1. Decline in market interest rate: If the overall market interest rate falls, the bank will reduce the loan interest rate accordingly to attract more borrowers. This has caused the interest rate of your stock house loan to drop.
2. Policy adjustment of the central bank: The central bank will influence the interest rate of the financial market by adjusting the benchmark interest rate or other policies. If the central bank announces lowering the benchmark interest rate or other interest rate-related policies, the bank will adjust the loan interest rate accordingly.
3. Improvement of the borrower's credit rating: If your credit rating is improved, the bank will adjust your loan interest rate. A higher credit rating usually means lower risk, and banks are willing to provide you with more competitive interest rates.
