Key Highlights

  • Bessent compared the law to the National Currency Act of 1863, signed by Abraham Lincoln, and called it "a watershed moment in American finance" on the day the rules were published.
  • Bitcoin rose above USD 84,000 and the iShares Bitcoin Trust ETF gained about 3%, while Circle and Coinbase shares rose about 6% and 5% respectively in the same session.
  • The gains faded on Thursday, October 22, 2026, when bitcoin slipped below USD 82,000 during an Asian equity sell-off and leveraged bullish bets were liquidated.

A Civil War Parallel for Stablecoins

iShares Ethereum Trust ETF (NASDAQ:ETHA), a fund that holds ether, followed a broad crypto rally on Wednesday, October 21, 2026. The Office of the Comptroller of the Currency (OCC) finalised its rules for stablecoin issuers under the GENIUS Act that day. Treasury Secretary Scott Bessent called the law "a watershed moment in American finance." He compared it with the National Currency Act of 1863, signed by Abraham Lincoln during the Civil War. Bitcoin, ether, XRP and dogecoin all rose, with bitcoin climbing above USD 84,000. The iShares Bitcoin Trust ETF (NASDAQ:IBIT) gained about 3%. Circle Internet Group (NYSE:CRCL) rose about 6% and Coinbase about 5%. The rules take effect in January 2027.

Why the 1863 Comparison Points to Ether

For iShares Ethereum Trust ETF (NASDAQ:ETHA), the comparison matters through usage. The 1863 law created the OCC and a system of national banknotes backed by federal government bonds, replacing a patchwork of state bank currencies. The GENIUS Act echoes that design: dollar stablecoins must be backed by safe assets such as Treasury bills, under federal supervision that again involves the OCC. A large share of dollar stablecoins circulates on the Ethereum network, where every transfer pays a fee in ether. Clear rules could draw banks, payment firms and corporate treasurers into stablecoins, raising activity and demand for block space. ETHA tracks the ether price, so policy news reaches the fund only through the market price of the token.

Risks and What to Watch

The first risk for iShares Ethereum Trust ETF (NASDAQ:ETHA) is that policy optimism fades faster than usage grows, as Thursday's reversal showed. Bitcoin fell below USD 82,000 on Thursday, October 22, 2026, and about USD 250 million to USD 267 million of positions were liquidated, depending on the measure. The second risk is competition, since stablecoins also run on other blockchains, so higher volumes need not accrue to Ethereum. The third is macro: the Fed raised rates on Wednesday, September 16, 2026, and Asian markets fell 2% to 3.5% on AI-spending doubts. Investors should watch the Fed decision on Wednesday, October 28, 2026, the midterm elections on Tuesday, November 3, 2026 and the January 2027 effective date.

Where Things Stand

The answer is that the 1863 comparison frames stablecoins as federally backed digital dollars, and ETHA benefits only if more of those dollars move across Ethereum. Wednesday's rally priced in that hope, but Thursday's liquidations showed how quickly leverage can reverse the move. The connection between regulation and ether demand is indirect and not proven. The next catalysts are the Fed on October 28, the midterms on November 3 and the January 2027 effective date. Crypto prices are volatile, and this is not investment advice.
