Portfolio financing

Borrowing against a portfolio

The securities stay in the account. Cash is advanced against them. Nothing in the portfolio has to be sold to raise that cash.

Key takeaway

Borrowing against a portfolio is a loan secured by investments you still own. The securities are collateral, and they can be sold if the collateral rules stop being met.

Sell

Shares leave the account. Cash is sale proceeds.

Borrow

Shares stay. Cash is an advance against them.

What this means

A sale disposes of shares. A borrow does not. The cost of the borrow is interest, plus the broker’s right to treat the portfolio as collateral. Haven’s reference rate for that kind of financing is the Haven SPX Box Rate, read from listed SPX and SPXW options. It is not itself the loan.
