### How Did the CAC 40 Perform on October 1, 2025?
The CAC 40 inched up by 0.3% to 7,450 points, a modest gain overshadowed by thin trading volumes. Energy and healthcare stocks led the charge, while tech shares lagged due to profit-taking. Analysts attributed the tepid rally to investors hedging bets ahead of the US budget deadline. "It’s like watching a slow-motion tennis match," quipped one trader. "Everyone’s waiting to see if Washington serves up a shutdown."

### Why Is the US Shutdown Threat Rattling Markets?
A US government shutdown—triggered by Congress failing to pass a budget—could freeze federal spending, delay economic data releases, and dent consumer confidence. Historically, shutdowns have caused short-term volatility but limited long-term damage. The 2018-2019 shutdown, for instance, saw the S&P 500 drop 2% before rebounding. This time, crypto traders are eyeing
bitcoin as a potential hedge; BTCC data shows a 15% surge in BTC futures open interest last week.

### How Are European Markets Reacting?
Germany’s DAX and the UK’s FTSE 100 mirrored Paris’s cautious optimism, rising 0.2% and 0.1%, respectively. The euro held steady at $1.08, though ECB President Lagarde’s hint at "higher-for-longer" rates added pressure. "Europe’s playing defense," noted a BTCC analyst. "If the shutdown drags on, expect capital to flow into gold and stablecoins."

### Could Crypto Benefit from Political Gridlock?
Crypto markets often thrive in uncertainty. During the 2023 debt-ceiling crisis, Bitcoin jumped 12% in two weeks. This time, BTCC’s derivatives dashboard shows traders stacking BTC puts—a bet on volatility. "Shutdowns are like crypto’s caffeine," joked an anonymous trader. "Short-term jitters, long-term indifference."
