The US Office of the Comptroller of the Currency (OCC) has confirmed banks under its jurisdiction can trade crypto on behalf of customers and outsource some crypto activities to third parties.
Acting comptroller Rodney Hood said in a May 7 letter that banks and federal savings associations can buy and sell crypto they hold in custody at customers’ direction.
The OCC added in a press release that financial institutions can also outsource bank-permissible crypto activities, including custody and execution services, to third parties in compliance with applicable law.
“Additionally, these banks may provide other custody services, including record keeping, tax or reporting services for their customers,” Hood said in a May 7 video posted to X.

“OCC banks may use a sub-custodian to provide the same services subject to appropriate third-party risk management practices, while a range of cryptocurrency and digital asset activities may be performed by banks and their third parties,” he added.
Previously, the OCC eased its stance on how banks can engage with crypto on March 7 by giving the green light for crypto-asset custody, some stablecoin activities, and participation in independent node verification networks such as distributed ledgers.
“More than 50 million Americans hold some form of cryptocurrency. This digitalization of financial services is not a trend; it is a transformation,” Hood said.
The OCC is an independent bureau within the US Department of the Treasury that regulates and supervises all national banks and also the federal branches of foreign banks.
Industry supports the OCC letters
Katherine Kirkpatrick Bos, general counsel at ZK-rollup developer StarkWare, said the letters signal a “shift in the OCC’s approach,” which now appears to favor a focus on integrating crypto within banking frameworks.
“More guidance will give further clarity [and] will allow banks to re-enter crypto [without] the fear of existential regulatory risk,” she said.
She added the OCC’s “explicit permission today allowing banks to outsource bank-permissible crypto-assets is a boon to regulated crypto native service providers.”
Chief policy officer at crypto exchange Coinbase, Faryar Shirzad, also applauded the move, saying in a May 7 post to X, Hood’s commitment to “regulatory clarity, as well as his adherence to supervisory best practices and the letter of the law,” is appreciated.
In April, the US Federal Reserve announced it was withdrawing guidance that was created to deter banks from engaging in crypto and stablecoin activities.
US President Donald Trump also signed a joint congressional resolution on April 11, overturning a Biden administration-era rule that would have required decentralized finance protocols to report transactions to the Internal Revenue Service.
Taiwanese lawmaker Ko Ju-Chun has called on the government to consider adding Bitcoin to its national reserves, suggesting it could serve as a hedge against global economic uncertainty.
Ko, a legislator at-large in Taiwan’s legislative body, the Legislative Yuan, took to X on Friday to report that he had advocated Bitcoin (BTC) investment by the Taiwanese government at the National Conference on May 9.
In his remarks, Ko cited Bitcoin’s potential to become a hedge amid global economic risks and urged Taiwan to recognize the cryptocurrency alongside gold and foreign exchange reserves to boost its financial resilience.
Ko highlighted that Taiwan is an export-driven economy that has experienced significant fluctuations in its national currency, the New Taiwan dollar, amid global inflation and intensifying geopolitical risks.
“We currently have a gold reserve of 423 metric tons, and our foreign exchange reserves amount to $577 billion, including investments in US Treasury bonds,” the lawmaker stated.
In a scenario of more intense currency volatility or potential regional conflicts, Taiwan may “very likely be unable to ensure the security and liquidity,” Ko continued, adding that Bitcoin could be a great addition to Taiwan’s reserves for several reasons.

“Bitcoin has been operating for over 15 years. It has a fixed total supply, is decentralized, and is resistant to censorship. Many countries are focusing on its hedging attributes. At the same time, in intense situations, it may not face the risk of embargo,” he said.
Instead, the legislator suggested adding a “small proportion of Bitcoin” into the diversified assets as tools for sovereign asset allocation and risk hedging, and backup capacity of Taiwan’s financial system.
“When exchange rate risk and regional uncertainty increase, it is time to introduce new tools to construct a more flexible financial strategy framework,” Ko said, adding:
“As former Dean Chen Chong said, Bitcoin is the gun of the digital era. It may also be the gold of the digital era, the silver of the digital era. Or it could be gunpowder. A wise nation will not let weapons be in others’ hands.”
German law enforcement seized 34 million euros ($38 million) in cryptocurrency from eXch, a cryptocurrency platform allegedly used to launder funds stolen after Bybit’s record-breaking $1.4 billion hack.
The seizure, announced on May 9 by Germany’s Federal Criminal Police Office (BKA) and Frankfurt’s main prosecutor’s office, involved multiple crypto assets, including Bitcoin (BTC), Ether (ETH), Litecoin (LTC) and Dash (DASH). The move marks the third-largest crypto confiscation in the BKA’s history.
The authorities also seized eXch’s German server infrastructure with over eight terabytes of data and shut down the platform, the announcement added.
eXch exchanged crypto without AML
In the statement, the BKA described eXch as a “swapping” service that allowed users to exchange various crypto assets without implementing Anti-Money Laundering (AML) measures.
The platform had operated since 2014 and reportedly facilitated about $1.9 billion in crypto transfers, some of which were believed to be of “criminal origin,” including assets laundered during the Bybit hack.

“Among other things, a portion of the $1.5 billion stolen from the Bybit crypto exchange, which was hacked on Feb. 21, 2025, is said to have been exchanged via eXch,” the authorities wrote.
Multisig, FixedFloat among laundering cases
According to a post by crypto sleuth ZachXBT, eXch was also involved in laundering millions of funds from other crypto thefts and exploits, including Multisig, FixedFloat and the $243 million Genesis creditor theft.
Those were in addition to “countless phishing drainer services over the past few years with refusal to block addresses and freeze orders,” ZachXBT said.

ZachXBT was among the first security analysts to report on eXch’s links to laundering $35 million of crypto assets stolen from Bybit soon after the hack was confirmed.
“Lazarus Group transferred 5K ETH from the Bybit Hack to a new address and began laundering funds via eXch (a centralized mixer) and bridging funds to Bitcoin via Chainflip,” ZachXBT wrote in a Telegram post on Feb. 22.
“Even though we have been able to operate despite some failed attempts to shut down our infrastructure […], we don’t see any point in operating in a hostile environment where we are the target of SIGINT [Signals Intelligence] simply because some people misinterpret our goals,” it wrote.
Addressing the seizure, senior public prosecutor Benjamin Krause stressed the importance of action against “quick and anonymous opportunities for money laundering for any amount.”
“Crypto swapping is an essential component of the underground economy, used to conceal incriminated funds from illegal activities such as hacking or trading in stolen payment card data, thus making them available to perpetrators,” he said.
