5 for 5: Prattle’s Perfect Week | MACRO MINUTES

  • Friday, September 9, 2016


In our weekly Macrocast, Prattle correctly forecast the policy outcomes of every global central bank meeting this week. Based on the trends in our quantitative sentiment data, we predicted that the European Central Bank, Reserve Bank of Australia, Swedish Riksbank, Bank of Canada, and Bank of Korea would hold interest rates–and all of them did.

We forecast an ECB hold based on the bank’s hawkish* momentum** score, and the bank followed through with a neutral (residual -0.05) policy statement and a hawkish (residual 0.88) statement delivered by ECB Governor Mario Draghi on 9/8.

Our hold call for the Reserve Bank of Australia was based on the persistently below-neutral trend from the bank leading up to the meeting. Continuing that trend, the RBA’s 9/6 interest rate statement scored very dovish with a residual of -1.94.

The Swedish Riksbank hold prediction was based on the bank’s slightly hawkish momentum of 0.27. The 9/7 announcement released by the bank scored hawkish (residual of 0.23), perpetuating the trend we identified at the beginning of the week and further meeting our expectations by mentioning potential rate hikes in 2017.

While the Bank of Canada was relatively tight-lipped leading up to its 9/7 policy meeting, we forecast a rate hold based on its slightly dovish momentum score of -0.11. The statement released by the bank scored hawkish (residual of 0.79) and matched our expectation of a rate hold.

Our system scored the Bank of Korea’s most recent set of meeting minutes as strongly hawkish (residual 1.74), leading us to forecast a rate hold at the BOK’s 9/8 meeting despite recent talk of additional cuts. The bank continued its hawkish trend by holding rates and releasing a hawkish statement (residual of 1.09).

These outcomes showcase the viability of Prattle’s sentiment data, when applied correctly, as an effective forecasting tool for global monetary policy. In fact, the accuracy of Prattle scores as a means of forecasting policy has earned a great deal of attention recently.
