How These Probabilities Are Calculated

The forecasts on this page are market-implied, not opinion. Overnight index swaps referencing TONAR settle on the realised overnight rate, so the forward rates between two monetary policy meeting dates reveal where the market expects the policy rate to sit after each decision. Comparing the implied rate either side of a meeting, and assuming the Bank of Japan moves in standard increments, gives the probability of a hike, hold or cut. The same curve construction powers the forward curves and swap pricing in the BlueGamma app.

The next meeting is one point on the curve.
