NTPC Ltd.

NTPC, the country's largest power producer, has scrapped its bond sale scheduled for Thursday after a sell-off in government bonds sparked concerns over the pricing of its debt, given that corporate bonds are priced on the government bond yield curve. The firm was planning to raise up to Rs 10 billion through an issue of dual tranche bonds.

Trading in some government debt securities was halted earlier in the day due to circuit breakers, but was later resumed after the country's fixed income association sought the central bank's approval to raise the upper trading limits.

The benchmark 10-year government bond rose as much as 10 bps from its previous close on account of large bond sell-off after Fed said that it may start scaling back its $85 billion a month in bond purchases this year and ends them by mid-2014.

NTPC is the largest power generating company in the country. It has also diversified into hydro power, coal mining, power equipment manufacturing, oil & gas exploration, power trading & distribution.
