The US dollar continues to hold a strong position near its highest level in two weeks, benefiting from a clear shift in the global risk landscape. Military escalation in the Middle East has pushed oil prices higher again, bringing inflation concerns back into focus and influencing the pricing of interest rates and bond yields. This has translated directly into stronger demand for the US currency. The Dollar Index climbed to 99.79, its highest level since August 17, while the euro slipped to 1.1576, indicating that yield differentials between the United States and other major economies are becoming increasingly influential in currency markets.
Support for the dollar is not coming solely from defensive demand linked to geopolitical tensions. A broad repricing of the US monetary policy outlook is also playing a major role. Treasury yields have resumed their sharp rise, with the 10 year yield moving above 4.80%, while markets are increasingly pricing in another Federal Reserve rate hike at the September meeting. Higher yields make dollar denominated assets more attractive while placing additional pressure on equities and other risk assets, particularly technology and growth stocks that are more sensitive to rising financing costs.
Oil remains one of the most important factors influencing markets. Brent crude is trading above $95 per barrel, while West Texas Intermediate is hovering near $91 following a strong rally driven by renewed confrontation between the United States and Iran. If prices remain at these levels, higher energy costs could feed into inflation over the coming months, reducing the scope for monetary policy easing. For this reason, markets are increasingly treating tensions around the Strait of Hormuz as a monetary issue as well as a geopolitical one, because any further disruption to shipping or energy supplies could quickly affect inflation and interest rate expectations.
At the same time, global bond markets are facing a broad selloff. US yields have risen across the curve, with the two year yield reaching 4.354%, the 10 year yield climbing to 4.780%, and the 30 year yield moving above 5.27%. The pressure has not been limited to the United States. German and French yields have reached their highest levels in years, while Japan’s 10 year government bond yield has reached 3% for the first time in nearly three decades. These moves suggest that investors no longer view inflation as a purely US problem, but rather as a global risk that could force central banks to keep interest rates elevated for longer.
The Federal Reserve has also become more explicit in its communication. Comments from Michael Barr have increased market sensitivity to inflation data after he indicated that persistently high inflation could justify another rate increase. Market expectations for a September hike have risen to between 66% and 68%, compared with roughly 30% to 40% before the Jackson Hole speech. This repricing has taken place despite weaker than expected data from job openings and the ISM manufacturing index, suggesting that investors are currently more focused on inflation risks than on slowing growth.
The PCE price index at 3.7% and core PCE at 3.3% help explain why the Federal Reserve continues to maintain a restrictive stance. Inflation has fallen substantially from its previous peak, but it remains well above the 2% target, while higher oil prices are making the outlook more complicated. Upcoming employment and inflation figures will therefore be critical. A clear deterioration in the labor market could encourage the Fed to wait, while stable employment combined with persistent inflation could provide enough justification for another rate increase in September or December.
US equities have already started to reflect this shift. S&P 500 futures have declined, while Nasdaq 100 futures have posted larger losses, a typical reaction in an environment of rising interest rates and bond yields. Technology stocks tend to face greater pressure when discount rates rise because a significant portion of their valuations depends on future earnings. If the 10 year Treasury yield remains near 4.8% or moves above that level, growth sectors could face further valuation pressure, while defensive sectors and assets with more stable cash flows may become relatively more attractive.
In currency markets, the New Zealand dollar has been among the biggest losers despite the Reserve Bank of New Zealand raising its policy rate to 2.75%. The reaction shows that investors were less focused on the rate increase itself and more concerned with the accompanying guidance, which was viewed as less hawkish than expected. NZD/USD fell to 0.5844, while the British pound declined to 1.3495 and the Australian dollar slipped to 0.7133. The strength of the US dollar in this environment reflects superior US yields and diverging central bank policies more than simple safe haven demand.
The Japanese yen remains under significant pressure near 160 per dollar despite expectations that the Bank of Japan will raise interest rates. Higher Japanese bond yields have so far failed to reverse the currency’s weakness on a sustained basis, particularly while oil prices remain elevated. This is a negative factor for an economy heavily dependent on energy imports. The coordinated intervention carried out in July temporarily reduced pressure on the yen, but its impact has gradually faded. Another intervention may prove more difficult unless oil prices decline or tensions around the Strait of Hormuz ease.
The broader market picture is now being shaped by three main forces: oil prices, bond yields and Federal Reserve policy. Oil remaining at elevated levels will keep inflation concerns alive, while US yields near recent highs are likely to support the dollar and weigh on equities, gold and other risk sensitive assets. Upcoming employment and inflation data could alter this balance, but for now market conditions continue to favor a stronger dollar and higher yields, while interest rate sensitive assets remain under pressure until clearer signs emerge that inflation is cooling or geopolitical tensions are easing.
