Wolfe Research has warned that the recent rise in oil prices linked to the Iran conflict may prompt monetary tightening from some global central banks, a move that could diverge from the Federal Reserve's path and unsettle financial markets.
In a research note, the firm observed that U.S. equity markets have largely ignored the uptick in energy costs. By contrast, longer-term government bond yields and futures-implied central bank rate expectations have moved in line with oil since the onset of the Iran-related tensions. Wolfe Research attributed this disconnect in part to America's relative energy independence compared with other regions.
The note emphasized that higher energy prices are likely to weigh more heavily on economic growth in Europe and Asia because those regions depend more on imported energy. That differential in exposure, the firm said, increases the chance that central banks outside the United States could react differently to the shock.
Over the past month several major central banks have convened policy meetings. Wolfe Research highlighted the possibility of a policy divergence in which some global central banks tighten while the Federal Reserve either holds rates steady or moves toward cuts. Such a split, the firm argued, represents a notable source of market risk.
Wolfe Research drew attention to the Bank of Japan's most recent policy board session, where voting was split 6-3 in favor of holding rates. The firm noted this was the largest member division since Governor Ueda took office in 2023. Wolfe Research suggested the vote may reflect growing pressure within the BOJ to move rates higher, though it said the magnitude and timing of any response remain uncertain.
The research note also cautioned that if the BOJ tightens monetary policy more aggressively than futures markets currently price in - markets that presently imply about two rate hikes - the yen could strengthen substantially versus the dollar. Such a move, Wolfe Research warned, could prompt another unwind of carry trades or generate broader market disruption.
Summarizing the principal risks, Wolfe Research identified two primary threats capable of stopping the ongoing market rally: central bank policy errors, specifically tightening in response to what may be temporary energy-driven inflation; and the prospect of a carry trade unwind triggered by a pronounced appreciation of the yen. These risks, the firm said, are the main channels by which elevated oil prices could destabilize markets.
Summary
Wolfe Research warns that oil-driven price pressures tied to the Iran conflict could lead to tightening by some global central banks, in contrast to the Federal Reserve, creating risks such as a carry trade unwind if the yen strengthens sharply.
- Key points
- U.S. stocks have shown limited response to higher oil prices, while long-term yields and futures-based central bank expectations have aligned with the oil move.
- Europe and Asia face larger growth impacts from elevated energy costs due to greater dependence on energy imports.
- The BOJ's 6-3 hold vote signals potential pressure to tighten, which could disrupt carry trades if policy surprises markets.
- Risks and uncertainties
- Central bank policy error: Tightening in response to temporary higher energy prices could slow growth and stall markets - particularly affecting bond and equity markets in energy-importing regions.
- Carry trade unwind: A substantial yen appreciation versus the dollar could trigger unwinds and market disruption, affecting currency and cross-border funding markets.
