Fixed-Income Stability in a Rising Rate Environment: Evaluating Money Market ETFs as Defensive Tools

As global markets grapple with the dual pressures of rising interest rates and geopolitical uncertainty in 2025, investors are increasingly prioritizing defensive strategies to preserve capital and generate stable returns. Money market ETFs, long regarded as safe havens, have emerged as critical tools in this environment. BlackRock's recent distribution announcements for the iShares® Premium Money Market ETF (PMMF) underscore the fund's role in navigating these challenges while delivering consistent income.

The Macroeconomic Context: Rates, Inflation, and Volatility

The 2025 macroeconomic landscape is defined by elevated short-term interest rates and persistent inflationary pressures. The Federal Reserve's projected 50-basis-point rate cut in Q4 2025 contrasts with a 10-year Treasury yield hovering near 4.5% for much of the year, reflecting lingering inflation concernsUS Economic Forecast Q2 2025^[1]. Meanwhile, tariffs and trade policy shifts have contributed to a core PCE price deflator of 3.6% year-over-year by year-end 2025, complicating the path to the Fed's 2% inflation targetUS Economic Forecast Q2 2025^[1].

In this climate, defensive assets are gaining traction. According to Deloitte, average U.S. tariff rates of 15% through 2025 are expected to slow trade flows and amplify economic volatilityUS Economic Forecast Q2 2025^[1]. Such conditions heighten the appeal of low-risk, liquid investments that can buffer portfolios against downturns.
