The Fed's newfound focus on data is bad news for the sliding dollar

• The US dollar has slipped against other currencies this year.
• Its losing streak could carry on with the Fed taking a "data-dependent approach" to interest rates.
• The greenback would become less attractive to foreign investors if the central bank stopped tightening.

The dollar is one of the few assets that's gone down, rather than up this year – and analysts are warning that there could be bleaker times ahead for the greenback now that the Federal Reserve looks set to wind down its interest-rate hiking campaign.
