The Fed Balance Sheet and the Taper Tantrum That Ain’t (Yet)

SUMMARY

  • In 2013, U.S. Treasury yields rose dramatically after then-Fed Chairman Ben Bernanke suggested the central bank might begin reducing its pace of monthly asset purchases. The so-called taper tantrum affected markets globally.
  • Today, the Fed is openly discussing plans to begin shrinking its balance sheet in 2017 – yet Treasury yields remain stable.
  • We see two explanations for this striking disparity in the market’s response. First, unlike in 2013, both the Fed and market participants accept the New Neutral for U.S. monetary policy. Second, the Fed plans to continue buying duration and convexity risk for at least a year after balance sheet normalization begins.

Recent communications from the Federal Reserve suggest it is likely to begin shrinking (“normalizing”) its balance sheet this year. U.S. Treasury markets have responded with what amounts to a collective yawn. Why? And could this change?

Contrast this with the turmoil that engulfed bond markets four years ago after then-Fed Chairman Ben Bernanke, in testimony before the Joint Economic Committee on 22 May 2013, made reference to the possibility that the Fed at some point would re-evaluate the third round of its asset purchase program, in place since September 2012. Bernanke suggested that at some future date, the Fed could consider reducing the program’s pace of purchasing $45 billion of U.S. Treasuries and $40 billion of mortgage-backed securities (MBS) each month. He commented, “If we see continued improvement [in the labor market outlook] and we have confidence that that is going to be sustained, then we could in the next few meetings, take a step down in our pace of purchases.” He went on to caution that this was “dependent on the data. … If the recovery were to falter, if inflation were to fall further and we felt that the current level of monetary accommodation was still appropriate, then we would delay that process.”

But there’s little doubt where most investors focused their attention. Following Bernanke’s testimony, the market reaction – dubbed the “taper tantrum” by the financial press – was swift and sharp. The yield on the 10-year Treasury note (see Figure 1) rose from 1.94% the day before the testimony in May 2013 to 3.04% percent at the end of December 2013 (two weeks after the actual tapering program was announced after the December Fed meeting). And the sell-off was not confined to the U.S., with global bond yields rising in tandem with the Treasury market.

How times change. On 24 May 2017, almost exactly four years after Bernanke’s market-rattling testimony, the Federal Open Market Committee (FOMC) released the minutes to its May 2017 meeting. The minutes indicated there was broad agreement in the FOMC to commence the process of shrinking the Fed balance sheet sometime later this year and that this process would entail setting pre-announced caps on the maximum amounts of Treasury and MBS securities that would be allowed to roll off or prepay each month. Several weeks later, right after its meeting on 13–14 June, the Fed released an “Addendum to the Policy Normalization Principles and Plans,” which reaffirmed that the FOMC would like to commence the process of balance sheet normalization later in 2017. The addendum revealed that the caps discussed above would be set initially at $4 billion per month for MBS and $6 billion per month for Treasuries, rising gradually over the next 12 months to $20 billion and $30 billion per month, respectively.

The market reaction to this momentous news in monetary policy? Instead of another tantrum, bond yields fell! See Figure 2. In late June, yields did rise somewhat, but they still didn’t reach the levels they touched in the weeks prior to the release of the May meeting minutes and remain well below their 2017 highs (from March).
