Rising energy prices, higher bond yields, and shifting interest-rate expectations are increasing the potential for sharper currency movements in October. When managing cross border payments, pricing, or cash flow across currencies, understanding the forces behind this volatility is becoming increasingly important.

Why the US dollar strengthened in September 2026
The US dollar rallied to a two-month high after the Federal Reserve raised interest rates in September. The unanimous decision helped reinforce confidence in the central bank’s commitment to controlling inflation, while signaling that further tightening remains possible.
Although higher borrowing costs would ordinarily weigh on risk appetite, global equities have remained resilient. Strong corporate earnings, continued investment in AI and digital infrastructure, and sustained consumer spending have helped markets absorb the rise in yields.
Thee key FX trends for October 2026
Three themes could play an important role in currency markets this month.
1. Will the Fed’s action rebuild market confidence?
The Federal Reserve’s September rate hike strengthened perceptions that policymakers remain focused on containing inflation. The unanimous decision was particularly important following the leadership transition to Kevin Warsh, which had prompted questions about the direction of monetary policy.
With another increase now viewed as a realistic possibility, expectations for higher US rates continue to support the dollar heading into October.
2. Diplomatic momentum remains limited
High-level discussions between US administration, Gulf leaders, and Chinese President Xi at the end of September brought renewed attention to efforts to ease tensions in the Middle East, but markets have yet to see evidence of a decisive breakthrough.
Reports of a possible phased de-escalation between the US and Iran offer a potential path forward, although confidence remains subdued after months of limited progress. Any shift in the conflict could influence energy prices, inflation expectations, and, in turn, major currency movements.
3. The UK’s fiscal message faces market scrutiny
The UK government’s October 28 Budget will offer investors their first meaningful opportunity to assess how Andy Burnham’s administration plans to combine economic ambition with fiscal restraint. With the energy crisis complicating the policy backdrop, the final measures may be more cautious than previously expected.
A restrained budget could leave markets with fewer surprises to absorb, potentially limiting near-term pressure on UK assets.
Why rising bond yields matter for FX markets
September’s global bond sell-off reinforced expectations that interest rates could remain elevated for longer. Yields rose across the US, Europe, and Japan, led by US Treasuries. The US 10-year yield climbed above 5% for the first time since 2007, while the 30-year yield reached its highest level in 22 years.
Despite the rise in borrowing costs, equity markets remained relatively resilient. Strong corporate earnings, ongoing investment in AI and digital infrastructure, and continued consumer spending helped offset some of the pressure from higher yields.
Currency markets felt the impact more directly. US yields rose faster than those of many major peers, widening interest-rate differentials and strengthening the appeal of the dollar. Resilient economic growth, higher oil prices, renewed inflation concerns, and the Federal Reserve’s hawkish stance all contributed to the move.
The next phase will depend partly on how other central banks respond. If inflation and growth conditions continue to vary across economies, policy paths could diverge further, potentially producing more sustained currency moves and greater volatility for businesses managing international payments and FX exposure.
Can the euro recover against the US dollar?
EUR/USD came under renewed pressure in September as rising oil prices and a more hawkish Federal Reserve strengthened demand for the dollar. Disruptions affecting alternative routes to the Strait of Hormuz added to energy concerns, while limited diplomatic progress kept geopolitical risks elevated.
The Fed’s unanimous 25-basis-point rate hike also helped restore confidence in its commitment to controlling inflation. EUR/USD fell by around 2%, moving below 1.14 and briefly reaching two-month lows. Although the European Central Bank raised its deposit rate by 25 basis points to 2.50%, the decision provided limited support for the euro against a broadly stronger dollar.
Looking ahead, EUR/USD is expected to remain near 1.14 while markets seek greater clarity on the Fed’s next move. A sustained decline in oil prices or meaningful geopolitical de-escalation could ease inflation concerns, reduce expectations of another US rate hike, and create room for a modest euro recovery.
However, stronger-than-expected US economic or labor market data could keep the dollar supported. If energy prices remain elevated and the prospect of further Fed tightening persists, EUR/USD could face additional pressure, with a move below June’s low of 1.1325 becoming possible.
