Energy shock and inflation risks revive “higher-for-longer” outlook
On March 18, the U.S. Federal Reserve and the Bank of Canada both held interest rates steady. Across the same week, major European central banks also leaned toward policy stability, signalling that global monetary policy has entered a phase of synchronised pause. The escalation of conflict involving Iran has unsettled oil markets, inflation expectations and growth prospects at once.
This is more than a routine hold. Rising geopolitical risk has tightened the policy trade-off, forcing central banks to weigh renewed inflation pressure against signs of slowing growth. Markets, in turn, are shifting their focus from the direction of rates to the duration of current levels.
The Federal Reserve kept its benchmark rate at 3.50–3.75% at its March 18 Federal Open Market Committee meeting. The 11–1 vote, with one dissent in favour of a rate cut, underscored growing internal uncertainty about the path ahead. Inflation has not fully subsided, and the addition of geopolitical risk has complicated the timing of any policy shift.
The Bank of Canada made a similar decision the same day, holding its policy rate at 2.25%. While higher oil prices can support Canada’s export revenues, the economy remains highly sensitive to borrowing costs due to elevated household debt. For policymakers, holding steady appears less risky than moving prematurely in either direction.
Europe is showing a comparable pattern. The European Central Bank, Bank of England and Swiss National Bank have all tilted towards maintaining current policy settings, as war-driven energy shocks threaten to disrupt disinflation روند and supply chains. The result is a convergence of policy stance despite differing domestic conditions.

What binds these decisions is not uniform economic strength, but shared exposure to the same external shock. War, energy and inflation have become global variables, pushing central banks towards similar conclusions. March may come to be seen as the moment when monetary policy paused in unison.
Crucially, this pause reflects constraint rather than confidence. Cutting rates risks reigniting inflation amid rising oil prices, while tightening could deepen an already fragile growth outlook. With the shock rooted in supply-side disruptions, monetary policy has limited tools to respond effectively.
If the Iran conflict persists or escalates, markets may have to adjust to a renewed “higher-for-longer” regime. Sustained energy price pressure combined with weaker growth would leave central banks reluctant to ease. In this environment, how long rates stay elevated matters more than where they peak.
The synchronised hold of March is therefore less an end to the rate cycle than the start of a new phase. The key question is no longer when cuts will begin, but how long central banks can afford to wait. As geopolitics reasserts itself, time—not direction—has become the defining variable of monetary policy.
