Two series that should have nothing to do with each other
Surprise me
GLOVIZ picked KRW per EUR from European Central Bank and Henry Hub natural gas price from FRED, Federal Reserve Bank of St. Louis, paired them on time, and found a correlation of 0.834 over 59 matched observations. Two different institutions, two different measurement programmes, no shared mechanism. That is the point: with a thousand series, coincidences are cheap.
