Non-GC refers to non-general collateral and collateral-driven repo transactions. The chart displays the average spread of the respective repo rate to the € since the beginning of 2022. The latest observations are for 13 September 2022. Moreover, there has been a widening of the spread between short-term government bill rates and swaps with the same maturity (Chart 1).
But I'm reminded of that observation as I accept this award - an award for achievement in a medium that barely existed ten years ago. For that matter, it was only eight years ago - in 1995 - that the Banco de México, the Bank of Canada, and a few other central banks launched their first Web sites.
