- Sterling's plunge comes after last week's announcement by the new U.K. government that it would implement tax cuts and investment incentives to boost growth.
- Critics say those economic measures will disproportionately benefit the wealthy and could see the U.K. take on high levels of debt at a time of rising interest rates.
The British pound plunged to a record low on Monday morning in Asia, following last week's announcement by the new U.K. government that it would implement tax cuts and investment incentives to boost growth.
Sterling briefly fell 4% to an all-time low of $1.0382 on Monday, continuing its sluggish trade in recent months as the U.S. dollar strengthens. The U.K. currency last traded down about 1.5% $1.069 against the greenback.
"[It] doesn't seem like the U.K. government is throwing the market a bone here in terms of having a much more tempered fiscal trajectory, and so I think at this point right now, the path of least resistance is going to remain lower," Mazen Issa, senior forex strategist at TD Securities, told CNBC before the pound hit a new low.
"Below $1.05, you really look at parity," he told CNBC's "Squawk Box Asia."
"We've seen the euro dip below parity — I don't see a reason why sterling can't either," Issa added.
It's a "major challenge" for the Bank of England to fight inflation while the government tries to stimulate the economy, said Nicholas Ferres, chief investment officer at Vantage Point Asset Management.
"The Bank of England may even do an emergency policy meeting this week and hike rates, that wouldn't surprise me if that happened," he said.
The lack of commitment to fiscal discipline in the U.K., along with the strong dollar, led to the pound weakening sharply, said Saktiandi Supaat, FX strategist at Maybank.
"I think that [the] collapse in the sterling actually led to further risk aversion, generally risk-off sort of sentiment, intensifying further down," he said.
Billed as a "mini-budget" by U.K. Finance Minister Kwasi Kwarteng, Friday's fiscal announcement saw a volume of tax cuts not seen in Britain since 1972. Market players immediately predicted Britain would have to scale up its bond issuance and significantly increase its debt load to pay for the reductions. On Sunday, Kwarteng also talked up the possibility of more tax cuts in the coming months.
Jim O'Neill, former Goldman Sachs Asset Management chairman and a former U.K. Treasury minister, said the pound's fall shouldn't be misinterpreted as dollar strength.
"It is a consequence of an extremely risky budget by the new chancellor and a rather timid Bank of England that, so far, has only raised rates reluctantly despite all the clear pressures," he told CNBC on Monday.
In the Asia-Pacific region, Japan, South Korea and China's currencies weakened against the greenback, while the Australian dollar was about flat.
The Japanese yen traded up .9% at 144 levels against the dollar, weaker compared with after authorities intervened in the currency market last week.
South Korea's won was near 2009 levels at 1,428.84 per dollar.
The U.S. dollar index has been rising strongly this year as the Federal Reserve raises interest rates aggressively. In particular, interest rate differentials between the U.S. and Japan have widened significantly as the Bank of Japan sticks to its ultra-low rates.
