Inflation data reinforced that shift, although it did not eliminate the Fed’s inflation problem. July consumer-price inflation rose 3.4% year over year, down from 3.5% in June, while core CPI slowed to 2.5%. July producer prices were unchanged, missing expectations for a 0.2% increase.

Consumer demand also looked less robust: July retail sales dropped 0.6% after a 0.2% increase in June. Taken together, the figures suggested that employment, spending and price pressures were losing momentum. The market implication was straightforward: fewer expected rate increases mean a smaller prospective yield advantage for the dollar.

Why currencies outside the US benefited

Foreign-exchange markets react not only to economic growth but also to relative interest-rate expectations. When traders expect US rates to rise less than previously thought, they often reduce long-dollar positions and look for opportunities in currencies whose central banks may remain relatively less dovish.

Yen: supported by lower US yields, limited by weak Japanese demand

The yen can benefit if softer US data narrow the US–Japan yield gap. However, Japan’s own growth data complicate the picture. Second-quarter GDP expanded at a 1.1% annualized rate, below the 2.0% consensus forecast, while private consumption was flat. Reuters reported that the weak result was not expected to change the near-term outlook for a Bank of Japan hike.

That combination creates two competing forces: lower expected US rates can support the yen, but fragile domestic demand may limit expectations for faster Japanese tightening. The yen also remains highly sensitive to US Treasury yields and intervention concerns around ¥160 per dollar.

Canadian dollar: helped by oil and a relatively firm inflation backdrop

The Canadian dollar has two potential sources of support in this environment. Broad US-dollar weakness improves the exchange-rate backdrop, while higher oil prices can help an energy-exporting economy relative to oil importers.

Canada’s July headline CPI was reported at 2.9%, up from 2.8% in June, while core measures remained close to 2%. The Bank of Canada had held its policy rate at 2.25% and said headline inflation could ease if oil prices and gasoline margins declined. That leaves the Canadian dollar sensitive to whether higher energy prices are viewed as temporary or persistent: a lasting oil shock could support the currency through trade flows but also complicate monetary policy.

Australian dollar: exposed to both dollar weakness and global risk appetite

The Australian dollar may gain when the US rate outlook becomes less hawkish, particularly if investors become more willing to hold higher-yielding currencies. But it is more vulnerable than the Canadian dollar to a broad risk-off reaction caused by Middle East escalation or a sharp rise in global energy costs. The result is likely to be selective rather than a uniform rally across risk-sensitive currencies.

Indian rupee: initial dollar relief, but oil is a major counterforce

A weaker dollar can reduce pressure on the rupee and improve the backdrop for portfolio flows. Higher oil prices work in the opposite direction because India is an oil importer: a sustained increase in crude costs can enlarge the import bill and weaken the currency. The rupee could therefore benefit from softer Fed expectations only if the oil shock remains contained.

The oil shock creates a second, opposing dollar channel

The Strait of Hormuz crisis limits the durability of a purely bearish-dollar view. Shipping traffic through the strait reportedly fell to six vessels from a 10-day average of about 11. Brent crude settled at $88.52 per barrel on August 14 as traders assessed tanker attacks, stalled peace efforts and the risk of prolonged disruption.

Iran’s warning of a more offensive posture added to the possibility of a higher oil-risk premium. For currencies, the effects are uneven:

• Higher oil can be relatively supportive for the Canadian dollar.
• It is generally negative for oil-importing currencies such as the Indian rupee.
• A severe escalation can become positive for the dollar if investors move into US assets for liquidity and safety.

This explains why the dollar can fall on softer domestic data even while geopolitical developments remain capable of driving it sharply higher.

Treasury yields may slow the dollar’s decline

Elevated Treasury yields preserve some of the dollar’s carry appeal. They also matter for the Fed’s reaction function: if oil prices push headline inflation and inflation expectations higher, officials may be reluctant to endorse market pricing for no further hikes—or for only a limited amount of additional tightening.

That risk has precedent in the supplied market reporting. During an earlier escalation in Gulf hostilities, the dollar was supported by both geopolitical demand and hawkish Federal Reserve commentary. A similar combination of higher yields and risk aversion could interrupt the current dollar downtrend.

What to watch next

The next policy communications will determine whether markets treat the recent data as the start of a sustained slowdown or as a temporary soft patch.

• The July FOMC minutes: Investors will look for the balance officials placed between weaker activity and still-elevated inflation.
• The August 27–29 Jackson Hole symposium: A message that oil-related inflation is temporary and underlying disinflation is continuing would reinforce the dollar’s downside. Emphasis on persistent inflation or the need to preserve room for further tightening would support Treasury yields and the dollar.
• Oil and Hormuz traffic: Further shipping disruption or a broader conflict would raise the risk of inflation, a global risk-off move and renewed dollar demand.
• Japan and Canada data: Evidence of stronger domestic demand in Japan could add to yen support, while persistent Canadian inflation or oil-driven price pressure could affect expectations for the Bank of Canada.

Bottom line

The dollar fell because markets repriced the US interest-rate path after weak payrolls, cooling consumer and producer inflation, and declining retail sales. The immediate result was less confidence in a September Fed hike and a smaller expected US yield advantage, supporting several major and emerging-market currencies.

The outlook remains two-sided. A continued run of soft US data and a reassuring Fed message would favor a weaker dollar. But high Treasury yields, persistent inflation and another Hormuz escalation could quickly revive demand for the US currency.
