Bitcoin Rises, Coinbase and Strategy Stocks Also Soar After US Treasury Move

Bitcoin strengthened again and Coinbase stock surged after the market received two positive catalysts from the United States. The US Treasury's move to expand its bond buyback program helped ease pressure in the Treasury market, while government support for crypto regulation added positive sentiment for US crypto stocks.

This move lifted a number of stocks closely tied to the digital asset industry. Strategy (MSTR), Coinbase (COIN), Circle (CRCL), and Robinhood (HOOD) were among those that rallied alongside Bitcoin's rise in trading on August 19, 2026.

Key Takeaways

• The US Treasury plans to increase the size of bond buyback operations to at least US$4 billion.
• Bitcoin strengthened above US$68,000, while Coinbase, Strategy, Circle, and Robinhood stocks also rose sharply.
• President Donald Trump's support for the CLARITY Act added a regulatory catalyst for the US crypto sector.

US Treasury Expands Bond Buyback

One of the main triggers for the rally came from the US Treasury's policy on the government bond market. The Treasury plans to expand its buyback operations, mainly to help improve liquidity in outstanding debt securities.

In its third-quarter 2026 plan, the Treasury said it would buy back up to US$38 billion in outstanding bonds for liquidity support purposes. The program covers several maturity groups, including long-term debt.

The Treasury also estimated net borrowing needs from marketable debt to private investors at US$739 billion for the July–September 2026 period. That figure is US$68 billion higher than the May estimate.

For the market, this buyback is important because it can help improve the functioning and liquidity of the Treasury market. When pressure on bonds and yields eases, investor sentiment toward risk assets like technology stocks and crypto may improve.

However, the Treasury buyback is not the same as the Federal Reserve's quantitative easing (QE) program. This buyback is part of debt management and Treasury market liquidity, so it would not be accurate to directly consider it as money printing.

Bitcoin Rises and Coinbase Stock Also Strengthens

The improvement in macro sentiment was immediately felt in the crypto market. Bitcoin again broke above the US$68,000 level on August 19 and recorded a gain of about 6% in that trading session.

Bitcoin's rise then spread to public companies with exposure to the digital asset industry.

Coinbase was one of the stocks that saw big gains. COIN stock rose more than 11% to around US$162.61. Strategy also strengthened more than 12% and traded around US$103.81.

This correlation makes sense because both companies have strong ties to the crypto market. Coinbase earns revenue from trading activities and various digital asset services, while Strategy is known to hold a large amount of Bitcoin as part of its corporate treasury strategy.

The movement of these stocks shows how US stock investors use public companies as one way to gain exposure to the crypto market.

MSTR Bitcoin Is One of the Drivers of US Crypto Stocks

Strategy has a different character from Coinbase. The company makes Bitcoin a key part of its treasury strategy, so changes in BTC price can have a significant impact on investor perception of MSTR stock.

When Bitcoin experiences a sharp rise, the value of digital assets held by Strategy also gets a boost. This can improve sentiment toward MSTR, although the stock price is still influenced by other factors such as capital structure, stock issuance, preferred stock instruments, and the company's financing strategy.

In early August, CoinDesk reported that Strategy held approximately 842,138 BTC after selling 1,638 BTC worth about US$105 million during the period July 27 to August 2. That sale was used for purposes such as preferred stock dividends and STRC buybacks.

This means that the MSTR-Bitcoin relationship is indeed strong, but Strategy's stock movement cannot be explained solely by BTC price.

Circle Stock and Robinhood Stock Also Boosted

Circle (CRCL) and Robinhood (HOOD) also joined the group of stocks benefiting from improving sentiment toward digital assets.

Circle has a different position because its main business is related to the USDC stablecoin. The growth in stablecoin usage and regulatory certainty can be important factors for the company's business prospects.

Meanwhile, Robinhood has a retail trading business that includes crypto assets. When investor activity in Bitcoin and digital assets increases, companies like Robinhood could benefit from increased trading activity.

The movement of these two stocks also shows that investors are not only looking at Bitcoin as a single asset. They are starting to pay attention to public companies that provide infrastructure, trading services, and products related to the digital asset economy.

Previously, TheStreet also noted a similar pattern in July when Bitcoin again broke above US$66,000. At that time, Circle rose more than 8%, Robinhood nearly 9%, while Strategy strengthened nearly 5%.

Trump's Support for CLARITY Act Adds Positive Sentiment

Another catalyst came from Washington. President Donald Trump met with a number of crypto industry executives on August 19, 2026, and urged Congress to pass the CLARITY Act, which is seen as providing legal certainty for the digital asset industry.

The meeting was attended by several industry figures, including leaders of Coinbase and Robinhood, as well as US regulatory officials.

The CLARITY Act is important because the US crypto industry needs clearer boundaries regarding digital asset classification and the authority of regulators such as the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC).

However, the legislative process still faces hurdles. Reuters reported that the bill remains stalled in the Senate, while debates over rules and potential political conflicts of interest are also a concern.

Therefore, Trump's support acts as a sentiment catalyst, but it cannot yet be considered a guarantee that the CLARITY Act will become law soon.

Why Can Treasury Moves Impact Bitcoin?

The relationship between the Treasury and Bitcoin is indeed indirect. The mechanism is more related to liquidity conditions and investor risk appetite.

When pressure on the Treasury market eases, bond yields may also come under downward pressure. This condition could make risk assets look more attractive to some investors because safe-haven yields become relatively less competitive.

Bitcoin is among the assets that often attract attention when investors increase their exposure to risk assets. Stocks like COIN and MSTR may even move more aggressively because both have strong business or financial ties to the crypto market.

The chain of movement can be described simply:

Treasury buyback increases → bond market liquidity improves → yield pressure eases → risk appetite increases → Bitcoin strengthens → related crypto stocks are boosted.

This relationship remains market-driven and not a definitive cause-and-effect. Bitcoin and crypto stock prices are also influenced by interest rates, ETF flows, economic conditions, regulation, stock valuations, and investor positioning.

Crypto Rally Still Faces Several Risks

The rise in Bitcoin and crypto stocks on August 19 gave positive signals, but it is not enough to conclude that the market has entered a new bullish phase.

The market is still waiting for the Federal Reserve's policy direction, especially ahead of the Jackson Hole Economic Symposium. Treasury yield movements remain an important factor because changes in bond yields can affect the valuation of risk assets.

On the regulatory side, the CLARITY Act is also not yet finalized. Political support for the crypto industry can indeed improve sentiment, but investors still need to wait for actual legislative progress.

For stocks like MSTR, risks also come from Bitcoin's volatility and the company's financing structure. Meanwhile, COIN, CRCL, and HOOD each have their own business risks that are not entirely dependent on BTC price.

The US Treasury's plan to strengthen its buyback program helped improve bond market conditions, while support for the CLARITY Act gave hope for crypto regulatory clarity. 

The rally showed the increasingly close relationship between US financial market conditions and the stocks of companies with exposure to digital assets.
