One of the more noteworthy developments during the first month of the new year was the steady sell-off in the U.S. Treasury (UST) market. While the headlines have tended to focus on January 2018 developments, the rise in rates has actually been occurring for an even longer period. For fixed income investors, the key question is: How has my core position weathered the storm of higher rates?

I’ve written extensively about the Fed’s role in pushing short-term rates higher, but this time around, the whole yield curve has experienced an elevated trend. Going back to my earlier point, the increase in rates actually goes back to September 7 of last year when the UST 10-Year yield printed its most recent low watermark of 2.04%. Since then, as of this writing, the yield has risen 67 basis points (bps) through the end of January, revisiting levels not witnessed since 2014.

For many fixed income investors, their core fixed income strategy focuses on the Bloomberg Barclays U.S. Aggregate Index, or the Agg. However, as discussed in our July 19, 2017, blog post “Fixed Income Smart Beta: An Evolutionary Tale”, WisdomTree sought to address the counterintuitive features of market cap-based indexing and applied a rules-based approach to core fixed income, where we reweighted the sectors of the Agg. The result was the Bloomberg Barclays U.S. Aggregate Enhanced Yield Index, which is over-weight in investment-grade credit and under-weight in Treasuries. By reducing the market cap-based allocation to Treasuries, this index can potentially help to mitigate the elevated interest rate risk that Treasuries may experience. 

The current back-up in UST yields offered a “real-time” illustration to see how these two different approaches to core investing performed. When interest rates rise, as we have seen since early September, it is difficult for core fixed income investments to avoid a negative outcome of some sort, with the goal being that one can keep losses to a minimum. As the chart shows, the here , which is designed to track the Bloomberg Barclays U.S. Aggregate Enhanced Yield Index, has outperformed the Agg by 52 bps during the period under review, keeping the negative return at a modest -1.02% versus -1.54% for the Agg.
