Bernanke incontra la stampa

CAMBRIDGE – Durante la recente conferenza stampa della Federal Reserve americana, la prima che sia mai rilasciata pubblicamente, il presidente Ben Bernanke ha difeso con vigore il tanto criticato piano di acquisto dei titoli di stato americani, altrimenti detto “quantitative easing”. Le sue giustificazioni saranno state persuasive?

La maggior parte degli economisti lo giudica un colpo da maestro. Tuttavia, il fatto che il dollaro abbia continuato a scivolare e i prezzi dell’oro non abbiano cessato la propria ascesa suggerisce un notevole scetticismo da parte dei mercati. Uno degli aspetti più pesanti del sistema bancario centrale è che gli investitori spesso recepiscono un messaggio sostanzialmente diverso da quello che intende trasmettere la banca centrale.

La Fed, ovviamente, è stata forzata a passare al “QE”, come lo chiamano i trader, dal momento che lo strumento normalmente utilizzato per ritoccare inflazione e crescita, ossia il tasso di interesse overnight, è già a zero. Eppure la crescita economica americana resta stagnante, accompagnata da una disoccupazione ostinatamente elevata. Il QE è stato incolpato di qualsiasi cosa, dalle bolle finanziarie alle rivolte per il carovita all’impetigine. Chiunque ha attaccato violentemente questa manovra, dai ministri delle finanze esteri ai fumettisti satirici (si veda a tal proposito il video “quantitative easing explained”) fino a Sarah Palin.

    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.
