Why Narrow Money (M1) matters for JPY
Rapid M1 growth can signal future inflationary pressures via the quantity theory of money. Conversely, shrinking M1 may indicate tightening monetary conditions, which reduces inflation risk but also slows economic activity.
How to interpret this series
M1 alone is rarely a primary FX catalyst, but sustained above-trend growth is a medium-term inflation risk and may increase rate-hike probability, supporting the jpy. Contracting M1 is associated with tighter liquidity.
