Dollar rallies as oil prices jump and AI fears knock markets

[LONDON/SINGAPORE] The US dollar rose to a two-week high on Monday (Sep 14) as conflict in the Middle East pushed up oil prices and sent investors towards the safe-haven currency, weighing particularly on the recently buoyant yen.
Warnings from frontier company CEOs about the possible dangers of AI weighed on stocks and also boosted the dollar, while rising bets on a Federal Reserve rate hike on Wednesday supported the US currency.
The US dollar index, which tracks the currency against six major peers, was last up almost 0.4 per cent after earlier touching 99.6, its highest since September 2.
The euro fell to a one-month low of US$1.153 and was last down 0.4 per cent, while the British pound fell 0.3 per cent to US$1.35.
A jump in oil prices unnerved investors and sent global bond yields back towards multi-year highs, with Brent crude up 3 per cent to US$108 a barrel.
Houthi strikes on the world’s biggest exporter Saudi Arabia, which came after the kingdom shut down its main pipeline for bypassing the Strait of Hormuz, added to concerns about energy supplies.
Diplomacy over the US-Iran war appeared to falter, with a meeting between Teheran and other Gulf governments postponed. Attacks on ships in the region compounded supply worries.
“Gulf developments remain concerning, and some AI-related headlines are further weighing on equities – an environment where the dollar should remain supported,” said Francesco Pesole, currency strategist at ING.
The Japanese yen was a notable faller, giving up some of its recent sharp gains that have been driven by rising bets on Bank of Japan rate hikes.

The key question for markets this week is whether the US Fed will hike interest rates on Wednesday in response to the jump in energy prices that has pushed diesel to record highs and helped lift underlying inflationby more than expected in August.
Money markets on Monday pointed to a roughly 90 per cent chance of a rate hike, up from around 60 per cent a week ago, according to CME Group’s FedWatch tool.
“The U.S. dollar has strengthened modestly at the start of this week, encouraged by building expectations that the Fed will begin tightening monetary policy,” said Lee Hardman, senior currency analyst at MUFG.
Yet Hardman said the Fed may be reluctant to hike rates too aggressively in an election year, potentially limiting the dollar’s gains.
Rising bets on rate hikes around the world have pushed bond yields to multi-year or multi-decade highs in the US, Europe and Japan. So far the impact on the FX market has been relatively limited, as yields have largely moved in tandem.
Markets are all but certain the Bank of Japan will raise rates on Friday and will be looking for clues on whether more increases are coming.
Signs are emerging of a shift in market sentiment for the yen, with speculators turning to a net long position on the Japanese currency for the first time since February.
The Bank of England is expected to keep borrowing costs on hold on Thursday, but traders now expect a rate increase later this year and more in 2027 after the European Central Bank hiked last week. REUTERS
