Explanation:

 Essentially, private investment and household/government saving (Table 1). Based on the break-up of investment and saving, that is available up to 2015-16, private investment accounts for 5 percentage points out of the 6.3 percentage point overall investment decline over 2007-08 and 2015-16. The fall in saving, by about 8 percentage points over the same period, has been driven almost equally by a fall in household and public saving. The fall in household saving has in turn been driven by a fall in physical saving, partly offset by an increase in the holding of financial assets. Within the latter, there has been a shift from currency and bank deposits towards market instruments, viz. shares and debentures, as discussed in Chapter 1 of Economic Survey 2017-18, Volume 2.
