BBH Inflation-Indexed Fixed Income Quarterly Strategy Update – 3Q 2022

September 30, 2022
Portfolio Co-Managers, James Evans & Jorge Aseff, provide an analysis of the investment environment and most recent quarter-end results of the Inflation-Indexed Fixed Income strategy.

3Q Highlights

  • The Fund outperformed its benchmarks by 15 basis points last quarter.1
  • Market-implied inflation expectations near 2% and inflation likely to stay elevated for longer present very attractive opportunities to acquire inflation protection. We think this provides opportunities for investors to create or add allocations to TIPS.

A New Hawk

In the second half of 2020, when supply chains were severely disrupted, coordinated fiscal and monetary expansions stimulated aggregate demand, causing prices to rise quickly. Given the nature of the process, Federal Reserve (Fed) Chair Jerome Powell qualified the resulting inflationary episode as transitory, expecting inflation to stabilize on its own as demand normalized and supply bottlenecks eased. That was then. Once Powell realized the persistence and severity of inflation, he found his inner hawk and decided to unleash a Great Tightening of interest rates to bring back price stability. For the first time since the era of interest rate targeting began, the Fed increased the funds rate by 75 basis points[1]in three consecutive meetings. The funds rate has increased 300 basis points since March, both the nominal and the real yield curves have increased by more than 200 basis points year-to-date, and rate volatility returned to levels not seen since before the Global Financial Crisis (GFC). The impact on financial markets has been devastating, with bonds and equities posting double-digit losses this year.

The quintessential barometer of fixed income markets is known as the Agg, short for the Bloomberg U.S. Aggregate Index. The Agg lost 4.75% in Q3 and 14.61% in 2022, the lowest return on record. These fixed income losses were driven by the selloff in Treasuries, which lost 4.3% in Q3 and 13% year-to-date. The size and speed of rate increases overwhelmed other sources of bond returns. Treasury Inflation Protected Securities (TIPS) constitute a perfect example, where the selloff in real rates eliminated more than 7% of inflation compensation embedded in TIPS. Real yields near the 10-year maturity increased more than 100 basis points in the quarter and more than 275 basis points year-to-date, causing TIPS to lose 5.14% in Q3 and 13.61% year-to-date. Market-implied inflation expectations (breakevens) at the 5-year maturity point dropped almost 50 basis points in Q3, falling to 2.16%, the same level touched in March 2021 (see Exhibit I).

Performance and Positioning

Our TIPS portfolios outperformed their benchmarks by 15 basis points last quarter, extending year-to-date outperformance to 25 basis points. Our strategies based on seasonal patterns, term structure positioning, and TIPS auction cycle contributed to outperformance. Similarly, our breakeven position in accounts with futures authority contributed to outperformance. Motivated by Fed tightening, we kept our term structure allocation slightly behind the benchmark in terms of duration, and added a flattening bias expressed in the intermediate-to-long parts of the real yield curve. Following the selloff in real yields by the end of Q3 and the subsequent underperformance of TIPS relative to nominal Treasuries, valuations became more favorable, and we positioned our portfolios with a slight overweight.

The Great Tightening

The Fed is increasing rates at the most aggressive pace since the era of interest rate targeting began in late-1987. Since then, the Federal Open Market Committee (FOMC) raised the policy rate in 45 meetings (see Exhibit II). The FOMC increased the funds rate by 75 basis points only four times, once in 1994, and three times in the current cycle. Although the funds rate increased 425 basis points between 2004 and 2006, it occurred at a pace of about 18 basis points per month. This year, the Fed increased the policy rate 300 basis points since March; a pace of 50 basis points per month. As of September 30th, fed funds futures imply the FOMC will deliver a fourth consecutive 75-basis points increase in November, and a 50-basis points increase in December, leaving the fed funds rate at 4.5% by year end.

In addition to normalizing rate levels, the Great Tightening is normalizing interest rate volatility. Consider the daily changes of the 2-year nominal Treasury rate since 1987 (see Exhibit III). The red lines enclose the range containing 90% of daily fluctuations in three distinct periods. Until the GFC, 90% of daily fluctuations remained within -10 and 10 basis points. The width of the 90%-interval compressed to -5 to 5 basis points from 2010 until 2021, when the Fed kept the funds rate at the zero lower bound. The most recent 90% interval, after November 2021, resembles the pre-GFC period, with daily changes between -10 and 13 basis points (a bit biased upward given Fed tightening). The rate normalization process has devastated markets this year, but it is also bringing back opportunities that had been suppressed by Fed policy for over a decade.

Exhibit III: The graph shows daily fluctuations going back to late 1987. Before the Global Financial Crisis, 90% of daily changes in the 2-year rate stayed with -10 and 10, this 90% interval compressed to between -5 and 5 basis points until November 2021. Since then, daily rate fluctuations have been between -10 and 13 basis points.

Is The Great Tightening Working?

Inflation is a process, and so is disinflation. In that sense, it is too soon to assess the impact of ongoing monetary policy. Markets on the other hand, express their views immediately. Medium- and long-term market-implied inflation expectations remained anchored throughout the inflationary process, staying within a reasonable range of the 2% target. That is a huge vote of confidence in the Fed’s ability to bring back price stability. By the end of Q3, even energy-sensitive short-maturity breakevens hovered around 2% (see Exhibit IV).

The graph contrasts market-implied inflation expectations (breakevens) and actual underlying inflation. Breakevens have remained below 3% almost all the time, even though underlying inflation exceeded 6%.

In terms of actual inflation, goods prices have calmed down, largely because as the economy returned to its pre-COVID dynamism, consumption shifted to services. Additionally, price pressures from disrupted supply chains have eased, and a strong U.S. dollar makes imports cheaper. Services have been driving underlying inflation. Shelter, or rent inflation, accounts for 40% of core Consumer Price Index (CPI) and has kept core inflation running strong (see Exhibit V). We think this could continue for longer. Alternative indicators of rent inflation, such as Zillow’s rent index have already slowed down, but this indicator leads shelter by several months; therefore, we would not expect shelter to ease any time soon (see Exhibit VI).

The graph shows the composition of core monthly inflation. Over the last few months, monthly inflation has been driven by services, especially rent inflation.


The graph shows that the Zillow rent index leads CPI shelter inflation by six about months, indicating that CPI shelter is likely to remain strong for a while.


Financial conditions have tightened to restrictive levels, with mortgage rates close to 7% and equity market losses driving negative wealth effects. Yet, the Fed remains confident they will attain an immaculate disinflation. Their Summary of Economic Projections shows inflation within 2% by 2024 at an unemployment rate only 1% higher than the current level. The Fed’s confidence rests on the notion that job openings have reached historical highs. Therefore, as financial conditions restrict economic activity, job openings will fall, easing wage pressures as unemployment rises. Since their peak in March, job openings have fallen by 1.8 million, wage growth has stayed flat at 6.7% since June, and unemployment moved only a little around 3.5%. The job market may be approaching a turning point, but for now it remains a source of inflationary pressure and will not deter the Fed from keeping financial conditions restrictive for longer.


The Fed will stay hawkish, operating with a singular-mandate mindset of price stability. But preserving maximum employment is a policy principle too, and eventually the trade-off will change. Although futures markets expect the Fed might pause around May 2023, we do not know for certain when this will happen, and there is much uncertainty around the path ahead for interest rates and inflation. Market-implied inflation expectations near 2%, underlying inflation over 6%, and likely to stay elevated for longer, present very attractive opportunities to acquire inflation protection. We think this provides opportunities for investors to create or add allocations to TIPS.
