Shorting US Treasuries

√úbersicht: 

Interactive Brokers clients have the ability to gain direct exposure to US Treasuries on both the short and long side of the market.

 

Order Entry

Orders can be entered via TWS or through IBKR’s Bond Desk.

 

Cost to Borrow

The borrow fee to short US Treasuries is based on IBKR’s borrow cost and is subject to daily change. If the Treasury is borrowed by Interactive Brokers at the General Collateral rate, the customer does not incur a borrow fee.

 

Interest Income

Customers earn Short Credit Interest on their short US Treasury positions based on IBKR’s standard tiered rates.

 

Margin Requirements

Margin1 requirements on Short US Treasury positions are the same as Long US Treasury positions. The requirement is between 1% and 9%, depending on time to maturity. The proceeds of the short sale are not available for withdrawal. The amount available for withdrawal is generally Equity with Loan Value – Initial Margin.

Additional information on fixed income margin requirements can be found here.

 

Commissions

Selling short US Treasuries incurs the same commission cost as buying US Treasuries. IBKR’s commission schedule can be found here.
 

Additional Considerations

Minimum short position size is $10M face value per CUSIP due to limitations of the US Treasury borrow market. Once the minimum position size is met, the minimum order increment is $1M (as long as the resulting short position remains higher than $10M face value).

When a short US Treasury position is held over the record date, the borrower’s account will be debited a payment-in-lieu of interest charge equal to the interest payment owed to the lender.

 

Eligible US Treasuries for Shorting

US Treasuries with an outstanding value greater than $14 Billion can be sold short.

US TIPs, STRIPs, TF (Floating Rate Notes) and WITFs (When-Issued Floating Rate Notes) are not available for shorting. Non-US sovereign debt is also not available for shorting.
