The Federal Reserve raised the federal funds rate by a quarter point on Wednesday afternoon, its first rate change since Chairman Kevin Warsh took his seat in May and its first rate hike in over three years. The federal funds rate now sits between 3.75% and 4%, and projections from regional Federal Reserve presidents and Board of Governors members indicate the central bank expects to hike rates one more time this year. The Federal Open Market Committee said the hike “will support a timelier return to the Committee's 2 percent goal” for inflation, which is currently running at 3.4% and has been above the Fed’s target since 2021.

The FOMC’s brief statement pointed to “resilient” domestic spending and “robust” capital investment, while characterizing the economy as “expanding at a solid pace” with “elevated” uncertainty due to “geopolitical developments.” High oil prices from the partial shutdown of the Strait of Hormuz and high investment in data centers have helped push up Treasury yields. Warsh attributed higher Treasury yields to “economic strength, competition for capital, and geopolitics.” The yield on the 10-year Treasury bond, a benchmark for the cost of money throughout the economy, rose to over 5% on the news, the highest level since 2007.

Rising Treasury yields have made raising capital more difficult for sectors besides artificial intelligence, including the capital-intensive renewable and clean energy industries. The rate hike and higher benchmark yields increase financing costs for renewables projects, which rely heavily on upfront capital. This creates a direct headwind for clean energy deployment even as the Fed focuses on returning inflation to its 2% goal.

What remains unknown is how quickly these higher financing costs will translate into slower renewable project development or higher electricity prices for consumers. The dossier does not provide data on clean energy investment volumes, project cancellations, or utility rate impacts tied specifically to this rate hike. It is also unclear whether the expected additional rate hike this year will further pressure renewables or whether geopolitical developments affecting oil prices and Treasury yields could shift the trajectory.
