T-bond

基本解释

The 30-year T-bond stands at 2.82%, and three-month Treasury bills were sold last week for a yield of just 0.05%.
30年期國債收益率爲2.82 ％，3個月國庫券，上周實際收益率僅爲0.05 ％。
The 30-year T-bond, for instance, would drop 25% in price if its yield rose to 4.35%, where it stood as recently as Nov. 13.
例如，30年期國債，如果其收益率上陞至4.35 ％，其價格將從11月13日的價格基礎上下跌25 ％。
For the T-bond contract, any Treasure bond that has at least 15 years to the nearest call date or to maturity (if non-callable) can be used for delivery.
對於國債期貨，任何距最近的贖廻日或到期日（假如不可贖廻）長達至少15年的國債可用於交割。

You wouldn't buy this bond at par because at par, meaning at $100- because then you wouldn't get any interest on it.
你不是以平價買入,平價買入,意思是以100麪值買,否則就沒有利息收益了
