同學(xué),下午好。
這里有勘誤,勘誤如下,
“The plan manager’s likely view is that the 30-year swap rate will be less than 3.80%. Then the gains on the receive-fixed interest rate swap exceed those on the swaption collar (i.e., not profitable until the swap rate falls below 3.60%) and on the purchased receiver swaption (i.e., not profitable until the swap rate falls sufficiently below 3.60% to recover the premium paid) as illustrated in Exhibit 16. Note that if the 30-year swap rate exceeds 3.80%, then the receive-fixed interest rate swap will begin losing immediately. Losses on the swaption collar will not begin until the rate rises above 4.25%, while losses on the purchased receiver swaption (at any swap rate above 3.60%) are limited to the premium paid. Notice that this rate view is also consistent with the concern about lower corporate bond yields and the relatively high hedging ratio.

這里擔(dān)心利率下降導(dǎo)致負(fù)債端的價值升高,而讓股票的收益抵消使得凈負(fù)債仍然很大,因此需要考慮利率下降的問題。相較而言,利率上升的影響較小。
那么在這里,在觀點是利率下降小于3.8%的前提下,purchased receiver小于3.6%才能行權(quán),并且需要支付期權(quán)費;Swaption collar小于3.6%才能行權(quán)。那么有兩個問題,第一個是3.6%到3.8%這段利率下降期沒有保護,第二個是如果在利率下降小于3.8%的前提下3.80% receive-fixed swap是不用支付費用而獲益最大的。
因此,這里需要把握兩個前提,一個是利率下降,一個是利率下降小于3.8%來考慮這三個策略的優(yōu)劣。
