The US dollar held close to an 18-month high on 12 October as investors balanced safe-haven demand from the Middle East conflict against an important week for US inflation data. The dollar index was near 102.16 in early Asian trading, according to Reuters.
Why the dollar remains supported
Two forces are reinforcing each other. First, geopolitical stress tends to favour the dollar because of the depth of US markets and its role in global funding. Second, elevated Treasury yields increase the relative return on dollar assets. The 10-year yield recently traded around levels last seen in 2002, while markets reassessed the path of Federal Reserve policy.
Energy is the link between the two stories. Brent crude traded above $100 a barrel after attacks on tankers and escalating tensions involving Saudi Arabia and Yemen’s Houthis. Higher oil prices can lift inflation expectations, reduce the scope for rate cuts and weaken the trade balances of energy-importing economies—all of which can support the dollar.
The inflation test
Upcoming US consumer-price data will help determine whether the dollar’s yield advantage can persist. A stronger core reading would reinforce expectations that policy must remain restrictive. A softer result could lower short-term yields and encourage investors to take profits on crowded long-dollar positions.
Monday’s moves should be interpreted cautiously. Japanese markets were closed for a holiday, reducing Asian liquidity, and the dollar index was slightly lower on the day despite remaining near its recent peak.
Cross-asset implications
Equities: a stronger dollar can pressure overseas revenue when translated back into dollars and can tighten global financial conditions, especially for emerging markets with dollar liabilities.
Bonds: persistent inflation and higher energy costs would keep upward pressure on yields and duration risk. A weaker inflation print would favour a partial reversal.
Commodities: the usual inverse dollar relationship may be less reliable while oil itself is driving inflation and haven demand.
Bullish and bearish dollar scenarios
The bullish case combines sticky inflation, elevated oil prices and continued geopolitical stress. The bearish case requires clearer disinflation, lower Treasury yields or credible diplomatic de-escalation. Because several of these catalysts can reverse quickly, the current level argues for scenario analysis rather than extrapolating a one-way trend.
What investors should monitor
- Headline and core US CPI, especially shelter and services components.
- Two- and 10-year Treasury yields after the data.
- Brent crude and evidence that shipping disruptions are easing or worsening.
- Whether the dollar breaks above its recent high on broad participation rather than thin liquidity.
