Most personal lines of credit are unsecured. This means the borrower does not promise the lender any collateral for taking an unsecured line of credit. One exception is
home equity lines of credit (HELOC), which are secured by the equity in homes. Secured lines of credit offer the lender the right to seize the asset in case of non-payment. Because their risk is lower, secured lines of credit typically come with a higher maximum credit limit and significantly lower interest rate. On the other hand, unsecured lines of credit have higher interest rates than secured lines of credit. A borrower must have a high credit score and good repayment history to meet the eligibility criteria for getting an unsecured line of credit. Since the unsecured credit line is not backed with collateral, if the borrower defaults on payments, the lenders cannot recover their losses. Hence, the lenders can minimize their risk by charging high-interest rates and restricting the credit line limit. Besides the HELOC, another relatively common form of secured LOC is the Securities Backed Line of Credit (SBLOC). This is also commonly referred to as a Pledged Asset Line. In this version, the borrower pledges securities (typically stocks, bonds, etc.) to the lender as collateral. The lender will typically lend less than the full value of the securities pledged, applying various "haircuts," depending on the lenders' assessment of how risky the pledged security is. For example, a lender might lend up to 80% of the value of a bond, but only 50% of the value of a stock. It's important to note that these LOCs are designated as non-purpose, meaning the proceeds cannot be used to purchase additional securities, unlike a
margin loan. Because of this, the loan to value ratios are typically higher than a margin loan, although, since the financial institution can set their own LTVs, this does not necessarily have to be the case. Depending on the LTV required, a borrower can sometimes use a margin loan to achieve the same objective as an SBLOC, since they can use the proceeds of their margin loan to purchase goods and services other than securities. Borrowers, should be wary of these financial instruments, however, since they could be subject to a margin call, similar to what can happen with a margin loan, if the value of their pledged securities falls too low. Lenders also typically structure these LOCs as demand loans, meaning they have the right to demand full repayment of the loan at any time. == Revolving vs close-end LOCs ==
