, given that banks participating in eurosystem refinancing operations must offer collateral to obtain liquidity, we decided to ease the collateral framework conditions so that they could obtain a greater amount of financing in these operations. the measures adopted included most notably reducing the average haircut applied to the value of the collateral and accepting higher - risk assets as eligible, including loans backed by the national authorities ’ various programmes. thirdly, the importance of the ecb ’ s flexibility as regards the recalibration and use of instruments should be highlighted. by way of illustration, the evolution of the economic crisis caused by the pandemic required an increase in the pepp in june of €600 billion, and of €500 billion in december, up to a total of €1. 85 trillion. the net purchase horizon was also extended until at least end - march 2022 and the maturing securities reinvestment horizon until at least end - 2023. in december we also decided to recalibrate the conditions of the tltros. we extended by 12 months, until june 2022, the period during which the reduced interest rate for banks meeting the lending target will be applicable, scheduling three additional quarterly operations between june and december 2021, and increasing the borrowing allowance of tltro funds each bank can obtain from 50 % to 55 % of its eligible loans. another of our decisions was to extend until june 2022 the aforementioned collateral framework flexibility measures. but apart from this flexibility in the response over time, there is a key difference in the pepp compared with the previous asset purchase programme ( app ). whereas the app retains a relatively rigid structure regarding the distribution of asset purchases both over time and across jurisdictions, the pepp afforded itself from the outset the possibility of concentrating these purchases in the most critical months of the crisis and in the countries which, at each point in time, have been subject to tighter financing conditions. perfectly illustrating this flexibility in the distribution of purchases over time is the fact that the average monthly pace of purchases in the april - june period was €113 billion, whereas from october to december, against a backdrop of greater easing in sovereign debt markets, average monthly purchases barely exceeded €60 billion. thanks to this flexibility, along with the large volume of asset purchases initially envisaged, the announcement of the creation of the pepp on 18 march helped substantially reduce sovereign yields in the euro area, particularly in countries such as italy and spain. these countries had relatively high levels
