Source discrepancies

What the warehouse found when it checked this series: the same figure from two agencies, splice overlaps, published rates against ones recalculated from the index, and outliers.

  • Error in the source14 Aug 2008

    This series reads 99.98; the same figure from the other source reads 161.6. Compared with LK.EXT.FX_DAILY_TT.CHF.SELL.D.

    Two agencies: 161.58 and 99.98, difference 61.6.

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 161.5800 vs Data Library 99.9800. File reads 161.58; both the day before (100.38) and after (99.06) in the file, and the Data Library's own value for this date (99.98), sit around 100 - the file's single-day figure is the outlier. Source data-entry error.

  • Error in the source6 Oct 2015

    This series reads 147.8; the same figure from the other source reads 153.3. Compared with LK.EXT.FX_DAILY_TT.CHF.SELL.D.

    Two agencies: 153.26 and 147.76, difference 5.5.

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 153.2600 vs Data Library 147.7600. Whole-day anomaly in the source file: every daily-TT currency (buy and sell) jumps on this one day while every neighbouring day matches the Data Library exactly (e.g. USD/BUY 144.53 here vs 138.9x the day before and after, in both the file and the Library) - re-verified series by series. A single bad row in IF_Buying_Selling_Exchange_Rates...xlsx, not a parsing issue.

  • Error in the source13 Jun 2017

    This series reads 160.7; the same figure from the other source reads 160.1. Compared with LK.EXT.FX_DAILY_TT.CHF.SELL.D.

    Two agencies: 160.05 and 160.65, difference −0.6.

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 160.0500 vs Data Library 160.6500. File reads 160.05 where its own neighbouring days (160.73-160.83) and the Library's value for the same date (160.65) sit at ~160.7-160.8 - a modest (0.6) but consistent single-day dip in the file only. Source data-entry error.

  • Error in the source1 Oct 2018

    This series reads 175.6; the same figure from the other source reads 185.3. Compared with LK.EXT.FX_DAILY_TT.CHF.SELL.D.

    Two agencies: 185.297 and 175.6, difference 9.697.

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 185.2965 vs Data Library 175.6000. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.

  • Rounding26 Apr 2018

    This series reads 163.1; the same figure from the other source reads 163.1. Compared with LK.EXT.FX_DAILY_TT.CHF.SELL.D.

    Two agencies: 163.114 and 163.13, difference −0.016.

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: IF_Buying_Selling file vs the Data Library

    LK.EXT.FX_DAILY_TT.CHF.SELL.D: value 163.1143 vs Data Library 163.1300. Every currency differs from the Data Library by under 0.2 LKR on this date - the file records 4 decimal places (e.g. USD/BUY 155.5247) where the Library's copy has 2 (155.43); a precision/rounding difference between two CBSL publications of the same TT rate, not an error.

    CBSL's exchange rate lookup pages against the Data Library

    CBSL's exchange rate lookup and the Data Library disagree on 13-18 days per currency between 2010 and April 2018, by a few cents to a few rupees (USD sell 2011-02-28: 91.67 in the lookup, 111.67 in the library).
