Impact of a '94-style bond debacle on today's NAVs of popular Vanguard bond index funds

In November and December 1994, the NAVs of some popular Vanguard bond index funds hit their lowest levels in memory during that year's bond market meltdown. What if we revisited those lows today? How much could you lose, both in value and in time?

On the short end, VBISX at 10.53 to start the week would have to fall to 9.50 to match that debacle low from December 1994, wiping out 9.78% of value. With a duration of 2.7 years, presumably you'd have to sit tight almost three years from such a low to recoup your losses as the fund replaced its maturing issues with higher yielding short-term instruments in the new landscape. 

In the intermediate space, VBIIX at 11.46 now would have to fall to 9.16, the November 1994 low, wiping out 20.07% of value. Your duration-implied wait to recoup your losses there is 6.5 years.

VBLTX in the long term space at 13.59 today would have to fall to the November 1994 level of 8.87 to match the November 1994 low, wiping out 34.73% of value. Could you wait 14.5 years to recover from that?

Consider also VBMFX, the total bond index. At 10.82 this week it would have to fall to 9.15 to match the November 1994 meltdown low. That would wipe out 15.43% of value from here. Time to recovery based on duration of the fund? 5.6 years.

Or VFIIX, the Ginnie Mae fund. Current net asset value started the week at 10.73. That would have to fall to 9.54 to match the November 1994 meltdown low, wiping out 11.09% of value. Duration for that fund is 5.5 years.

Many Americans have fled to bond funds for safety in the wake of the financial panic 6 years ago. By doing so, they have driven NAVs to levels in such funds never before seen in their histories, helping to create a bubble. Exiting from such bubbles is not easy when everyone suddenly wants to do so at the same time.

No wonder market timer Bob Brinker of Money Talk Radio Program fame has recently gone ultra short duration for his fixed income investing. He has picked funds which have durations of about one year. That's it.

The wisdom of the move is not yet well appreciated because of what it is not telling you: that a stock market crash is coming, right after the bond market nose dives. He doesn't want to be caught booking huge bond losses in his portfolios when the opportunity to invest new cash will present itself not long after. In other words, I think this is Brinker's way of raising cash now without saying so.

Not advice. Just my humble opinion.
