Thank you.FWIW, it is business as usual and we have no exposure to SVB, Signature Bank or even First Republic. As many mention above, the issue with SVB was their investment in long term bonds (average duration according to their financials of 5.7 years as/of 12/31/22) and cash on hand. They simply didn't have the liquidity to handle the amount of withdrawals and due to the rise in interest rates, if they had to sell their bonds, they would have suffered losses larger than cash required to cover the withdrawals.
At IBKR, the average duration of our portfolio is 30-40 days and while we have to report mark to market monthly to regulators, we do this daily and thus have a great handle on cash/risk management. Thomas Peterffy, chairman and founder of IBKR, was on CNBC explaining much of the same last night. link here but they got the title wrong, it is BILLION not million: https://www.cnbc.com/video/2023/03/...on-in-cash-says-chairman-thomas-peterffy.html
Is it correct that if you have a margin account at IB and IB failed, which I of course agree is highly unlikely, you cannot eliminate the risk by owning stocks, bonds or ETFs as they are not held in the name of the individual account holder. You would not be able to point at those stocks, bonds and ETFs and say: "Those are mine. I am not affected by the bankruptcy." Is that correct?
