Quando acabar o dinheiro fácil

LONDRES – A partida do Presidente da Reserva Federal dos EUA, Ben Bernanke, alimentou as especulações sobre quando e como a Reserva Federal e os outros bancos centrais irão reduzir as suas colossais aquisições de activos a longo prazo, também conhecidas como flexibilização quantitativa (QE quantitative easing). Os observadores aproveitam todos os novos dados económicos para prever a continuação da QE ou uma aceleração do seu declínio. Contudo, é necessário prestar mais atenção ao impacto que qualquer dos resultados terá nos diferentes agentes económicos.

É incontestável a dimensão dos programas de QE. Desde o início da crise financeira, a Reserva Federal, o Banco Central Europeu, o Banco de Inglaterra e o Banco do Japão recorreram à QE para injectar mais de 4 biliões de dólares de liquidez adicional nas suas economias. Quando estes programas terminarem, os governos, alguns mercados emergentes e algumas empresas poderão encontrar-se vulnerabilizados. É necessário que se preparem.

Um estudo realizado pelo McKinsey Global Institute indica que a redução das taxas de juro poupou aos governos dos EUA e da Europa cerca de 1,6 biliões de dólares entre 2007 e 2012. Esta benesse inesperada permitiu o aumento das despesas públicas e a diminuição da austeridade. Se as taxas de juro retrocedessem às cifras de 2007, os pagamentos de juros relativos à dívida pública poderiam sofrer um aumento de 20%, mantendo-se constantes outros factores.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
