U.S. Inflation Data Was Accidentally Released 30 Minutes Early

It doesn't matter much, but it does matter.

You can get a financial advantage if you get information early. (The comedy film Trading Places gives a remarkably accurate depiction.) If something drops early, those who notice get an advantage over those who didn't. That throws off the balance of calculations, hedges, etc. designed on the assumption that the data would come out at time T rather than T-:30.

It's not going to be a huge thing. Maybe some funds lost or gained a million dollars -- a tiny piece of their trillion-dollar capitalization. Maybe you personally could have lost a few dollars in your retirement account. Not enough to get angry about, but not going to thrill you, either.

So it's not a crisis. But they will make sure it doesn't happen again.

I guess it just reduces confidence in the people in charge. If they mess up something simple like the timing on a release then how well are they handling their fiddling with the economy which is complicated. Everyone makes mistakes, but some of theirs can have big consequences for everyone in the whole country.
