A problem this market presents to “asset liability managers” (ALM) is that the usual negative correlation between risky equity and risk free notes, strips, and bonds is approaching 0, and at times has been positive.

For instance in the 2008 to 2009 crash in risk assets, in equity markets, Us Treasurys soared in price with long duration increasing in price by 50% to 60%. This had large ALM problems survive.

Now, as correlation approaches 0, there is no offset.

A Markowitz type portfolio construct will not provide offset from riskless fixed income to equity declines.

The “risk premium” for risk free is derived, the increase in yield required to extend duration - per year in basis points.

The annual change in NGDI priced into the market is derived for that change in 7 years.

This can be seen as the growth potential in the US economy.

The US economy has, according to a forward Fisher Effect logic, increased as the Federal Reserve actions have raised long term rates. This rise has more than offset the drop in the term premium towards 0.

The “basis” of NGDI for 7 years is netting NGDI level in 7 years to current dollars NGDI.

The basis is the implicit growth priced into the US economy.

The basis is given in both then current dollars and then in percentage of the current NGDI.

The current dollars instantaneous NGDI, the NGDI level expected in 7 years, and then the basis of that 7 year forward NGDI level is used to qualify equity values overtime.
