The central bank on August10 reduced limits on how much funds banks can set aside for lending to 30 percent from 40 percent, causing yields to rise by the most in a month last week. Yields may climb further now that banks have increased deposit rates to boost liquidity, said Nguyen Thu Hong, head of the treasury department at Saigon Securities Inc. in Ho Chi Minh.

“The new 30 percent cap for banks to use their short-term funds to make on medium- and long-term loans, instead of 40 percent, has tightened money supply for investment in bonds,” said Hong.

The yield on the five-year notes rose 15 basis points to 9.96 percent, near the year’s high of 9.97 percent reached on August 18, according to a daily fixing price from about 10 banks compiled by Bloomberg. A basis point is 0.01 percentage point.
