Perspective on global economic and fixed income developments

Bonds, bubbles, and Bitcoin

Spring 2018

Key takeaways:

  • Extreme prices, crowd euphoria, and a disconnect from fundamentals can be signs of an asset bubble.
  • We don’t believe that fixed income is in a bubble environment right now.
  • The jump in longer-term bond yields in February was primarily driven by rising inflation expectations.
  • Two-year U.S. Treasury yields are back above the dividend yield on the S&P 500® Index for the first time in about a decade.
  • Even though asset prices can reach extremes, these valuations can make sense when supported by underlying fundamentals. 

Over the past few years, stocks, bonds, and Bitcoin have inspired conversations regarding what an advisor should recommend to clients when asset prices reach extremes. This is hardly surprising, given that U.S. stocks rose to all-time highs early this year after a remarkable 2017, and at more than $9,000, Bitcoin is up by roughly 600% over the last year alone.1 In addition, fixed income credit spreads remained tight and bond yields remarkably low even as the Federal Reserve (Fed) repeatedly hiked short-term rates. Do these scenarios represent asset bubbles or have extreme valuations been fundamentally supported by rational decision making? Additionally, what characteristics tend to show up when asset valuations have reached bubble territory? To help address potential questions like these from your clients, let’s dive into this quarter’s edition of our fixed income insights.

Client insights regarding asset bubbles

Details have varied from one asset bubble to another, but three characteristics have generally surfaced: (1) extreme price levels, (2) crowd euphoria/panic buying, and (3) a disconnect from underlying fundamentals. The table below captures these characteristics where stocks, bonds, and Bitcoin are concerned.

Disconnect from fundamentals

Stocks and Bitcoin have both traded at extremes this year, fulfilling one critical ingredient in the asset-bubble equation. Crowd euphoria and panic buying for fear of missing out is an additional characteristic that these assets shared during January in particular, fulfilling a second criteria and illustrating the role that behavioral finance can play in your clients’ investment decisions. However, a potential disconnect from underlying fundamentals is where the two assets may differ.

Fundamentally assessing the underlying factors that support the value of an individual stock requires a wide range of calculations and considerations, some of which—such as P/E ratios—are subject to interpretation. At a macro level though, U.S. stocks are benefiting from corporate profit growth and solid consumer confidence, while international equities are supported by still-accommodative central bank policies in many key countries and regions. By comparison, Bitcoin’s underlying fundamentals are far more intangible, since as a startup currency, its ultimate adoption is extremely uncertain. Overall then, stocks and Bitcoin may be trading at extremes, but these levels appear to be justifiable, perhaps making their prices not so extreme after all.

Bond extremes are quite justifiable

What about bonds, are they in a bubble? For years, long-term U.S. Treasury yields have been extremely low, at least by historical standards. However, these low yields haven’t been a reflection of crowd euphoria or panic buying, but are instead a reflection of the underlying fundamentals that affect fixed income securities in general.


The extreme yield levels at which bonds are trading are justifiable from our perspective.

The U.S. economy is transitioning from a period of historically low short-term interest rates that drove yield-seeking investors ever-further out the credit- and bond-maturity spectrum, contracting yield spreads in the process. The extreme yield levels at which bonds are trading reflect this fact more than anything else, and are therefore justifiable from our perspective.

Rate hikes don’t necessitate a parallel curve shift

Given that bond yields are justifiable, your clients might be wondering if the Fed’s rate hikes were behind the jump in longer-term rates earlier this year. If so, you might consider speaking with them about the chart below. The Fed began scaling back their accommodative policies in 2015 and hiked rates 1.25% in total by the end of 2017. Yet as the chart illustrates, yields on 10-year Treasuries finished that period only about 25 basis points higher.

Even after five rate hikes by the Fed, 10-year Treasury yields were only 25 basis points (0.25%) higher than where they began.

Inflation expectations dictate the direction of longer-term rates more than any other single factor.

Inflation expectations shift

If Fed rate hikes weren’t the catalyst for the February jump in longer-term rates, what was? The short answer is inflation expectations, which dictate the direction of longer-term rates more than any other single factor. In spite of ongoing improvements in the jobs market in recent years, U.S. wage pressures have been well contained. At least that was the case until unexpectedly strong data was released for January and February. These improvements, combined with the potential effects of recent tax revisions, painted a picture of potentially faster inflation over the intermediate-term, pushing longer-term bond yields higher in February, with 10-year Treasuries reaching nearly 3.0%. That was a significant jump in yields over a fairly short period of time and might be worth discussing with your clients to address any potential concerns regarding their fixed income allocations and why longer-term rates have been rising.

A bumpy road for bonds

After the initial February yield spike, longer-term bond yields have been relatively range-bound. Worries about trade wars and the potential for a ramp up in imported inflation have played a hand, leading to a fluctuating outlook where U.S. economic prospects are concerned. We’ve witnessed a similar pattern with many of Donald Trump’s initiatives and tweets since he became president, with the markets initially pricing in a worst-case scenario that has often gone unrealized, eventually allowing the markets to self-correct.

Where do short-term rates go from here

The Fed has forecasted two more rate hikes before year-end and three subsequent rate hikes in 2019. So short-term rates are set to rise fairly quickly, creating a potential conversation opportunity with your clients.

For the first time in a decade, 2-year Treasury yields are higher than the dividend yield on the S&P 500® Index, as illustrated in the chart below. Conversations about the historically income-focused appeal of bonds—with less relative credit risk than equities—have therefore once again become relevant. Elevated levels of equity market volatility earlier this year and potential client anxieties associated with this historical return to normalcy would make such a conversation timely as well.

For the first time in more than a decade, yields on 2-year Treasuries are above the dividend yield on the S&P 500 Index.

What about longer-term rates

The outlook for longer-term rates remains hinged on inflation expectations. On one side of the equation are the tightening jobs market and recent tax changes that could fuel rising wages, more spending, and faster inflation. On the other side of the equation are sovereign debt yields across G7 countries like the U.K., France, Germany, and Japan that remain well below U.S. Treasury yields. In fact, even yields on high-yield European corporate debt are below comparable-maturity Treasuries, while representing far more credit risk. Given the global appeal of Treasuries, this should help keep a lid on any significant increase in longer-term U.S. rates, even if the Fed continues to raise the federal funds rate, as expected. As a result, we think that inflation expectations would need to rise considerably for longer-term rates to move materially higher from here.

Final takeaways for your clients

Extreme asset prices can make sense if they’re supported by underlying fundamentals. We believe that fundamental support is in place where fixed income is concerned, in spite of tight credit spreads, inflation pressures, and the favorable economic environment. Moreover, while fixed income is always a relevant asset class, it can play a particularly important role when equity markets turn volatile, anchoring the performance of your clients’ portfolios. So help your clients understand the importance of sticking to their long-term investment plan, and consider reminding them that a well-diversified portfolio should generally include an allocation to fixed income, and U.S. Treasuries in particular.
