U.S. diesel prices have reached a record high, raising concerns that higher fuel costs could eventually feed into consumer inflation and reinforce expectations for further Federal Reserve rate hikes. The central bank appears to be tightening policy even as an oil supply shock remains a key source of price pressure.
The national average price for diesel climbed to $6.29 per gallon this week, its highest level on record and nearly 80% above its level at the start of the year, according to TradingView. Bitcoin was trading around $76,400, down nearly 12% year to date, while gold was little changed after retreating from its $5,600 record set earlier this year.
The jump in diesel prices has been largely linked to heightened geopolitical tensions in the Middle East, including the ongoing U.S.-Israeli conflict with Iran. Disruptions to crude oil flows have pushed up risk premiums for refined products, while limited refinery capacity and solid demand from freight and industrial users have added further upward pressure.
The combination has turned a regional supply disruption into a broader increase in energy prices. Higher diesel costs can also spread through the economy as transportation and supply-chain expenses rise, potentially lifting prices paid by consumers.
“Higher diesel prices can show up in inflation through business costs first, then potentially affect consumer prices over time depending on pass-through and demand,” JPMorgan said in a Tuesday note.
The renewed energy shock comes as central banks remain focused on inflation and continue to consider tighter monetary policy. Higher rates can make borrowing more expensive and slow demand, but they may not directly resolve inflation caused by disruptions to oil supplies related to conflicts involving Iran and Ukraine.
The Federal Reserve raised its benchmark interest rate by 25 basis points on Thursday, bringing the target range to 3.75%-4%. Some observers have questioned the effectiveness of using higher rates to address inflation stemming from an oil supply shock.
Goldman Sachs and Morgan Stanley expect the Fed to raise rates by another 25 basis points in October. Other central banks are also moving toward tighter policy, with the European Central Bank recently increasing rates and the Bank of Japan expected to do so on Friday.
Record diesel prices could create additional pressure for Bitcoin, gold and technology stocks. Bitcoin, like gold, is often viewed as a store of value and a hedge against sovereign risks. However, the cryptocurrency has historically faced pressure when borrowing costs rise, as demonstrated during the Federal Reserve’s tightening cycle in 2022.
