Richmond Federal Reserve president Thomas Barkin said Friday he is comfortable with further interest rate increases if coming data does not show that weakening demand for goods and services is feeding through to slower inflation. "I am still looking to be convinced of the plausible story that slowing demand returns inflation relatively quickly" to the 2% target, Barkin said in comments prepared for delivery to the Maryland Government Finance Officer Association. The Fed this week held the policy interest rate steady in a range between 5% and 5.25%, but new policymaker projections showed Fed officials feel rate may need to rise at least another half point by the end of the year.
