This is not all. Not only is the concentration limited to the top 10 borrowers. Even in terms of sector exposure, most of the loans are given to metals and power players.
With most power plants facing fuel linkage issues and metals sector coming under pressure due to global slowdown, the stress in these companies is yet to become visible.
Like any slowdown, the accretion of stress in assets starts showing up from smaller players. To get a sense of how the stress levels are building, Barclays has done a study of operating free cash flows.
Given that top 100 companies account for 70 per cent of listed debt, it's imperative to understand what these companies are up to.
Anish Tawakley of Barclays says in his latest report, analysis of 13 large borrowers indicate these leveraged corporates are continuing to borrow to fund large capital expenditure, while their operational cash flow remain weak.
In aggregate, these companies generated negligible cash flow - a mere 0.4 per cent of revenues. Another argument made by other analysts is that some of these large corporates are using working capital loans to pay for interest.
However, June quarter numbers of banks don't yet reflect large corporate asset deterioration. SBI's bad loan accretion in Q1FY13 also indicates this trend. However, the stress in big corporates is not widespread yet.
