The Public Company Accounting Oversight Board (PCAOB) — a watchdog that oversees audits of public companies in the United States — recently issued an advisory that warned investors about proof-of-reserves (PoR) reports issued by auditing firms.
Crypto entities may engage a service provider to issue “proof of reserve” reports. A new Investor Advisory from the PCAOB’s Office of the Investor Advocate urges investors to exercise caution with these reports. https://t.co/aAykzlc7k1 #PCAOBresources pic.twitter.com/7S6jLCC2np

The PCAOB, backed by the U.S. Securities and Exchange Commission (SEC), pointed out that investors should not “place undue reliance” on PoR reports, which are not within the board’s oversight authority. The advisory wrote:
“Importantly, investors should note that PoR engagements are not audits and, consequently, the related reports do not provide any meaningful assurance to investors or the public.”
In addition, the board also argued that PoR reports don’t provide assurances on the state of the assets after issuing the report. According to the PCAOB, PoRs don’t reflect if the assets were used, lent or became unavailable to customers after the report’s publication. The board also said that PoR reports do not assure the effectiveness of the crypto entity’s internal controls or governance.
The board noted that PoR reports are not conducted in accordance with the PCAOB auditing standards. Furthermore, the board highlighted a lack of uniformity among service providers of PoR reports.
“Proof of reserve reports are inherently limited, and customers should exercise extreme caution when relying on them to conclude that there are sufficient assets to meet customer liabilities,” the advisory added.

The warning came after many crypto exchanges jumped on the trend of providing PoR reports in an attempt to assure investors of their financial safety after the FTX debacle. On Jan. 19, crypto exchange OKX declared $7.5 billion in liquid assets in its PoR report. On Feb. 23, exchange MEXC Global released its PoR after 45 days of testing.
More recently, crypto exchange Binance added 11 tokens to its PoR report, claiming $63 billion in reserves on March 7.
