Market Substitutes for Fed 'Rate Hike'! Soaring US Treasury Yields Become Warsh's New Tool for Tightening?

US Treasury yields have risen sharply in recent months, leading market participants to believe this movement is effectively achieving the same tightening impact as an actual rate hike by the Federal Reserve (Fed). This means the Fed could achieve its goal of tightening financial conditions without needing to raise interest rates directly. The key driver behind this yield surge is the consistent hawkish messaging from Federal Reserve Chair Kevin Warsh.

The June Consumer Price Index (CPI) showed its first month-on-month decline since 2020, briefly easing market concerns. As a result, positions betting on a rate hike this month were quickly unwound for profit. However, Warsh immediately cooled expectations during his congressional testimony, emphasizing that a single month of lower inflation does not mean the battle against inflation is over.

Federal Reserve Bank presidents Jeff Schmid of Kansas City, Lorie Logan of Dallas, and Beth Hammack of Cleveland have also echoed similar views. While market expectations for a July rate hike have faded, there is growing consensus that the Fed will raise rates by 25 basis points in either September or October. A rate hike by year-end has become the prevailing market consensus.

Despite the temporary relief from June's CPI data, markets remain cautious about the future trajectory of inflation.

The collapse of the ceasefire agreement between the US and Iran has driven oil prices higher again. Meanwhile, although concerns about a tech stock bubble are emerging, massive capital expenditures related to artificial intelligence (AI) continue to fuel economic momentum.

For the past five years, US inflation has remained stubbornly above the Federal Reserve's 2% target. This persistent trend makes it difficult for markets to assume the Fed will pivot to an easing stance anytime soon.

Ed Al-Hussainy, portfolio manager at Columbia Threadneedle, stated bluntly: "If the Fed stays on hold, no one can guarantee inflation will automatically fall back into the 2% to 2.5% range."

He believes the Fed should now have more confidence to raise rates rather than overly worrying about downside economic risks. He is currently positioning for long-dated bonds to outperform short-dated bonds, preparing to benefit from a potential hawkish shift by the Fed.

The economist team at Bank of America expects the Fed to raise rates in September, October, and December. In a report issued after the CPI release, the bank noted that inflation remains far above target and that several more similar data points would be needed before adjusting their current outlook.

Notably, since late February, the two-year US Treasury yield has surged over 75 basis points, approaching 4.2%—well above the Fed's current policy rate range of 3.5% to 3.75%.

Analysts believe this yield increase has already tightened financial conditions by pushing up mortgage and loan costs, effectively cooling the economy. In a sense, the bond market is already shouldering part of the Fed's policy burden.

Jeffrey Sherman, Deputy CIO at DoubleLine, pointed out that bond markets have historically led Fed policy moves, as seen in the forward pricing of federal funds rates. The most significant change now, he noted, is that markets are no longer uniformly pricing in rate cuts, as they did over the past three years, but are beginning to reflect the possibility of rate hikes over the next 12 months.

Sherman described this as a stark contrast to previous policy cycles. In the past, markets would immediately price in rate cuts as soon as the Fed announced the end of a hiking cycle—even though cuts often failed to materialize. Today’s market sentiment has shifted toward the possibility that the Fed might hike rates at some point in the next year.

In his view, this means Warsh may not need to act urgently. With the yield curve now positively sloped and policy rates below yields on other maturities, the market has already done part of the Fed’s job. Warsh could therefore afford to wait and see.

"The bond market is doing its job," he concluded, "continuously sniffing out the latest data trends."

Hawkish but Flexible: Warsh's Deliberate Ambiguity

Warsh, who took office as Fed Chair two months ago, has consistently prioritized inflation control since his appointment. During his first post-meeting press conference last month, he repeatedly emphasized the necessity of price stability. Last week, during his congressional testimony, he reiterated that the June CPI data does not signify the end of the inflation fight.

However, Warsh has not given a clear commitment on the timing of a rate hike. Instead, he has tended to downplay the Fed’s forward guidance on interest rate prospects, arguing that overly clear guidance could trap policymakers in a passive position and limit their ability to respond flexibly to changing conditions.

Fed officials have now entered their usual pre-meeting quiet period ahead of the two-day meeting starting July 28, meaning the market will temporarily lose access to new policy signals.

Since the Fed’s last rate cut in December last year, it has held rates steady for several consecutive months. At the time, the labor market rebounded from a February low, and the Trump administration launched a military operation against Iran, reigniting inflation concerns. As a result, the widely expected restart of the easing cycle failed to materialize.

Warsh has repeatedly emphasized his commitment to defending the Fed’s political independence and will not yield to political pressure from President Trump, who has called for rate cuts.

Market Views Diverge: Caution Remains

Although rate hike expectations dominate market sentiment, some institutions remain relatively cautious about the timing and pace of actual Fed action.

Chi Chen, co-manager of BlackRock’s $18 billion Total Return Fund, noted that the market’s pricing of the Fed’s policy path is more hawkish than she initially expected—assuming her team’s outlook for inflation cooling and economic slowdown in the second half holds true.

She believes the Fed may maintain a hawkish posture, waiting for data to truly turn mild before making decisions. Chen’s team is currently leaning toward adding exposure to intermediate- and short-term bonds, believing valuations have become more attractive after a wave of sell-offs triggered by the Iran conflict.

Sherman also remains cautious about the threshold for a September rate hike, believing that "a large amount" of supportive data would be needed to prompt the Fed to act, especially given the upcoming election and ongoing political pressures.

Al-Hussainy expressed reservations as well, stating it is not the time to take aggressive risks. Until the Fed’s policy path becomes clearer, avoiding heavy bets on interest-rate-sensitive positions may be the most prudent strategy for now.
