Fiscal and monetary stimulus have stabilized markets. Looking ahead we believe risk assets could continue to outperform Treasuries despite potentially weak economic data, largely due to Fed purchases.

May 2020 Review:

  • Risk assets continued to perform well after the bottom in late March, as fiscal and monetary stimulus programs have supported markets and we begin to emerge from the depth of the economic trough. The Federal Reserve continues to taper its official purchases in Treasuries and Agency MBS to a fraction of their original pace in mid-late March.
  • Economic data reveals slight improvement off lows in late March/early April.
  • In May the 10-year Treasury yield rose 2 basis points, from 0.62% to 0.64%. However, the Treasury curve steepened noticeably, as the 5/30 spread steepened 18 basis points. The 5-year yield fell 5 basis points to 0.30%, while the 30-year yield rose 13 basis points to 1.40%. Treasuries returned -0.25%, bringing the year-to-date return to 8.61%.
  • Corporate spreads continued to fall toward their pre-pandemic levels. The corporate sector outperformed duration-matched Treasuries by 181 basis points, as the option-adjusted spread of corporates narrowed 28 basis points to close May at 174 basis points. This level is just 52 basis points wider than it stood at the end of February.
  • Buoyed by their outperformance versus Treasuries on a duration-adjusted basis, the Bloomberg Barclays U.S. Corporate and MBS indices each delivered positive absolute returns (1.56% and 0.12%, respectively). Mortgages generally maintain substantially shorter duration exposure than Treasuries, and likely benefited from the steepening of the yield curve (as their partial duration exposure tends to lie in the middle of the curve, not the 20-30 year point).
  • The portfolio (+0.42%) tracked the Bloomberg Barclays U.S. Aggregate Bond Index (+0.47%) in May. While security selection within MBS helped performance, the overweight to longer Treasuries within our Treasury allocation detracted, leaving the overall fund return basically in-line with the index.

  • The economic downturn has moderated somewhat, as we have seen modest reopening of economies globally. We appear to have averted the worst health outcomes that were forecasted 2-3 months ago.
  • Nevertheless, some parts of the risk market (equities) have noticeably decoupled from the underlying data (unemployment, mortgage delinquencies). This can partially be attributed to central bank purchases, and we can also point to the avoidance of worst-case outcomes for the remainder of the improvement. Delinquency data for non-mortgage receivables (credit cards, auto) are much better than expected, and we will continue to monitor these areas to understand the health of the consumer and the ability to emerge from this downturn.
  • Despite a deluge of corporate supply, corporate spreads narrowed in sympathy with equity outperformance. As official purchases of corporate ETFs have begun, we believe spreads can continue narrowing despite weakness in underlying economic data.
  • We maintain an overweight position in MBS, a neutral position in corporates, and an underweight to Treasuries.
  • Our highest conviction remains an overweight to mortgages – specifically lower coupon mortgage pools and mortgage derivatives off very seasoned collateral that is less sensitive to rate-induced prepayments.
