Sterling slumped to a record low on Monday, prompting speculation of an emergency response from the Bank of England, as confidence evaporated in Britain’s plan to borrow its way out of trouble, with spooked investors piling into U.S. dollars.
The carnage was not confined to currencies, as concerns that high interest rates could hurt growth also knocked Asian shares to a two-year low, with demand-sensitive stocks such as Australia’s miners and carmakers in Japan and Korea hit hard.
S&P 500 futures fell 0.8% and European futures fell 0.7%. Two-year Treasury yields broke above 4.3% to a new 15-year high. The euro hit a 20-year low.
“The movements over the last couple of trading days are quite fierce,” said Paul Mackel, global head of FX research at HSBC in Hong Kong. “It’s a strong reminder about how suddenly the drivers for exchange rates can change.”
The pound plunged nearly 5% at one point to break beneath 1985 lows and hit $1.0327. Moves were exacerbated by thinner liquidity in the Asia session, but even after stumbling back to $1.05, the currency is still down some 7% in just two sessions. Options pricing implies a wild ride ahead.
“The market is now treating the UK as if it’s an emerging market,” said Rabobank strategist Michael Every in Singapore.
“And they’re not wrong in terms of the policy response and the naivety of thinking that boosting demand rather than supply is how you deal with a supply side shock,” he said.
“If this carries across into European trading you’re going to get at a minimum a public statement from the BOE threatening (action) and…a strong possibility that they have to make an inter-meeting hike, and a chunky one at that.”
Britain’s announcement of unfunded tax cuts already set off the heaviest selling of gilts in three decades on Friday and has pushed the pound to a near two-year low of 92.29 pence per euro .
