The dollar rebounded Tuesday after hitting its lowest level since 2022, while the British pound dropped 0.5% to $1.3086 on mounting fiscal concerns ahead of the UK's November 26 budget.
Sterling fell to €1.13 against the euro—its weakest since April 2023—as UK 30-year gilt yields climbed to 5.21%, the highest in 26 years. Chancellor Rachel Reeves faces pressure to balance spending commitments with market stability.
"GBP remains under pressure from fiscal instability concerns," said Simon Phillips at No1 Currency. Mizuho Bank's Jordan Rochester warned the pound could break below $1.30 if budget measures disappoint markets.
Global currency volatility is rising as traders navigate dual uncertainties: the Fed chair replacement scheduled for June 2026 and shifting geopolitical risks. Iran-US nuclear talks pushed WTI crude up 1.5% to $61 per barrel Tuesday, affecting commodity-linked currencies worldwide.
The UK gilt market showed unexpected strength despite fiscal concerns. A recent auction drew £69 billion in bids for £4.25 billion of inflation-linked bonds, exceeding March's £67.5 billion record. About 25% of UK gilts are inflation-linked, compared to 10% in the US and France, making sterling more sensitive to inflation shifts.
"There's no sign bond markets are rattled," said Julian Jessop at the Institute of Economic Affairs. Mike Riddell at Fidelity noted gilts have been "the top performer globally over the last few days and months."
European equity markets rallied Tuesday, with London's FTSE 100 hitting a record 9,911 and the pan-European Stoxx 600 reaching 583.4 points. Safe-haven currencies including the Swiss franc and Japanese yen could gain if equities reverse.
Currency traders are positioning for sustained volatility through mid-2026 as major economies navigate monetary policy transitions alongside fiscal pressures. The dollar's trajectory depends on incoming Fed leadership signals and geopolitical risk premium adjustments across global markets.
