Crypto exchange Kraken is teaming up with Mastercard to let crypto holders in the UK and Europe spend their digital assets at more than 150 million merchants worldwide, Mastercard announced.

Kraken will offer physical and digital debit cards, allowing customers to use crypto and stablecoins in everyday transactions. It’s the latest development in Kraken Pay, a service that debuted earlier this year that enables cross-border payments in over 300 crypto and fiat currencies.

More than 200,000 users have already activated their “Kraktag,” a unique identifier tied to their Kraken wallet, simplifying the use of Kraken Pay’s services, according to the press release.

David Ripley, Kraken’s co-CEO, said the initiative aims to close the gap between the crypto economy and traditional spending. “Our customers want to easily pay for real-world goods and services using their crypto or stablecoins,” Ripley said.

The debit cards are expected to be available in the coming weeks.

Nouriel Roubini, the economist who predicted the 2008 global financial meltdown to earn himself the nickname Dr. Doom, warned traders against relying on the Federal Reserve for a swift resolution to the financial market instability sparked by President Donald Trump’s tariffs on international trade.

A week ago, Trump announced sweeping tariffs against many nations, including a hefty levy on Chinese imports that’s now been lifted to 104%. Financial markets cratered on concerns the move will drag the U.S. and other economies into recession.

The Nasdaq 100 has lost 12% and bitcoin (BTC), the largest cryptocurrency by market value, dropped 10%, hitting prices below $75,000 at one point. Volatility in the U.S. Treasury market exploded, with yields on longer-dated bonds surging, sending prices lower even as equity markets swooned. That has raised fears of a full-blown dollar liquidity crisis like the one observed five years ago during the COVID crash.

Speculation is rife the Federal Reserve will soon take action to ease liquidity conditions, as it did in 2020, putting a floor under asset prices. Traders have priced in at least five quarter-point interest-rate cuts from Fed Chair Jerome Powell for this year, according to the CME’s FedWatch tool. Roubini suggests that won’t happen.

«There is, of course, a game of chicken between the Trump put and the Powell put. But I would say that the strike price for the Powell put is going to be lower than the strike price for the Trump put, meaning Powell is going to wait until it’s Trump who blinks,» Roubini told Bloomberg.

In other words, Powell will likely wait for Trump to temper his rhetoric before intervening to stabilize market volatility. This approach makes sense given the current market instability is largely a result of Trump’s tariffs.

The sentiment could quickly reverse with a single-social media post from Trump announcing a possible trade deal or negotiation with China. An episode from early this week is symptomatic. On Monday, an unconfirmed report of a tariff pause triggered a sharp surge in market valuations, only for the news to later be debunked as false.

Sticky inflation, no recession

Roubini, who runs Roubini Macro Associates, expects inflation to be sticky in a new world of higher tariffs, hurting longer-dated bonds. That partly explains the swoon in the 10- and 30-year U.S. Treasury notes and the resulting surge in yields.

At the same time, he said he expects the U.S. to avoid slipping into a recession, contrary to the market zeitgeist and pricing in betting platforms, which suggests an over 50% chance of the economy facing back-to-back quarterly contractions in the growth rate.

Investment manager ARK Invest, which is known for buying the dip when markets go south, has purchased 199,401 Coinbase (COIN) shares in the past three days.

Based on closing prices, the shares would have cost a total of $31.51 million. They are now valued about $29.3 million based Tuesday’s close.

The St. Petersburg, Florida-based company aims to avoid having one particular holding account for a weighing of more than 10% of an exchange-traded fund’s (ETF) total value. When a particular stock falls, it presents a buying opportunity for ARK.

Coinbase shares have fallen over 15% in the last week as both cryptocurrency and equity markets tumbled following the steep import tariffs imposed by U.S. President Donald Trump.

BTC is around 8% lower than a week ago, while the S&P 500 and Nasdaq have both dropped more than 10%.
