The Great Hawkish Turn: Central Banks Tighten in Unison as War Lifts Inflation

Executive Summary

LONDON — The world's major central banks have turned hawkish in unison. In the space of three days, Australia's central bank lifted its cash rate to an 18-year high, the Bank of England raised interest rates for the first time in more than three years, and traders kept a December increase by the United States Federal Reserve priced at roughly two-in-three odds. The trigger in each case was the same: a Middle East conflict now in its ninth month, pushing energy prices higher and forcing inflation forecasts up across the developed world.

The shift is striking because it reverses the direction of travel set only months ago. Bank of America counts 55 rate increases delivered or expected from major central banks this year, against just 11 expected in January, with 41 of them in the past six months. The era of cheap money, briefly interrupted by the pandemic-era inflation fight, is giving way to a longer, harder squeeze — and this study measures how far it has already gone.

Methodology

This study rests on the official decisions and forecasts published by the central banks themselves — the Reserve Bank of Australia's November 3 statement and Statement on Monetary Policy, the Bank of England's November 5 Monetary Policy Report, and the Federal Reserve's October 28 decision and press conference — cross-checked against reporting by Reuters, the Financial Times' wire services and market data from CME FedWatch and Bank of America research.

Every figure is labelled as an outcome, a forecast or a market-implied probability, and forecasts are never presented as facts. Where sources disagree on a market price or an odds reading, the study uses the most recent reading available at the time of writing and says so. The method follows our earlier study of the November artificial-intelligence sell-off and the central-bank squeeze, which separated counted data from projections before drawing conclusions.

Empirical Findings

Australia moved first. On November 3 the Reserve Bank lifted its cash rate by 25 basis points to 4.85 percent, its fifth increase of 2026 and the highest level since late 2008. The nine-member board split six to three, with the minority preferring to hold. Underlying inflation had reached a two-year high of 3.7 percent in the third quarter, while headline consumer prices rose 4.3 percent in the year to September, up from 4.0 percent in August.

The bank's new forecasts explain the urgency. Headline inflation is now expected to peak at 4.5 percent in the December quarter, against 3.6 percent forecast in August, and stay above 3 percent until the end of 2027. The bank expects inflation to reach the top of its 2 to 3 percent target band only in late 2027, and the 2.5 percent midpoint in mid-2028. Growth is forecast at 1.6 percent through mid-2027, slowing to 1.3 percent by year-end, with unemployment rising from 4.7 percent to 5.1 percent by end-2028.

Britain followed two days later. On November 5 the Bank of England raised Bank Rate by 25 basis points to 4 percent from 3.75 percent, an eight-to-one vote, with Catherine Mann dissenting in favour of a half-point rise to 4.25 percent. It was the first increase since August 2023. Consumer price inflation had reached 3.5 percent in September, the highest in eleven months, and the bank now expects it to reach around 5 percent by the middle of next year — more than double its 2 percent target.

The Bank's central projection puts the inflation peak at 4.8 percent in the second quarter of 2027, with no return to target until the third quarter of 2028. In an adverse scenario, with oil near 130 dollars a barrel against about 100 now, inflation would peak at 6.2 percent in the third quarter of 2027 and stay above target throughout the forecast period. Governor Andrew Bailey said January utility bills alone add around 0.4 percentage points to headline inflation.

The United States has not yet moved, but the direction is clear. On October 28 the Federal Reserve held its policy rate at 3.75 to 4.00 percent in a ten-to-two vote, with Governor Lisa Cook and Cleveland Fed President Beth Hammack dissenting for an immediate increase. Chair Kevin Warsh said inflation had stayed above target for about six years and gave no guidance on the December 8 to 9 meeting. Futures priced a December hike at roughly two in three by November 6, down from above 80 percent after the midterms and the equity rout.

The turn extends well beyond the three largest English-speaking economies. Bank of America puts a European Central Bank increase on December 17 at 76 percent likely and a Bank of Japan increase on December 18 at 68 percent. China's central bank has already tightened through the back door, raising its foreign-exchange reserve requirement ratio from 4 to 6 percent from November 15, worth roughly 24 billion dollars of withdrawn liquidity. In the Philippines, inflation accelerated to 7.8 percent in October from 7.2 percent in September after a larger-than-expected rate rise.

Energy is the thread running through every decision. Brent crude settled at 115.32 dollars on October 28, fell about 9 percent to 94.50 dollars on November 4 as diplomacy hopes rose, then snapped back to 98.29 dollars on November 5 after fresh tanker incidents in the Gulf. The Strait of Hormuz carries about a fifth of the world's oil and liquefied natural gas, so every incident reprices both oil and inflation expectations within hours — a link tracked in our study of the Hormuz energy shock.

Markets have felt the squeeze. The Nasdaq fell 5.52 percent on November 5, its worst day since April 2025, as about 2.5 trillion dollars of value vanished in the artificial-intelligence rout. The S&P 500 closed the week at 6,720.32 and the Nasdaq at 23,053.99, while the Dow retreated to 46,912.30 after an all-time high midweek. The dollar index climbed above 100 on November 4, its highest in three months, the euro fell below 1.15 dollars, and the ten-year Treasury yield hovered around 4.1 percent.

Gold tells the other side of the story. Bullion closed at 4,088 dollars an ounce on November 5 after touching 4,146 dollars, its highest in two weeks, as fading December hike odds and the equity rout pulled investors toward safety. The metal remains far below its January record of 5,589.38 dollars, but the rebound underlines how quickly sentiment swings when the rate outlook shifts — a divide examined in our study of record central-bank gold buying.

Outlook

December now carries four decisions in ten days: the Reserve Bank of Australia on December 8, the Federal Reserve on December 8 to 9, the Bank of England on December 17 and the European Central Bank and Bank of Japan in the same week. Bank of America strategists argue that weaker-than-expected United States consumer price and payroll data could make those December increases the final hikes of the cycle, setting up a year-end rally. The October employment report lands on November 7 and consumer prices on November 10.

Three risks will decide whether the hawkish turn holds. First, whether the Middle East conflict keeps energy prices near 100 dollars a barrel or pushes them toward the 130-dollar adverse case. Second, whether the United States government shutdown, now in its 35th day and tied for the longest in history, further delays the economic data the Federal Reserve needs. Third, whether growth — already forecast to slow in Australia and Britain — can absorb higher borrowing costs without tipping into recession.

For households the message is already concrete: Australian borrowers face a fifth rate rise this year, with the big four banks passing the full increase to variable home loans from November 13, while British mortgage holders face the first rise in three years. The central banks have chosen to fight inflation first and worry about growth second. News Plus Globe's business and finance desk will track the December decisions and the data that shapes them.
