How are Rate Expectations calculated:

Forecasting rate decisions is notoriously speculative, yet the market is typically very efficient at predicting rate movements (and many economists and analysts even believe the market prices influences policy decisions). To take advantage of the collective wisdom of the market in forecasting rate decisions, we will use a combination of long and short-term, risk-free interest rate assets to determine the cumulative movement the Bank of Japan will make over the coming 12 months. We have chosen the Bank of Japan as the yen is considered the proxy funding currency for carry trades.

To read this chart, any positive number represents an expected firming in the Japanese benchmark lending rate over the coming year with each point representing one basis point change. When rate expectations rise, the carry differential is expected to contract and carry trades will suffer.
