This week, the U.S. consumer price index for October showed a 6.2% increase from a year ago, the highest inflation rate since 1990, news that directly contributed to bitcoin’s mid-week surge to new all-time highs.

The freight price index is up 20% from a year ago. Those rising prices will themselves feed into U.S. consumer prices downstream. More importantly, it’s a direct manifestation of the shipping logjam that is associated with and contributing to supply chain interruptions. It’s worth watching for signs that the supply chain problem is either worsening or correcting itself.
