Banks large and small continue to add mortgages to their portfolios, with new additions outpacing runoff from refinances and foreclosures. The new additions to bank portfolios are largely jumbo mortgages, though some lenders are retaining agency-eligible loans. Banks and thrifts held a total of $1.76 trillion of first-lien mortgages in portfolio as of the end of the second quarter of 2014, according to an Inside Nonconforming Markets analysis of call reports. The first-lien holdings were up 1.4 percent compared with the previous quarter and level compared with the second quarter of 2013. Among the four largest holders of first liens, only Bank of America decreased its portfolio in the second quarter. Compared with the second quarter of 2013, JPMorgan Chase was the only bank among the big four to increase its first-lien holdings.
