Treasury yields continued rising as markets priced in a greater chance of further Federal Reserve rate increases. Higher yields are putting pressure on equities and increasing borrowing costs. Approaching 20-year highs means US Treasury yields are at their highest levels since approximately 2006-2007 — before the 2008 global financial crisis.
WHY YIELDS ARE RISING
The documented rate-increase expectation driving yields:
▸ September 28: Iran stalemate; oil rose 2%+
▸ Higher oil: inflationary pressure returns
▸ Higher inflation expectation: increases probability of Fed second rate hike
▸ Higher rate hike probability: drives Treasury yields higher as investors demand more return to compensate for the rate risk
▸ 20-year high yields: the cumulative documented outcome of seven months of Iran war energy disruption and the September 28-29 stalemate
WHAT 20-YEAR HIGH YIELDS MEAN
US Treasury yields are the benchmark from which other borrowing costs are set: mortgages, corporate bonds, auto loans, student loans. When Treasury yields approach 20-year highs, it means that the borrowing cost baseline for the entire US economy is approaching its highest level in two decades. American families, businesses, and governments borrowing money today are doing so at rates not seen since before the 2008 financial crisis.
US bond yields are approaching 20-year highs because markets think the Fed will raise rates again because oil is rising because the Iran deal is at a stalemate. That chain from a Strait of Hormuz negotiation to a 20-year high in US borrowing costs is documented in full. The people on the end of that chain are buying homes, taking out car loans, and carrying credit card debt at rates they haven’t seen in 20 years.
WHAT HAPPENS NEXT
▸ Fed speakers — whether today’s scheduled Fed remarks confirm or walk back the second hike expectation
▸ October 6 — whether an Iran deal resolution reduces oil and the yield pressure
▸ Equity pressure — whether 20-year high yields produce sustained market decline
| CONFIDENCE: HIGH | Treasury yields continued rising; markets priced a greater chance of Fed rate increases, higher yields pressuring equities, and increasing borrowing costs, according to confirmed reporting. |
