India?s 10-year bonds fell, pushing yields to a six-week high, on concern a slide in Asian stocks will spur investors to withdraw money from the region.

The securities declined the most in a week as traders returned from Wednesday holiday to see the benchmark share index slump 3.6%. Bonds also dropped on speculation government curbs on companies? overseas borrowing will further serve to reduce the funds available for banks to invest in debt.

?We are witnessing a flight to safety across global financial markets and that could lead to an outflow of money from our part of the world,? said Manoj Rane, treasurer at the Mumbai unit of BNP Paribas SA. ?There will be a big sell off in stocks today, which will have negative implications for liquidity in the banking system.?

The yield on the benchmark 7.49% note due April 2017 rose 4 basis points to 8.02% in Mumbai, according to the central bank?s trading system, the highest since July 4. The price fell 0.26, or 26 paise per Rs 100 face value, to 96.44. A basis point is 0.01 percentage point.

The Bombay Stock Exchange’s Sensitive Index, or Sensex, fell to the lowest in seven weeks as investors pared risk because of a deepening global credit squeeze.

Bonds also fell on concern debt sales by the central bank and a decline in overseas borrowing by companies will cut surplus cash in the banking system.

The Reserve Bank of India sells bonds every week under the so-called market stabilization plan to drain excess funds that may stoke inflation. The bank drained as much as Rs 6,500 crore ($1.58 billion) by selling bonds and treasury bills this week. The government on August 7 imposed curbs on borrowing abroad to slow capital inflows that pushed the currency to a nine-year high. Companies borrowing more than $20 million can’t remit the proceeds to India.
