Cost to hold long/short portfolio IB?

  1. Hi, does anyone know how a long/short portfolio is margined at IB? Not the risk component but the financing costs?

    Let's say I'm holding 100k of stocks (diversified, highly correlated with SP500) and I'm short 100k of SPY. My best guess is I pay the borrowing rate on the long stock and receive the short rebate rate on the short stock.

    Any ideas?
