Summers warns that slowing the Fed's balance sheet reduction sends an unsettling signal.

On March 21, 2025, former U.S. Treasury Secretary Lawrence Summers expressed concerns in a Thursday interview about the Federal Reserve's recent decision to slow down the pace of quantitative tightening (QT). He noted that this decision might indicate issues with the market's demand for long-term federal debt and suggested that the Federal Reserve might believe "the market's capacity to absorb long-term bonds is limited." Summers found the signal sent by the slowdown in balance sheet reduction worrying and urged investors to be vigilant.

The Federal Reserve announced on Wednesday that starting in April, it would lower the cap on the amount of U.S. Treasury securities not reinvested after maturity from $25 billion per month to $5 billion. Although this decision was mainly due to the federal debt ceiling issue, it also reflected a broader discussion within the Federal Reserve on the appropriate pace of quantitative tightening. To the surprise of some observers, Federal Reserve Chair Powell did not suggest that the pace of quantitative tightening would resume once Congress resolves the debt ceiling issue.

Summers particularly noted that the slowdown in quantitative tightening occurred after a decline in long-term Treasury yields. The benchmark 10-year Treasury yield is currently around 4.23%, down from 4.81% in mid-January. Additionally, as the Federal Reserve's bond purchases create bank reserves, slowing QT could also lead to a shorter overall maturity of U.S. public sector debt. He stated that this implies "the government must shorten the maturity structure of its debt to borrow."

Summers also mentioned that the Federal Reserve might be concerned about a crisis similar to what happened in the UK in September 2022. At that time, the UK government's tax cut plan lacked funding, sparking a market panic that forced the Bank of England to intervene in the bond market to prevent a collapse. He believed the Federal Reserve's actions reflected concerns over "Truss-like risks"—financial crises triggered by unexpected events similar to those in the UK.

Apart from concerns about Federal Reserve policies, Summers criticized a series of moves by the Trump administration, stating they undermined confidence in the rule of law in the U.S. He pointed out that the fiscal policies of the Trump administration, such as significant cuts in federal spending and increased tariffs, have been widely questioned by economists. The current U.S. budget deficit exceeds 6% of GDP, a ratio that is extremely rare in history.

Summers also warned that the actions of the Trump administration have led to multiple lawsuits, including those against the Department of Defense for cutting personnel, expenditures, and loans of federal agencies established by Congress, and the mass deportation of immigrants. He indicated that although the "defying the court order" threshold has not yet been reached, concerns from two months ago have now become a real threat, and investors should remain vigilant.

Finally, Summers reiterated a call he made last year, urging private sector leaders to focus on the government's threats to the rule of law and organize to resist long-term policy changes that could cause significant disruption to the financial system. He stressed that leaders in the business and financial communities should unite because they know how much they depend on the stability of the rule of law.
