Scrutiny over cryptocurrency exchanges from U.S. regulators is growing by the day.

Coinbase Global Inc., ($COIN) is facing a probe from the Securities and Exchange Commission (SEC) following recent charges being brought against a former product manager of the company for insider trading.

The SEC's current investigation into Coinbase is meant to determine whether or not the exchange let Americans trade cryptocurrencies that should have been listed as securities, according to three sources. The SEC probe actually predates the most recent arrest of Coinbase's former product manager, as noted in a previous SEC filing.

The former Coinbase employee, Ishan Wahi, allegedly worked with his brother and one other individual to leverage insider information related to the listing of specific tokens to take advantage of market conditions.

During the time of the arrest the SEC did not accuse Coinbase of committing insider trading itself, nor did it bear any responsibility for the former employee's actions against the exchange. However, the regulator did determine that nine of the tokens leveraged for insider trading were considered securities. Coinbase confirmed that the platform lists seven of these securities on a blog written by its chief legal officer, Paul Grewal, but denies that the assets are actually a security.

"The SEC's charges put a spotlight on an important problem: the US doesn't have a clear or workable regulatory framework for digital asset securities," wrote Grewal. "And instead of crafting tailored rules in an inclusive and transparent way, the SEC is relying on these types of one-off enforcement actions to try to bring all digital assets into its jurisdiction, even those assets that are not securities."

Following the announcement of Coinbase's securities listing probe, a report from the New York Times stated that Kraken is also coming under investigation by the Treasury Department for allegedly enabling sanctioned users in Iran and other restricted regions to continue purchasing different cryptocurrencies.
