Stock Market Surge May Be an "Invisible Driver" of Core Inflation
Recently, Bank of America issued a warning in its latest report, suggesting that the continuous rise in U.S. stocks not only boosts investor wealth but could also inadvertently push up U.S. inflation levels. The report notes that as financial markets strengthen, the rise in stock prices will be directly reflected in the PCE price index through portfolio management fee mechanisms, contributing to core inflation.
Data shows that as the U.S. stock market continues to rebound, fees in the portfolio management category will increase in tandem with fund asset values, creating upward pressure on this category's price index. It is predicted that in June alone this category could contribute at least 6 basis points to core PCE inflation, and this driving force may persist in the coming months.
Mechanism of Portfolio Management Fees
For a long time, portfolio management fees have been closely tied to stock market performance as part of financial services. Bank of America highlights that management fees are linked to the scale of fund assets; thus, an increase in stock market value directly raises the total assets under management, elevating the price index of the portfolio management subcategory and affecting the core PCE measure.
In previous months, market volatility had dampened the effect of this category on core inflation. However, with the recent rebound in U.S. stocks, this "dampening" has now reversed into a driving force, introducing a new source of inflationary pressure.
Specifically, the weight of portfolio management in core inflation is about 1.7%. Although the proportion is small, in the context of core PCE's difficulty in declining, even a slight push can have a substantial impact.
Inflation Rise Could Affect Future Fed Policy Space
Bank of America's report states that with both tariff policies and stock market rises pushing inflation expectations, U.S. core PCE may continue to rise in the coming months, potentially reaching a peak of 3.2% in November. This could pose more constraints on the Fed's future rate-cutting room.
The Fed is currently closely monitoring economic and inflation trends, striving to achieve a balance between inflation receding and economic stability in a high-interest-rate environment. However, if the stock market continues to strengthen, driving up service inflation, it may limit the Fed's window for early monetary policy easing.
Some market participants believe this implies a more complex path for future monetary policy. Investors need to pay attention to changes in inflation indicators like PCE and CPI to adjust their positions and risk exposures across different asset classes.
Investors Should Watch Inflation and Market Linkage Risks
Currently, the rise in U.S. stocks, while boosting market risk appetite, may also bring "reverse risks"—namely, the increase in asset prices themselves can drive up management fees, further exacerbating inflation levels. This will affect capital flows and pricing logic in the bond, precious metal, and foreign exchange markets.
Analysts suggest that while enjoying the wealth effects brought about by the rising stock market, investors should closely monitor Fed policy statements and the monthly trend of core PCE to avoid market volatility triggered by rising inflation expectations.
Cycle of Asset Prices and Inflation
Bank of America's report emphasizes a frequently overlooked core view: the rise in stock markets reflects not only economic recovery and ample liquidity but also may drive up core inflation through the mechanism of portfolio management fees, creating a cycle of rising asset prices and inflation levels.
In a global economy still fraught with uncertainty, this potential driver of U.S. core inflation deserves investors' close attention to adjust risk management strategies and asset allocations in a timely manner, maintaining a steady investment pace in a high-volatility environment.
