Disliked{quote} At a high-level, here's how I'm looking at it... Hypothetically, let's pretend the UK Consumer Price Index was at 100 for all of year 2000. Then in January 2001, there was an energy embargo that caused energy prices to soar. That in turn drove CPI from 100 to 110 in January representing a 10% increase in a single month. After that point, CPI remains at 110 for the next year. The M/M gain for February, March, April, etc. would be 0.0%, but the Y/Y gain is still 10% since, despite not actually rising from the prior month, it's still 10% higher...Ignored
