and lenders).

However, other central banks, particularly in economies where the output gap is larger than in the United States, will not be keen to follow the Fed’s lead. That implies a coming period of monetary-policy divergence, with uncertain consequences for the global economy.

On the face of it, a tiny change in the US rate should not trigger dramatic shifts in global capital flows. But, as US monetary policy follows the path of interest-rate normalization, there could well be knock-on effects, both economic and financial, especially in the form of currency volatility and destabilizing outflows from emerging economies.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
