- The euro fell to a two-decade low of 0.9903 against the U.S. dollar.
- Strategists are "definitely biased towards further euro depreciation," says a head strategist at Citi Bank.
"Our outlook and our trades and our position on the strategist side are definitely biased towards further euro depreciation from where we are now," Luis Costa, head of CEEMEA strategy at Citibank, told CNBC's "Squawk Box Europe" on Tuesday.

"This is the primary point of euro vulnerability now," Costa said.
Wholesale gas prices in Europe rose sharply on Monday after Russia announced unscheduled maintenance on its main pipeline to Germany, Nord Stream 1, while heat waves have put additional strain on energy supplies.
For the full picture, you also have to look beyond Europe and the United States, says Costa.
"Let's not forget there is an additional layer of complexity here from the China slowdown which obviously hits Europe with a much higher magnitude when compared to the impact in the States," he said.
China missed GDP expectations with growth of just 0.4% in the second quarter. The world second-largest economy has struggled with the aftermath of the country's worst Covid-19 outbreak since the start of 2020.
Until May, markets were "considering hawkish flight paths" for the European Central Bank and the Bank of England, according to Costa, but those plans have "imploded" in recent months.
"Talking about ECB liftoff… It's absolutely glaring that ECB room to lift rates will be minimal," he said.
Global finance institution ING's Roelof-Jan Van den Akker made similar predictions on CNBC's "Squawk Box Europe" last week, suggesting a widening in the interest rate differential between the U.S. dollar and the euro, as well as a further weakening of the single currency.
"[The dollar] broke below the 103.60 support level. That's a very crucial horizontal support … And I suggest that there's further downside potential to go. Longer-term target of between $0.80 to $0.75 in the coming months," Van den Akker said.
"It confirms there is dollar strength as well as euro weakness," he told CNBC.
The predictions echo concerns that inflation will continue to rise and that a recession in Europe is now unavoidable.
The dollar's strength may not last though, according to Societe Generale Macro Strategist Kit Juckes.
"Maybe, all in all, the dollar rally has run about as far as it can on the current news," he wrote in an email Tuesday morning.
"That's not to say Europe's energy woes, China's economic weakness and policy easing, and US jobs/inflation data can't send it further, but when I read that buying the dollar is 'the easiest trade in FX' the hairs on the back of my neck warn me to be careful," Juckes wrote.
And Europe should be able to recover from those "woes," according to the strategist.
"I still can't see how it can rally much on anything other than short covering, but if risk markets don't interfere, the euro can find a base here," he wrote.
