Via Elliot Clarke at Westpac:
The minutes of a FOMC meeting typically hold little significance for the market. In this instance however, there is cause for a closer look. This is because the May minutes provide a clear assessment of the risks that the US currently faces, particularly with respect to inflation; financial conditions and foreign trade. The conclusion to draw is that an acceleration in the pace of interest rate hikes is not currently justified, nor is it expected.
Beginning with inflation, whereas the market has recently been concerned that inflation may be getting away from the FOMC (given annual CPI inflation at 2.5%yr and persistent strength in the oil price), the Committee is unperturbed.
