I'm actually surprised at how much flak CV is taking. Most of the arguments about why this is bad news are dead wrong.
Unfortunately the inflation that already happened is not going to reverse. At this point the good news we're looking for is for inflation to go back to normal. Although there are some major caveats, most notably that the entire decrease in gas prices was wiped out by inflation in other categories, the idea that inflation M/M is it 0% is definitely good news.
Will inflation remain at 0% M/M for the next few months? Definitely not without a recession, but with transportation costs being a leader in inflation, fuel prices coming down to more manageable levels is excellent news and will likely lead to lower inflation in the coming months.
