Bitcoin rose above $65,800, hitting a new high in over a month. U.S. spot Bitcoin ETFs recorded net inflows for the sixth consecutive trading day, with $203 million flowing in on Tuesday, bringing the cumulative inflow since July 13 to roughly $779 million; spot Ethereum ETFs saw a net inflow of $37.5 million on the same day, marking the third straight day of inflows. Bitfinex analysts note $68,000 is Bitcoin’s next key level, where the cost basis of short-term holders and the Q2 opening price converge. Investors who bought in the past five months and are still in the red may sell when prices return to their cost lines, so the first test of this level could trigger significant selling pressure. K33 Research Head Vetle Lunde said Bitcoin remains in a seasonal low-volume phase: as of July 19, its 30-day spot trading volume was only 62.4% of the full-year average. CME Bitcoin open interest for July has stayed below 100,000 BTC, hitting its lowest since October 2023, indicating weak institutional participation. ETF inflows have improved in the same period, but are mainly driven by BlackRock’s IBIT. Capital.com analyst Daniela Hathorn views $63,000 as the near-term support level. If Bitcoin holds above this level and reclaims the $65,000–$66,000 range, it could boost upward momentum for further tests; if it breaks below support, a new round of profit-taking may be triggered.

According to Iran's Tasnim News Agency, citing Iranian military sources, Iran has warned that if the U.S. targets Iranian bridges or power plants, Tehran will retaliate by striking infrastructure and bridges across the Middle East, including energy facilities with U.S. ties. This is a direct response to Donald Trump’s latest threat, in which the U.S. president warned Iran that for every vessel Iran attacks in the Strait of Hormuz, the U.S. would destroy one Iranian bridge or power plant. The source stated: "If vessels transiting the Strait of Hormuz coordinate with Iran and follow its arrangements, they can pass safely; otherwise, Iran will not abandon its firm will to control the strait, which it deems in the long-term interest of the strait’s security."

The Kobeissi Letter noted that tech stocks now hold a historic share of S&P 500 earnings growth. In the first quarter of 2026, Amazon, Alphabet, Meta, and Microsoft collectively contributed approximately 34% of the S&P 500’s year-over-year earnings per share growth, with semiconductor firms adding another 31%, and the rest of the index’s constituents combining for roughly 36%. Together, these two groups accounted for 65% of the S&P 500’s Q1 earnings growth—up from 52% in the year-ago period—indicating the index’s profit growth remains heavily concentrated in large tech companies and the semiconductor sector. Turning to the upcoming second-quarter earnings season, semiconductor firms’ contribution to S&P 500 earnings growth is forecast to jump 17 percentage points from Q1 to a record 48%, while the contribution from Amazon, Alphabet, Meta, and Microsoft is projected to fall 25 percentage points to around 9%. The S&P 500’s earnings growth leadership is shifting from large tech platform firms to the semiconductor industry.

U.S. SEC Commissioner Hester Peirce issued a statement noting that while many crypto assets and related activities are not subject to U.S. federal securities laws, this does not mean all crypto activities can be exempt from securities regulatory oversight. Shifting activities originally under the jurisdiction of securities laws onto the blockchain typically does not alter their legal nature. Peirce pointed out that crypto asset vaults usually use smart contracts to allocate user funds to yield strategies such as staking and lending. If a vault operator is responsible for selecting yield activities, reallocating assets, or designating decision-makers, their actions may implicate securities laws. Some vaults could be classified as common enterprises that rely on the operator’s efforts to generate profits, or fall under the regulatory purview of investment companies, unit investment trusts, and investment advisors. On-chain lending strategies may also run afoul of securities laws. Operators responsible for setting interest rates, supporting assets, loan-to-value (LTV) ratios, and liquidation thresholds should assess whether their activities are regulated; some on-chain loans may also be deemed securities-like notes based on specific factors such as transaction motives and distribution arrangements. Peirce added that the SEC welcomes vault and on-chain lending project teams to communicate with regulators. If existing rules hinder innovation, market participants can also propose amendments to strike a balance between protecting investors, maintaining market order, and facilitating capital formation.
