Une année de défauts souverains ?

MIAMI – Quand il s'agit de dette souveraine, le terme « défaut » est souvent mal compris. Cela n'implique presque jamais le rejet complet et permanent de l'encours total de la dette. En effet, même certaines obligations de l'époque tsariste, les fameux emprunts russes, ont finalement (mais parfois seulement en partie) été remboursés après la Révolution de 1917. En revanche, un non-paiement (un « défaut », selon les agences de notation, quand il implique des créanciers privés), oriente généralement la conversation vers la restructuration de la dette, ce qui peut impliquer des échéances prorogées, des réductions de coupon-paiement, des délais de grâce ou des réductions de la valeur nominale (en anglais « haircut », pour désigner une décote par rapport à la valeur marchande).

Si l'on peut se fier aux enseignements de l'histoire, des conversations de ce genre devraient être monnaie courante en 2016.

Comme tant d'autres caractéristiques de l'économie mondiale, l'accumulation de dette et de défaut a tendance à se produire par cycles. Depuis 1800, l'économie mondiale a subi plusieurs de ces cycles, la part des pays indépendants subissant une restructuration au cours d'une année donnée oscillant entre zéro et 50% (cf. schéma). Bien que des accalmies d'une à deux décennies sur les défauts soient fréquentes, néanmoins chaque temps calme est invariablement suivi d'une nouvelle vague de défauts de paiement.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
