Kevin Warsh was sworn in as the 17th Chair of the Federal Reserve on May 22, marking what he has described as a “regime change” in how the central bank operates and communicates. For mortgage investors, the implications of this shift are significant. Warsh has been explicit and consistent on one point in particular: he does not believe in forward guidance. Understanding what that means requires a brief look at how Fed communication has evolved over the past four decades.
From Greenspan’s Fog to Powell’s Transparency
Alan Greenspan, who chaired the Fed from 1987 to 2006, elevated deliberate ambiguity to an art form. His carefully crafted statements were intentionally opaque, designed to prevent markets from reacting prematurely to anticipated policy changes. Greenspan once quipped that if he had seemed especially clear, he had probably misspoken. This communication style, widely dubbed “Fedspeak,” treated ambiguity as a monetary policy tool in its own right.
That began to change in the early 2000s. In 2003, the Federal Open Market Committee (FOMC) started incorporating explicit signals about the future path of interest rates into its post-meeting statements. Ben Bernanke, who succeeded Greenspan in 2006, then codified transparency as a core institutional principle. During the 2008 financial crisis, with rates near zero, Bernanke used forward guidance as a policy tool, publicly committing to keeping rates low for an extended period to anchor long-term expectations. Janet Yellen deepened that framework, and Jerome Powell extended it further, holding press conferences after every FOMC meeting and publishing the now-famous dot plot four times per year.
Warsh’s Critique: A Crisis Tool Overstayed Its Welcome
Warsh’s objection to forward guidance is both philosophical and practical. In an April 2025 lecture to the IMF, he argued that “moving markets with rolling Fed incantations is tempting, but unhelpful to the Fed’s deliberations, and ultimately, to its mission.” At the core of his critique is a belief that forward guidance was designed for extraordinary circumstances and has no proper role in a normalized rate environment. By signalling policy intentions too far in advance, the Fed effectively binds itself to a predetermined path, limiting its flexibility to respond to changing economic data.
The dot plot, which shows where each FOMC member expects rates to go, is a particular point of concern for Warsh. In his view, it commits the Fed to a forecast that markets then trade as a promise.
What Changes and What It Means for Mortgage Markets
Warsh has signalled that he intends to retire or substantially reform the dot plot and reduce the frequency of post-meeting press conferences. In practice, this would mark a partial return to the Greenspan model, though without the same degree of deliberate opacity. Rather than relying on projected rate paths, the Fed would communicate primarily through its policy actions and post-meeting statements.
For U.S. mortgage investors, this is significant in two ways. First, rate volatility is likely to increase as markets lose the anchor provided by the dot plot. Without a published rate path to guide expectations, markets will react more directly to each economic data release, increasing volatility at the front end of the yield curve and making hedging more complex.
Second, Warsh is widely viewed as more hawkish on the balance sheet than his predecessors, with a preference for a faster runoff of mortgage-backed securities (MBS). That could keep structural pressure on MBS spreads regardless of what happens to the policy rate.
For Canadian mortgage investors, it also means increased rate volatility, as the bond market is likely to be more volatile. Investors should prepare for a period in which the Fed speaks less and acts with more deliberate ambiguity. The era of forward guidance age may be coming to an end.
