The dollar index fell to a one-week low and finished down 0.48% on Wednesday after the Federal Open Market Committee kept the fed funds target range unchanged at 3.50% to 3.75% in a 9-3 vote, with Cleveland Fed President Beth Hammack, Minneapolis Fed President Neel Kashkari, and Dallas Fed President Lorie Logan dissenting in favor of a quarter-point rate hike. The post-meeting statement noted that economic activity is expanding at a solid pace despite elevated uncertainty tied to the Middle East conflict, while inflation remains elevated partly due to supply shocks in energy. Fed Chair Warsh said the economy is showing impressive resilience and policymakers will not hesitate to act if inflation stays high. The dollar had briefly gained earlier in the session after crude oil surged more than 6% when President Trump said the US will hit Iran hard following an Iranian attack on a US base in Jordan, but those gains reversed after the rate decision. Markets are now pricing a 59% probability of a 25-basis-point hike at the next FOMC meeting on September 15-16.
