Hazy Outlooks for Monetary Policy, Virus Roil Yield Curves and Boost Bonds

U.S. Treasuries rode a wave of momentum into December amid a confluence of perceived risks around the outlooks for central bank policy, inflation, and a new variant of COVID-19. In response, investors have bid up prices of sovereign bonds, pushing yields lower, while stocks suffered losses.

The risks driving these moves may persist into year-end and could contribute to volatility across financial markets. The U.S. Federal Reserve now faces a balancing act as it looks to taper the bond-buying program it implemented last year to counteract the economic effects of the pandemic. Other central banks confront similar policy challenges.

Making waves across yield curves

The U.S. yield curve seesawed in November, reflecting shifting expectations for inflation and monetary policy.

Treasuries rallied at the start of the month as the spread between the five-year note and the 30-year bond, known as the 5s30s yield curve, steepened. This came after dovish moves from some central banks surprised investors, including the Bank of England (BOE) maintaining its policy rate rather than raising it, and European Central Bank (ECB) pushing back against market pricing that signaled expectations for interest rate hikes.

U.S. yields then moved higher toward mid-month, led by the front end of the curve, after data showed a continued acceleration in inflation, and as several Fed officials spoke about increasing the pace of tapering. The 5s30s yield curve flattened to 60 basis points (bps), a level not seen since early 2020.
