There are various phases, so we were engaging in quantitative easing; we began in October 2020 what we call tapering or reducing the amount of quantitative easing we were providing, so buying fewer bonds. We started with five billion per week; we went to four, to three, to two and then we ended quantitative easing, which means we entered something we call the reinvestment phase, in which we only buy enough government bonds to replace the bonds that are maturing on our balance sheet.
Right now, we are in the reinvestment phase. What we indicated yesterday is that we will be considering moving to the next phase. We had indicated that we would stay in reinvestment until we raised the policy rate. Yesterday, we raised the policy rate, so the logical next step is to consider not replacing the bonds that are maturing on our balance sheet, which is called quantitative tightening, and we indicated that we would be considering quantitative tightening and when to start it. As I said earlier today, I think you can take from that that at our next monetary policy decision in April we will have a live discussion about ending reinvestment and beginning quantitative tightening.
When we get to quantitative tightening, what that means is we won't be replacing the Government of Canada bonds that are maturing on our balance sheet, so our holdings of Government of Canada bonds would diminish. To give you a picture of the speed of that, about 40% of the government bonds on our balance sheet would roll off over two years.
