Dollar Index Rises to 99.145 as Hot PCE Inflation Lifts Fed Hike Odds

The dollar index climbed 0.24% to 99.145 on Wednesday as hotter-than-expected PCE inflation data nudged expectations higher for a Federal Reserve rate hike ahead of the Jackson Hole symposium.

Investors parsed a fresh batch of U.S. economic data that slightly increased the likelihood of monetary tightening. Currency markets are actively positioning themselves ahead of central bank commentary from Wyoming, seeking clarity on the trajectory of global interest rates.

PCE Inflation and Fed Rate Hike Expectations

The Commerce Department reported that the Personal Consumption Expenditures Price Index increased 3.7% in the 12 months through July. This matched June’s pace and outpaced the 3.6% estimate from economists polled by Reuters. On a month-over-month basis, PCE rose 0.2% against forecasts calling for a 0.1% gain, a notable reversal from the 0.1% decline recorded in June.

Following the data release, markets adjusted their monetary policy bets. CME FedWatch data indicated that markets are now pricing in a 40.1% chance of at least a 25 basis points increase at the central bank’s September meeting. This marks an uptick from the approximate 36% probability assigned before the inflation report. Additional U.S. data painted a mixed but resilient economic picture. The updated reading of second-quarter economic growth came in at 1.5%, unchanged from the initial estimate. Personal income increased 0.4% in July, topping the 0.2% estimate. However, consumer spending, which drives more than two-thirds of economic activity, was unchanged following a 0.3% increase in June.

FX Strategists Urge Caution Amid Competing Narratives

Despite the dollar’s upward trajectory, market analysts urge caution against aggressively chasing the rally. “Overall, because the headline was warm enough to prevent a dovish victory, those details weren’t really strong enough to hand the hawks a clear win, so I wouldn’t chase the rally at all,” said George Vessey, lead FX and macro strategist at Convera in London.

Vessey highlighted the complex crosscurrents currently dictating currency flows. “But I wouldn’t fade it aggressively either, we’ve got loads of competing narratives driving FX at the moment, particularly the dollar, haven’t we, so it’s hard to have a strong conviction in either direction right now,” he added.

Global Central Bank Divergence and Currency Moves

The Federal Reserve is not the only central bank navigating inflationary pressures. European Central Bank board member Isabel Schnabel stated that interest rates must rise further, citing the ongoing conflict in the Middle East and a robust euro zone economy as upside risks to inflation. Her comments followed a Reuters report that ECB policymakers are prepared to raise rates at their next September meeting to contain the side-effects of the Iran war, though they have little appetite to signal further tightening beyond that.

Meanwhile, major currency pairs reflected the dollar’s broad strength. The euro slipped 0.18% to $1.1653. Sterling fell 0.41% to $1.3593, putting it on track for its biggest daily drop since July 23. The Japanese yen weakened 0.13% against the greenback to 159.37 per dollar. The Canadian dollar also weakened 0.24% to C$1.387 per dollar, reversing slight gains from the previous day. This drop followed Ottawa’s decision to place retaliatory tariffs on about $20 billion worth of U.S. annual imports and roll out aid for businesses after trade talks with the U.S. collapsed over the weekend.

Jackson Hole Focus and Treasury Dynamics

Attention now shifts to the annual Jackson Hole symposium. Federal Reserve Chairman Kevin Warsh will deliver his debut speech on Friday, though many market participants remain skeptical that he will offer explicit policy guidance. Goldman Sachs chief U.S. economist David Mericle noted that Warsh is “unlikely to provide policy guidance.” However, Mericle expects the chair to “reiterate his commitment to the 2% inflation target, expand on the rationale behind his approach to Fed communication, and offer thoughts on some bigger picture topics such as productivity growth or shocks to the global economy that he alluded to at his last press conference.”

Boston Fed President Susan Collins added to the hawkish chorus on Tuesday, stating the central bank will need to raise interest rates soon unless coming data shows a continued decline in inflation. She noted that elevated inflation has become a “pervasive” concern for businesses and households.

The dollar’s recent strength follows a stumble late last week when U.S. Treasury Secretary Scott Bessent announced the Treasury would double the size of quarterly repurchases of longer-dated bonds. This sparked concerns that a more direct strategy to mitigate rising borrowing costs could lead to a debasement of the dollar. However, Barclays analysts noted in a Tuesday research piece that their month-end rebalancing model indicates a moderate dollar selling signal against all major currencies by month-end.

What Happens Next

Traders will closely monitor Federal Reserve Chairman Kevin Warsh’s Jackson Hole address for any subtle shifts in rhetoric regarding the 2% inflation target or balance sheet management. If the PCE inflation trend continues upward, the probability of a September rate hike will likely solidify above the current 40% threshold, providing further tailwinds for the dollar index. Conversely, any dovish surprises from Jackson Hole or renewed Treasury intervention in the bond market could rapidly alter the dollar’s trajectory. Investors should also watch the ECB’s September meeting, as the divergence between Fed and ECB policy paths will ultimately dictate the euro’s direction against the resurgent greenback.
