Explanation:

Both are correct
A Teaser loan is nothing, but, a special loan that is offered for a fixed duration and could then be withdrawn. It generally offers a low interest rate in the initial years or some special offer and then gets back to the normal interest rates.
In India the State Bank of India had two Teaser home Loans including the SBI Easy Home Loan and SBI Advantage Home Loan, but, they were later withdrawn. These loans offered a lower interest rate for the first three years and then the normal rate.
The Reserve Bank of India had insisted that there be a higher provisioning for such loans as they carry a higher risk of default. However, banks have been insisting that these loans are given based on thorough scrutiny and the risk remains just as with other loans. A few years ago HDFC, Chairman Deepak Parekh had highlighted the risks involved with these type of loans. these could lure people with their low interest rates initially but as interest rates rise it may become harder nad harder for the people to repay thereby increasing chances of default
In India it is a common practice to issue teaser loans, especially teaser home loans. In fact, in the last few years a number of leading institutions like State Bank of India Teaser Home Loan was offered.
