"If you ask me, there shouldn't be any regulatory arbitrage. Regulatory arbitrage always makes for an un-level playing field. And if you have a particular area that you are operating in, there should be level playing field so that the most efficient of them do the best job," Bhattacharya told reporters on the sidelines of the Credai-BankCon summit here.
She admitted that the main reason for this arbitrage is the higher cost that housing finance companies pay for funds.
"I still believe that there is a place for teaser loans, mainly because when people take loans, they need some breathing space in the initial days and as time progresses, the EMIs become easier (to pay) as salaries go up," Bhattacharya said.
Within two-three years, the EMI does not hurt the borrower as in the first two years and so a variable EMI is something which makes things easier, she explained.
Early this decade, the then SBI chairman Om Prakash Bhatt started off the trend of teaser loans, which after initial criticism, was adopted across the industry.
