The National Statistics Institute explains that the “statistical operation Implicit Interest Rates on Housing Credit aims to provide indicators of the financial effort assumed by families and the state in housing credit. It is based on an administrative procedure using information from banking institutions submitted to the National Statistics Institute under a protocol.”
“The indicators on interest rates, average capital owed, and installment due are calculated for aggregate totals, for different financing purposes (housing construction, acquisition, and renovation), by the period of credit contract (last 3, 6, and 12 months), and also with segmentation by credit regimes,” it further explained.

The demand for loans by individuals increased in the second quarter, particularly in the housing segment, while for companies, only the demand for short-term loans and by SMEs grew, according to a survey by the BdP.
