Weekly FX Roundup: From Energy Shock to Yield Stress

Friday is upon us, and while today’s session is likely to be relatively quiet, this week’s price action has been anything but. 

We are releasing this week’s roundup following a sharp shift in currency markets. Sterling has reversed lower against the dollar, while GBP/EUR has once again failed to break sustainably above the 1.16 level. These moves are not isolated. They reflect a deeper change in how markets are interpreting risk. 

At the start of the week, the focus was clear. Markets were reacting to the escalation in the Middle East and the potential for disruption to global energy supply. 

By the end of the week, that narrative had evolved. 

This is no longer just a geopolitical story. It is a macroeconomic one. 

Currency markets are no longer reacting to headlines alone. They are reacting to the economic consequences of an energy shock.  

From Headline Shock to Macro Repricing 

The initial phase of the conflict was driven by volatility. 

Oil prices surged, risk sentiment deteriorated, and safe haven currencies strengthened. The moves were sharp but largely reactive. 

The second phase has been more important. 

Markets are now reassessing how sustained disruption to energy flows, particularly through the Strait of Hormuz, will impact inflation, growth and monetary policy across the G10. 

With approximately 20% of global oil and gas passing through this route, the risk is not just higher prices, but prolonged disruption. 

That shift has forced a repricing of interest rate expectations globally. 

The Dollar: Dominant and Reinforced 

The US dollar has remained the central force in FX markets this week. 

It continues to benefit from safe haven demand as geopolitical risks persist, but more importantly, it is supported by structural factors. The United States is now a major energy producer, meaning higher oil prices are less damaging to its economic outlook than for many of its peers. 

Even as markets have reassessed the Federal Reserve’s path, the dollar has remained firm. In the current environment, liquidity and stability are being prioritised over yield. 

Unless there is a clear de-escalation in the Middle East, the conditions supporting the dollar remain firmly in place.  

The Euro: Structural Vulnerability 

The euro remains one of the clearest casualties of the current environment. 

The Eurozone’s reliance on imported energy leaves it particularly exposed when oil and gas prices rise. This creates a difficult balance for the European Central Bank, where inflation pressures increase at the same time as growth risks intensify. 

Even as markets begin to consider tighter policy further out, the currency has struggled to find support. 

Sterling: From Support to Strain 

Sterling has been one of the more interesting stories this week. 

Earlier in the week, the pound was supported by rising UK government bond yields, as markets rapidly repriced expectations around Bank of England policy. What had previously been a rate-cut narrative shifted toward a more hawkish outlook as inflation risks re-emerged. 

However, by the end of the week, that support began to fade. 

Sterling reversed lower against the dollar, and GBP/EUR once again failed to break above 1.16 despite widening yield differentials that would typically support further gains. 

The shift in sterling has been reinforced by developments in UK bond markets, where government borrowing costs have surged to levels last seen during the 2008 financial crisis. Crucially, this is not being driven by stronger growth expectations, but by rising inflation risk and mounting fiscal pressure. 

As yields rise for the wrong reasons, the signal to currency markets changes. 

Instead of attracting capital, higher yields begin to reflect risk. 

That transition appears to be underway.  

Energy Exporters: Supportive but Not Absolute 

Energy-linked currencies such as the Canadian dollar and Norwegian krone have generally benefited from higher oil prices, as stronger energy markets tend to improve trade balances and economic outlooks. 

However, this week has also shown that the relationship is not absolute. 

The Canadian dollar, in particular, has underperformed at times, reflecting the growing importance of interest rate differentials over commodity exposure. As other central banks shift toward a more hawkish stance, currencies tied more directly to rate expectations have at times outpaced traditional energy beneficiaries. 

This highlights an important shift. 

Markets are no longer trading a single theme. They are balancing energy exposure against monetary policy divergence.  

Safe Havens and the Rest of G10 

The Swiss franc has behaved as expected, attracting defensive flows as geopolitical risks remain elevated. 

The Japanese yen presents a more conflicted picture. While it retains safe haven characteristics, Japan’s heavy reliance on imported energy creates a structural headwind in the current environment. 

Elsewhere, the Australian dollar has been supported by commodities and rising domestic yields, although it remains sensitive to broader shifts in global risk sentiment. 

The New Zealand dollar continues to sit in the middle, balancing inflation support against growth vulnerability.  

 

Markets Are Volatile, Not Yet in Panic 

Markets this week have been anything but calm. 

Daily moves across FX have regularly pushed towards 1%, with sharp reversals in pairs such as GBP/USD and EUR/USD reflecting fast-changing sentiment around energy prices, central bank expectations and geopolitical risk. 

This is not a stable environment. It is a volatile one. 

However, despite this volatility, markets have not yet transitioned into full panic mode. 

Equity indices remain relatively close to recent highs, credit markets have not shown signs of severe stress, and price action, while aggressive, remains orderly rather than disorderly. 

In other words, this is a market actively repricing risk, not one experiencing forced liquidation. 

That distinction matters. 

Because while conditions are currently volatile, they remain fragile. If energy disruption intensifies or geopolitical escalation accelerates, the transition from controlled volatility to broader market stress could happen quickly. 

Bottom Line 

Markets began the week repricing the immediate consequences of the conflict. 

They are ending it questioning the resilience of the global energy system and the stability of the economies most exposed to it. 

The late-week shift in sterling is a clear example of this transition. Earlier support from rising yields has faded as markets begin to question the sustainability behind those moves, particularly in an environment of elevated inflation risk and rising borrowing costs. 

Until there is a credible path toward reopening the Strait of Hormuz and stabilising global energy flows, currency markets will remain divided along clear structural lines. 

Energy exporters versus energy importers.

In this environment, the dollar continues to benefit from both safety and structural advantage, while currencies such as the euro and, increasingly, sterling reflect the pressures of energy dependence and fiscal sensitivity. 

For now, the message from FX markets is clear. 

This is no longer a market reacting to geopolitical headlines. 

It is a market repricing the global energy order, and the currencies tied to it.
