Will Yellen's Bond Buyback Force the Fed to Hike Rates? Waller's 'Watch the Ball' Theory Disrupted

U.S. Treasury Secretary Janet Yellen has expanded long-term Treasury buybacks in an effort to reduce government borrowing costs, but this action has introduced a new variable into the Federal Reserve's (Fed) interest rate decisions. Analysts warn that if the Treasury successfully lowers long-term yields, it could ease financial conditions and encourage borrowing—potentially forcing the Fed, which is still battling high inflation, to raise policy rates further.

Fed Chair Jerome Powell has consistently urged investors to base their expectations on economic data rather than fixating on the Fed's interest rate projections. At his July press conference, he used a baseball analogy, calling on markets to "watch the ball, not the umpire," emphasizing that asset prices should freely reflect investor views on the economy, providing clearer signals for the Fed.

However, after Yellen announced the expansion of buybacks for 10- to 30-year Treasuries, the 30-year Treasury yield briefly plunged. Stephanie Roth, chief economist at Wolfe Research, noted this contradicts Powell's goal of having markets reflect fundamental economic conditions. As the Fed prepares to draw more policy signals from market prices, direct Treasury intervention in the long-end bond market risks distorting those signals.

Supporters argue that expanding buybacks is a flexible tool to contain U.S. borrowing costs amid rising government bond yields globally. The actual impact, however, depends on whether the Treasury can sustainably control long-term yields.

Yellen denies that the buyback program affects the Fed's rate decisions. She says Treasury's actions are independent of Fed policy and partly aim to signal that current long-term yields do not reflect underlying U.S. economic fundamentals.

Critics, however, point out that buybacks fail to address the root causes of rising borrowing costs. U.S. public debt has surpassed $40 trillion for the first time, increasing by roughly one-third in less than five years, with no sign of slowing government spending. This is one reason why the 30-year Treasury yield quickly rebounded to pre-announcement levels.

Mary Daly, President of the San Francisco Federal Reserve Bank, remains cautious, stating the measures have just begun and the Fed needs time to assess their full impact before drawing conclusions.

Lower Yields Could Increase Need for Rate Hikes

The Fed is currently in a sensitive policy phase. July meeting minutes show many officials believe further tightening may be needed if inflation does not sustainably cool. The Federal Open Market Committee (FOMC) voted 9-to-3 to keep the federal funds rate unchanged at 3.5%–3.75%, with three dissenters favoring a hike.

Yet post-meeting data indicate slowing economic activity, reducing near-term pressure on the Fed to hike. U.S. July retail sales posted their largest drop in over a year, and core inflation remained relatively moderate.

Kathy Bostjancic, Chief Economist at Nationwide, believes the Treasury's expanded buyback won't alter the Fed's rate outlook. But she notes the irony: just as Powell emphasized the importance of unfiltered market signals, the Treasury is directly influencing prices.

Blake Gwinn, Head of U.S. Rates Strategy at RBC Capital Markets, argues that if part of the Fed's rationale for holding rates steady was that rising long-term yields were already tightening financial conditions, then successfully lowering yields would theoretically increase the Fed's need to hike.

Krishna Guha, Vice Chairman at Evercore ISI, adds that if investors perceive Yellen as managing long-term yields, it becomes harder for Powell to claim market prices independently reflect economic and monetary policy prospects.
