(MENAFN- The Rio Times) In the interconnected web of global finance, a single policy shift or diplomatic handshake can send shockwaves through markets, as seen on October 30, 2025, when Bitcoin and other cryptocurrencies plummeted.

This drop, triggered by U.S. Federal Reserve Chair Jerome Powell's cautious outlook and a tentative U.S.-China trade deal, reveals how distant decisions profoundly impact investors worldwide, including in emerging economies like Brazil.

The story begins with the Federal Open Market Committee's decision to cut U.S. interest rates by 0.25 percentage points, setting the range at 3.75% to 4.00%.

Such cuts usually fuel riskier investments like cryptocurrencies by making safer options, such as bonds, less appealing and increasing global liquidity.

However, Powell's post-meeting remarks dashed hopes: he stressed that inflation lingered around 3%, labor markets showed weaknesses, and no further cut in December was assured.



This "hawkish" tone-indicating potential pauses in easing-sparked uncertainty, eroding investor confidence and prompting a sell-off. Compounding this was the meeting in Busan, South Korea, between U.S. President Donald Trump and Chinese President Xi Jinping.

They agreed to lower U.S. tariffs on Chinese goods from 57% to 47%, in exchange for China suspending rare earth export restrictions for a year and buying more U.S. soybeans.

While a step forward, this partial truce in the trade war-ongoing since 2018 and disrupting supply chains for electronics and agriculture-was expected and underwhelming.

Trump's history of abrupt policy reversals has bred skepticism, leaving high tariffs that continue to strain global trade and economic growth.

The fallout was swift: Bitcoin fell 4.3% to $108,388 (R$582,519 in Brazil), dipping briefly to $107,000 from a recent high near $116,000. Ethereum dropped 5.1% to $3,804, XRP 6.2% to $2.48, Solana 6.3% to $187.13, and BNB 2.3% to $1,088.

The total crypto market value hovered at $3.75 trillion. U.S. Bitcoin ETFs saw $470.7 million in net outflows, led by Fidelity's $164.4 million, snapping a four-day inflow streak; Ethereum ETFs lost $81.4 million.

Analysts like Beto Fernandes point to eroding trust in Trump's consistency, while Bitget's Guilherme Prado warns that breaching the $108,000-$110,000 support could push Bitcoin to $105,000.

Beyond numbers, this episode exposes cryptocurrencies' vulnerability to central bank whims and geopolitical maneuvers, which influence inflation, supply chains, and investment flows.

For outsiders, it underscores how U.S.-China frictions and Fed policies can destabilize digital assets globally, affecting portfolios from São Paulo to Singapore and highlighting the need for diversified strategies in an unpredictable world.
