Before the Fed decision the dollar index was flat amid unusually high outcome
uncertainty. Goldman Sachs economists expect the Fed to hold today but
anticipate at least one dissenting vote for a hike, noting war-driven
energy-price volatility clouds the outlook. Market pricing assigns roughly a 30%
chance of a rate increase today; CME data shows investors have priced in a
September hike. Goldman says if the Fed holds, FX markets will focus on how much
previously priced-in tightening shifts to later meetings.
