Dollar Stays Near 18-Month High on Mideast, CPI Focus

TL;DR: The dollar index sat at 102.14 on Monday, close to the 18-month high it hit last week, as Middle East fighting and a US inflation report due this week kept investors cautious, according to Reuters. Traders put an 81% chance on the Fed holding rates this month. Oil stayed above $103 a barrel.

On the submarine, I signed off on QA jobs only after the check was done, never on the first reading. A Monday morning in Asian trading is a first reading. It matters to you if you own private funds, because a currency move like this changes what overseas holdings are worth on your statement and what a leveraged deal costs to finance.

What happened to the dollar on Monday?

The dollar index, which measures the greenback against a basket of six currencies, was slightly down at 102.14 in early Asian trade, Reuters reported. That's still not far from the 18-month peak it reached last week. Against the yen, the dollar was down 0.14% at 158.160.

The euro is the weak side of the trade. After a fifth straight week of losses, it rose nearly 0.1% to $1.121, as investors worried about France's fiscal health ahead of the 2027 presidential election.

The positioning data tells me the move has real money behind it. Weekly data from the US markets regulator shows bullish dollar bets rose to around $36 billion in the week to October 7, from $8.4 billion three weeks earlier, largely at the expense of the euro, Reuters reported via Euronext.

Why is the Middle East conflict moving currencies?

Oil is the link. Brent crude was down 1% at $103.55 a barrel, according to Reuters, but that follows swings after Yemen's Iran-backed Houthis stepped up strikes on Saudi Arabia and two tankers were attacked over the weekend, per CNBC.

Brent futures sit nearly 45% above where they were before the war started, with some physical markets at double those levels. I wouldn't count on diplomacy to change that soon. Iran confirmed receiving a US peace proposal through intermediaries, but analysts quoted by Reuters said "we do not expect a breakthrough this week."

What does the inflation data change for the Fed?

The Fed raised rates last month for the first time since 2023, and markets are watching data to judge whether it moves again, according to Reuters. Traders now price an 81% chance of the Fed standing pat this month, up from 51% a month earlier, per the CME FedWatch tool.

Our dollar index piece from October 6 put the odds of an October hike above 70%, citing fxstreet.com. The Reuters pricing now points to a hold. That's why I read this week's inflation report as the swing factor, not the dollar level itself.

Four of these rows are prices. The Fed odds are traders' guesses, and one data release can flip them.

What does a strong dollar mean for accredited investors?

If you hold private funds with overseas assets, a stronger dollar shrinks what those holdings are worth when translated back into dollars. If you're buying foreign assets or funds with currency exposure, it lowers your entry cost but adds the risk that the move reverses. No source I found measures either effect for private markets, so this is my reading of how currency translation works, not a measured result.

Oil above $100 also feeds inflation worries, and higher rates raise the cost of capital for every leveraged deal you evaluate. Our guide to gold, commodities and real assets as inflation hedges covers the tools people reach for here, with their own downsides. Rising rates also strain lenders: our look at private credit's redemption backlog shows what that pressure looks like when investors want out.

Downside first. Before you ask what the dollar's strength might add to your returns, ask which of your holdings it could quietly subtract from.

Common mistakes when the dollar jumps

The first mistake is treating an 18-month high as a signal to act. It describes where the dollar has been, and Reuters itself notes that markets are waiting on a data release that hasn't happened yet.

The second is ignoring currency exposure you already own. It tends to sit in a fund's footnotes, and you only need one afternoon to find it. The third is reacting to the Fed odds as if they were a decision. A rise from 51% to 81% still leaves a one-in-five chance of something else.

FAQ

Why is the dollar near an 18-month high? Reuters ties it to the Middle East conflict keeping investors cautious, ahead of US inflation data later this week. Traders have also added bullish dollar bets, largely against the euro, which has fallen for five straight weeks.

Will the Fed raise rates this month? Markets price an 81% chance the Fed holds, up from 51% a month ago, per the CME FedWatch tool as reported by Reuters. The Fed raised rates last month for the first time since 2023. This week's inflation data could shift those odds.

Does a strong dollar hurt private investments? It can reduce the dollar value of foreign-currency assets and funds with overseas exposure. The effect depends on each fund's holdings and hedging. Check the fund's currency policy in its documents.
