How much can you rely on our Dollar-Rupee forecasts? One way we answer that question is by measuring and tracking our Reliability over time. Incidentally, we are the only forecasters to publish an 11-year reliability track on its website.

Another way to assess that is to ask, “If Dollar-Rupee moves “x” Rupees in one year, how much out of that “x” is captured by our forecasts?”

The blue line charts how many Rupees USDINR has moved over the previous 12 months. The value corresponding to Mar-09 is 10.91. This means that USDINR moved up by Rupees 10.91 between Mar ’08 (40.35) and Mar-09 (51.26). As against this, the green line says that we were able to predict Rupees 5.55 of the upmove.  In other words, our forecasts were successful in capturing Rupees 5.55 (51%) out of the actual movement of Rupees 10.91.

How does that work? After Mar-08 (when USDINR was 40.35) and till Mar-09 (when USDINR was 51.26), we made 12 forecasts for the price which was expected to prevail in Mar-09. The average of these 12 forecasts was 45.90, compared to the actual 51.26 that prevailed in Mar-09. Thus, we predicted a movement of Rupees 5.55 (45.90 – 40.35) in USDINR over this 12 month period, as compared to the actual movement of Rupees 10.91 (51.26 – 40.35). This captured movement of Rupees 5.55 is shown by the green line on the graph.

We didn’t meet our own expectations from Dec’11 to Feb’14 when the median gap between blue and green was approximately 3.21 points (median proportion of actual movement captured in this period was 56%).

However, over the years we have tried to improve our forecasting capabilities and consequently, the results for the period Mar’14 to Dec’17 have shown a marked improvement – the median gap reduced to -0.19 points. In other words, median proportion of the actual Dollar-Rupee movement captured by our forecasts was 78%. It is our aim to increase the “captured” movement from the current 78% to at least 85% over time.

We ask very hard questions about our performance to ourselves, well before any of our Clients do. And we try and answer the question very objectively. This is a necessary first step to ongoing improvement and results in increased reliability of our forecasts for our Clients.
