It is a Bloomberg grab of the chart displaying the movement (for the last three years) in
a) the 5 year government bond yield; and
b) the 5 year swap rate denoted by the overnight indexed swap (OIS)
in the Indian money and bond markets.
Now we all know that the swap rate is an inter bank rate and hence should have an element of credit risk embedded. The government bond yield should, of course, reflect sovereign rates and is therefore free from credit risk.
This suggests that the swap rates should be higher than the yield on government bonds. In other words the swap curve should trade higher than the government bond curve. This is true for all mature markets.
However our picture above shows that the swap curve has, consistently, traded below the government bond curve.
An anomaly that I have been unable to fathom. What really puzzles me is that bank treasurers have not really used the swap market to fund their liability positions. If they had, this anomaly would have disappeared as quickly as it appeared. Given that bank treasurers are a clever lot, there must be a clear and logical reason for this situation.
Anybody with any ideas on this?
Of late - during the last month or so - the swap curve has caught up with the government bond curve. Is sanity returning? Will the swap curve now trade at a premium - as it should logically do so?
