US yields hit 2002 highs as Hormuz oil spike lifts inflation fears and bolsters dollar

The US 10-year Treasury yield reached 5.35% on Wednesday, the highest since April 2002, while the 30-year bond moved to a 24-year high. Brent crude climbed back above $100 a barrel after Iran intensified attacks on tankers in the Strait of Hormuz, adding to inflation concerns that typically lift required bond yields. Treasuries were also sold ahead of Wednesday’s $39 billion auction of new 10-year notes, and the Treasury Department is due to sell new 30-year bonds on Thursday while buying back older debt the same day.

In Europe, flows shifted out of French debt and into German Bunds, keeping the German 10-year yield near 3.5%. The US 10-year therefore offers more than 1.8 percentage points over Germany’s equivalent, a differential that supports demand for dollars ahead of bond purchases. The euro, which makes up about 58% of the US Dollar Index, accounts for roughly three-quarters of the index’s rise. The index has risen for three straight weeks from the 9 September low near 98.60, clawing back Tuesday’s fall around 101.75 after moving up from below 102.00; it tested 102.50 twice and was last near 102.35. The 50-day EMA sits near 100.50 and is rising.

Geopolitical Tensions and Strategies for Energy and Bond Markets

With Brent crude surging past $100 a barrel due to geopolitical tensions in the Strait of Hormuz, we must prepare for sustained upward pressure on energy derivatives. Since roughly 20% of the world’s daily petroleum liquid consumption passes through this vital chokepoint, any further disruptions will likely keep oil prices elevated and fuel global inflation. We recommend that derivative traders focus on long Brent crude futures or call options to capitalize on this geopolitical risk premium.

The US 10-year yield hitting 5.35% and the heavy supply of new government debt mean bond prices are poised to fall further in the coming weeks. Historically, heavy supply pressure, such as the Treasury’s multi-billion dollar auctions this week, pushes yields higher as investors demand a larger discount. We should look to establish short positions on Treasury futures or buy put options on long-term bond contracts to trade this bearish bond trend.

Currency Markets and Dollar Strength Outlook

The widening 1.8 percentage point yield spread between US and German debt is a powerful catalyst for a stronger US Dollar. Because the Euro makes up roughly 58% of the US Dollar Index, the capital flight out of French debt into safer German bunds will continue to depress the Euro. We suggest buying Dollar Index futures or shorting Euro contracts as the greenback looks to break decisively above the 102.50 resistance level.

The Dollar Index’s steady rise above its 50-day moving average near 100.50 confirms a strong bullish trend. Past market data shows that when the Dollar Index recovers from temporary dips to reclaim multi-month highs, it often triggers a prolonged momentum phase. We advise setting defensive stop-losses just below the 101.75 support level while positioning for further upside in USD-denominated derivative instruments.
