Global Market: Fed pause sparks Treasury twist, rattles bond markets

The US Federal Reserve's decision to leave interest rates unchanged has triggered a sharp shift in the Treasury market, with investors questioning the central bank's commitment to tackling inflation. The move has led to an unusual steepening of the US Treasury yield curve, as shorter-dated yields declined while long-term yields climbed sharply.

The market reaction came despite Fed Chair Kevin Warsh signalling that policymakers remain prepared to tighten monetary policy further if inflation does not ease. Investors, however, appeared unconvinced that another rate hike is imminent, leading to a widening gap between short- and long-term Treasury yields.

Long-term bond yields surge

Following the Fed's policy announcement, Treasury yields initially fell across maturities as markets welcomed the absence of an immediate rate increase. However, the trend quickly reversed at the long end of the curve.


Yields on longer-dated Treasury securities, particularly the 30-year bond, surged to their highest level in 19 years, while shorter-term yields continued to fall. The move created what market participants described as a "twist steepener"—an uncommon shift in which long-term borrowing costs rise even as short-term yields decline.

The steepening continued into Thursday, with the spread between two-year and 10-year, as well as two-year and 30-year, Treasury yields widening further.

Investors question Fed's resolve

Market participants interpreted the move as a sign that investors are becoming less confident the Fed is prepared to resume raising interest rates if inflation remains elevated.

Analysts said the Treasury market is signalling expectations that the Fed is unlikely to embark on another aggressive tightening cycle. While that could support economic growth, it may also raise doubts about the central bank's ability to keep inflation under control.

Some analysts added that the Fed may have opted to hold rates steady because financial conditions have already tightened significantly, with Treasury yields rising independently as investors respond directly to economic data.

The benchmark 10-year Treasury yield has climbed about 25 basis points in July, marking its biggest monthly increase since March.

Unusual yield curve movement

A steepening yield curve typically occurs when long-term yields rise faster than short-term yields amid expectations of stronger growth or higher inflation. This time, however, the pattern has been different.

Short-term yields declined while long-term yields continued to rise, reflecting a reassessment of expectations that the Fed would continue tightening monetary policy after geopolitical tensions in the Middle East had fuelled inflation concerns.

Before the Fed meeting, markets had largely priced in another 25-basis-point rate hike by September, and the gap between two-year and 10-year Treasury yields had narrowed as investors anticipated further tightening.

Credibility concerns emerge

Some strategists believe the latest market moves suggest the Fed has lost some of the inflation-fighting credibility it regained after its June policy meeting.

Analysts argued that the absence of a strong signal that further rate hikes remain on the table has left investors uncertain about the Fed's policy direction. Others said the central bank's decision to offer less forward guidance has resulted in inflation concerns being reflected more heavily in long-term bond prices.

Payrolls report in focus

Attention now turns to next week's US July nonfarm payrolls report, which could reshape expectations for future monetary policy.

A stronger-than-expected jobs report could reinforce concerns that the Fed should have raised interest rates at its latest meeting, potentially leading to further steepening of the Treasury yield curve. Conversely, weaker employment data could ease inflation fears and reverse some of the recent moves in the bond market.

The payrolls report is expected to test whether investors' doubts about the Fed's inflation-fighting commitment are justified or if market expectations will shift again.
