Why Central Bank Policy Rate matters for JPY
Policy rate differentials between countries are the primary driver of carry-trade positioning and long-run FX equilibrium. When the Bank of Japan is hiking while others are on hold, the jpy typically appreciates on an interest rate differential basis.
How to interpret this series
A surprise rate hike is jpy-positive; a surprise cut is negative. Forward guidance and the policy statement accompanying each decision are often more market-moving than the rate change itself, as markets are usually well-positioned for the expected move.
