LONDON, July 17 (Reuters) - Wednesday's market drama on reports of an imminent ouster of Federal Reserve Chair Jerome Powell has calmed quickly, with President Donald Trump saying it was " highly unlikely" he would fire the central bank boss even as speculation continue to brew.

Speculation over the potential dismissal of Federal Reserve Chairman Jerome Powell by President Trump has sent shockwaves through financial markets, anticipating unprecedented chaos.

Investors are becoming more measured in their reaction to news about Trump's Washington policy, with Wednesday's whipsawing headlines over Federal Reserve Chair Jerome Powell triggering a reaction that fell short of what could happen if the Fed chair was indeed fired.

The rapidly intensifying multi-pronged efforts by Trump’s advisers to amplify and expand on Trump’s attacks are a good reason to rethink that indifference.
