USD/JPY tests 160.73 as hawkish Fed shifts FX outlook

USD/JPY pushed toward 160.73 on Thursday after the Federal Reserve's first meeting under Chair Kevin Warsh delivered a hawkish surprise that repriced the entire US rates outlook, widening yield differentials in favor of the dollar and reviving intervention risk from Japan's Ministry of Finance.

The pair climbed as high as 160.73 in the immediate aftermath of Wednesday's decision, a level that previously triggered BOJ intervention in late April. While the Fed held its benchmark rate steady at 3.5 percent to 3.75 percent — the fourth consecutive hold — the accompanying Summary of Economic Projections revealed a committee far more divided on the path ahead than markets had anticipated.

Nine of 18 FOMC members now see rates rising this year, with six projecting at least two hikes and one seeing three, according to the dot plot released Wednesday. Warsh, who declined to submit his own projections, stripped forward guidance from the statement entirely, telling reporters "we cannot have a very significant effect on particular prices" while doubling down on the Fed's commitment to price stability.

"The bigger story from the latest Fed meeting may not be what it means for US interest rates — it may be what it means for the yen and carry trades," said a note from forex analysts at a major bank. "If the underlying driver is a widening interest rate differential in favor of the United States, intervention may do little more than provide better levels for bullish investors to buy back in."

The Fed's Inflation Pivot Reshapes the Dollar Outlook

The June statement marked a stark departure from the Powell era. Where previous FOMC communications balanced inflation against labor market risks, Warsh's statement focused almost exclusively on price stability, noting inflation remains elevated "in part" due to supply shocks while implying domestic factors are also at play. The phrase "The Committee will deliver price stability" was widely interpreted as the most hawkish language possible without an actual rate hike.

The updated economic projections reinforced the message. Inflation forecasts were revised sharply higher for this year and next, despite mounting evidence of labor market cooling. The household survey has shown unemployment edging higher and wage growth moderating to 3.4 percent, yet the Fed's median projection still sees the economy growing above trend — sustaining enough demand to keep inflationary pressures alive.

Markets responded immediately. The two-year Treasury yield jumped 9 basis points to around 4.13 percent, while the benchmark 10-year yield ticked up 2 basis points toward the key 4.5 percent level. Fed funds futures now price a full rate hike by October and close to two hikes by the middle of next year.

Equities sold off as rate-sensitive sectors repriced. The S&P 500 fell 0.55 percent to 7,470.37, the Dow Jones Industrial Average slipped 0.08 percent to 51,956.82, and the Nasdaq Composite dropped 0.56 percent to 26,233.29.

Japan's Intervention Dilemma Intensifies

For Japanese authorities, the Fed's hawkish shift creates an uncomfortable calculus. USD/JPY now trades at levels that previously forced the Ministry of Finance to instruct the BOJ to intervene, and the widening rate differential provides fundamental support for further upside.

The pair has been grinding higher within a shallow uptrend established in mid-May, attracting bids on dips toward the trendline. Above 160.73, the next target is the 2024 high at 161.95. A break and hold above that level without the usual torrent of verbal intervention from MOF officials could embolden bulls to establish fresh longs.

If intervention does materialize, key support levels include the 50-day moving average at 157.92 and the intersection of the Liberation Day uptrend, 200-day moving average, and support at 155.65. The bearish divergence between price and the 14-day RSI provides a minor warning for bulls, though such signals have proven unreliable during intervention-driven moves.

EUR/USD, meanwhile, is teetering above 1.1500 after briefly trading through the level following the Fed. The euro's inability to hold above 1.1600 earlier this week leaves it vulnerable to a retest of the March lows at 1.1412, with the 1.1400 figure representing the next major support.

The broader implication for currency markets is that the Fed under Warsh may operate with a fundamentally different reaction function than under Powell. If the new chair follows through on his pledge to make policy more data-dependent and markets believe the hawkish messaging, the dollar could remain bid across the board — leaving Japan's MOF with a choice between accepting a weaker yen or intervening repeatedly to slow the move.
