The Fed Is Cutting Rates Again—But How Low Is Low Enough?

Introduction to Interest Rates

The Federal Reserve, the central bank of the United States, has been cutting interest rates. This move is aimed at balancing the economy, but the question remains: how will officials know when enough is enough? The answer to this question could significantly impact borrowing costs for everything from cars to houses for years to come.

Understanding the Neutral Rate

At its core, the Federal Reserve is seeking an interest rate that has a neutral effect on the economy. This means a rate that does not overly stimulate the economy by making borrowing too cheap, nor does it hold the economy back by making loans too expensive. This ideal rate is often referred to as the "Goldilocks rate" – not too high, not too low, but just right. However, determining this rate is challenging because it’s based on estimates rather than precise figures.

Challenges in Finding the Neutral Rate

Fed officials have a wide range of views on what constitutes a neutral rate. Their most recent projections suggest the long-term neutral rate could be anywhere between 2.6% and 3.9%. If the neutral rate is on the higher end of this spectrum, the Fed may have limited room to cut interest rates further, given that its benchmark interest rate is already at a target range of 4% to 4.25%. On the other hand, if the neutral rate is closer to 2.5%, the Fed has more room to maneuver and cut rates.

Why the Neutral Rate Matters

The difference in interest rates may seem small, but its impact is significant, especially for long-term borrowing such as 30-year mortgages. Keeping rates unnecessarily high could lead to a recession and job losses. Conversely, if rates are too low for too long, it could stimulate the economy but also lead to inflation or other economic imbalances.

The Era of Low Interest Rates

In the years leading up to the COVID-19 pandemic, there was a notable decline in the neutral rate, also known as r-star. This decline was attributed to several factors, including demographics, where baby boomers nearing retirement invested in less risky assets, and declining birth rates in major economies, which led to fewer workers and dampened growth potential. The world was also recovering from the 2008 financial crisis, leading to an era of "secular stagnation," where savings were high and spending was low.

Factors Influencing the Neutral Rate

Demographics and global trends were responsible for much of the decline in interest rates between 1990 and 2019. However, the pace of population aging has slowed, putting less downward pressure on interest rates. Other factors, such as low productivity, continue to weigh on the neutral rate. Models suggest that demographics and low productivity will continue to influence the neutral rate, making the era of low r-star far from over.

Post-COVID Developments

Since the COVID-19 pandemic, there have been shifts in the global economy that could influence the neutral rate. The impact of artificial intelligence (AI) is a key debate, with some economists arguing it could boost productivity and raise the economy’s potential output. However, factors like immigration policies could also play a role, potentially holding back economic growth by reducing the labor force.

Rising Neutral Rate Concerns

If the neutral rate does rise, it could lead to higher interest rates, making borrowing more expensive. This could have significant implications, including the risk of fiscal crises as government interest payments increase. Investors have shown concern over rising debt levels in countries like Japan, the UK, and France, where fiscal issues have prompted political crises.

Conclusion

The Federal Reserve’s challenge in finding the perfect balance for interest rates is complex and influenced by a myriad of factors, including demographics, productivity, technological advancements, and global economic trends. As the world navigates the post-COVID economic landscape, understanding the neutral rate and its implications is crucial for policymakers, investors, and individuals alike. The future of interest rates will depend on how these factors evolve and interact, potentially leading to a shift away from the era of low interest rates and towards a new economic normal.
