Wird der Markt zur Geisel der Hacker?

NEW YORK – Nie zuvor in der Geschichte der schriftlichen Kommunikation waren 140 Zeichen so einflussreich wie heute. Nachdem es einer Gruppe namens „Syrian Electronic Army“ (Syrische Elektronische Armee, SEA) vor zwei Wochen gelungen war, sich Zugriff auf das Twitter-Konto der Nachrichtenagentur Associated Press (@AP) zu verschaffen, verbreiteten die Hacker eine Falschmeldung über Twitter, in der sie zwei Explosionen im Weißen Haus und eine Verletzung von Präsident Barack Obama verkündeten. Innerhalb von Sekunden gingen die Kurse an den US-Finanzmärkten auf Talfahrt.

Wenige Minuten später wurde die Meldung auf Twitter als falsch widerlegt. Reporter im Weißen Haus twitterten, dass sie keine Explosion gespürt hätten, AP-Reporter dementierten die Falschmeldung und auf dem Twitter-Konto von AP wurde bekanntgegeben, dass @AP gehackt wurde. Der Pressesprecher des Weißen Hauses, Jay Carney, bestätigte, dass Präsident Obama wohlauf ist. Die Börsenkurse kehrten auf ihr Niveau vor der Falschmeldung zurück.

Die Twitter-Falschmeldung auf @AP steht für ein unvermeidliches Systemrisiko, das aus dem Zusammenspiel von hochgradig integrierten Finanzmärkten und einer zunehmend demokratisierten Nachrichtenverbreitung erwächst. Der Anreiz für böswillige Dritte, derartige Falschmeldungen zu verbreiten ist hoch, und wir sollten davon ausgehen, dass die Zahl der Vorfälle zunehmen wird.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
