Here comes inflation ...

The consumer price index for September is set for release at the bottom of the hour.

Economists estimate that the reading on inflation fell 0.2% month-on-month, and -0.1% year-on-year.

Excluding food and energy, "core" CPI is expected at 0.1% month-on-month, and 1.8% year-on-year, according to Bloomberg.

Here's the preview to clients from UBS' Sam Coffin: "The acceleration to a 2.0% annual rate so far this year from 2014's 1.6% y/y reflects both rents and nonshelter components. Apparel has been a particular contributor despite dollar strength, underlying the importance of domestic demand trends. Used car prices have also contributed, swinging from falling to rising. Airfares give some downside risk to our forecast, depending on the passthrough from energy prices to ticket prices."

We'll be back with the latest once the data cross.
