At the end of July, the Federal Reserve kept interest rates unchanged for the fifth consecutive time, despite inflation remaining significantly above target and energy prices rising again. The target range for the federal funds rate remained at 3.50% to 3.75%, but the vote shifted from unanimous approval to 9 in favor and 3 against, with Beth Hammark, Neal Kashkari, and Lori Logan advocating for a 25 basis point rate hike. Following the widening policy divergence, the yield on the 30-year U.S. Treasury note rose to 5.237%, a 19-year high, while the 10-year yield also rose to approximately 4.70%. This indicates that market focus has shifted from whether to adjust interest rates next to whether the Fed can control medium- to long-term inflation risks. The key point of this meeting was not that interest rates remained unchanged, but rather that for the first time, three policymakers called for an immediate rate hike. The June meeting unanimously maintained rates with 12 votes, but the expansion of the opposition just six weeks later suggests a change in the committee's assessment of the waiting costs. Hammark pointed out that the longer high inflation persists, the higher the economic cost of bringing it back to target. Kashkari, on the other hand, prefers a gradual tightening approach while observing the paths of inflation and employment, with the core objective of preventing price pressures from solidifying. Their assessment is not simply based on single-month energy prices, but rather on concerns that supply shocks are beginning to spread to broader sectors through transportation, service costs, wage negotiations, and corporate pricing. This divergence means that the debate within the Federal Reserve is no longer about the timing of interest rate cuts, but rather whether the current interest rate of 3.50% to 3.75% is sufficient to restrain aggregate demand. As long as the job market does not deteriorate significantly, those advocating for rate hikes have the fundamental conditions for continued expansion. The US Personal Consumption Expenditures (PCE) price index fell 0.1% month-on-month in June, while the core index rose 0.1%, superficially indicating some easing of short-term price pressures. However, year-on-year data remains high, with the overall index rising 3.7% and the core index rising 3.3%, still significantly short of the 2% policy target. Real PCE expenditures grew by 0.4% during the same period, with nominal PCE expenditures increasing by $65.2 billion, indicating that demand has not contracted to match the rapid decline in inflation. More noteworthy is the quarterly figure. The PCE price index rose 5.1% annualized in the second quarter, higher than the 4.6% in the first quarter; the core index rose 3.4% annualized. Monthly data is affected by a temporary decline in gasoline prices, while quarterly data reflects still relatively strong price momentum. Therefore, the negative growth in June is more likely a temporary buffer from the energy component and cannot yet be considered the starting point of a new round of sustained inflation decline. As of July 31, Brent crude oil prices remained around $88 per barrel, up about 23% for the month. Disrupted shipping routes and supply uncertainty have shifted energy risk from anticipated premiums to actual transportation and storage costs. Monetary policy cannot increase crude oil supply, but it can suppress demand in other sectors, preventing energy price increases from evolving into sustained inflation. Kashkari's reference to the experience of the late 1970s and early 1980s emphasizes the second-round effect, rather than demanding a mechanical replication of historical policies. When businesses believe costs can be continuously passed on, and workers consequently raise wage demands, supply shocks will be supported by demand, ultimately requiring higher real interest rates to break the cycle. Currently, unemployment has changed only slightly, new job creation has largely kept pace with labor force growth, and capital investment and productivity remain resilient. For officials advocating tightening, this means that the cost of a small, early adjustment to employment may be lower than the cost of a concentrated rate hike later. The most important market change after the meeting was not a one-way rise in short-term interest rates, but a significant steepening of the yield curve. Short-term yields remained relatively stable or even declined, while the 30-year yield rose to approximately 5.24%. This combination suggests that the market is not necessarily confident that the Fed will raise rates immediately, but is instead demanding a higher term premium to compensate for the risks of future inflation, insufficient fiscal supply, and inadequate policy response. If the market were simply raising the probability of the next rate hike, the main pressure would typically be concentrated around the two-year mark. The current sell-off is concentrated at the long end, reflecting investors' concerns not about a single 25-basis-point adjustment, but rather about inflation remaining above target for an extended period. The lack of a clear response function in policy communication further amplifies this uncertainty. Therefore, the three dissenting votes act as akin to insurance clauses. They demonstrate to the market that there is still power within the committee to control inflation promptly. However, if energy prices, core service inflation, and consumer demand remain strong simultaneously, dissenting votes alone will be insufficient to stabilize long-term inflation compensation; the gap between policy statements and actual actions will become a core variable in bond pricing.
