In contrast, the Fed’s H.8 was tracking down $2bn on the quarter with our

market-value adjustments; however, that series comes closer to tying out (at

least directionally) when you include agency CMBS (+$3.1bn) and MBS held

in trading at the bank level (-$21.1bn). The Fed’s H.8 series shows $25bn of net

buying for the first three weeks of July (Figure 3)
