Markets brace for Fed speech

Asian markets will be paying close attention to Federal Reserve Chairman Ben Bernanke's speech at the annual bankers' gathering at Jackson Hole, Wyoming later today.

The select, invitation-only meeting is closely watched by investors and economists. Given that Mr Bernanke announced a previous quantitative easing (QE) round of economic stimulus at the same event a couple of years ago, expectations are high he might do the same this time round.

The BBC's Michelle Fleury looks at the expectations running high in the markets that more QE might be on the way.
