BlockBeats news, October 19—The core contradiction facing global markets today is that the economy still has growth momentum, but the financing costs, energy inputs, and fiscal expenditures required to sustain that growth are all rising in tandem. US FY2026 deficit has reached $1.992 trillion, with debt interest expense climbing to $1.36 trillion. Although foreign holdings of US Treasuries by market value rose by more than $83 billion at the end of August, short-term T-bill demand has weakened—indicating that foreign allocation is not fully flowing back. When the government must continuously borrow new debt to repay old debt, the risk compensation markets demand for long-term debt will directly shape the global cost of capital.
AI investment presents a similar two-sided dynamic. Economists broadly remain bullish on AI's productivity potential over the next decade, but Bank of America estimates that the weighted-average cost of capital for hyperscale cloud providers has risen from 4% in 2023 to roughly 10%, with some data-center projects also facing delays and financing challenges. Should AI investment start to cool, corporate financing needs could decline and Treasuries may regain their safe-haven function. Should high capex continue while revenue fails to keep up, tech companies and related credit markets will face stricter scrutiny on returns.
Energy and political risk add another layer of uncertainty. Street protests in France reflect that fuel, housing, and cost-of-living pressures are translating into political risk. The IEA has accelerated the release of its remaining emergency oil reserves, but this still cannot guarantee a rapid supply-chain recovery. Copper markets have likewise been affected by US tariff policy and strikes at Chilean mines—showing that energy and industrial raw material supply could still constrain the pace of inflation decline.
For crypto markets, Treasury yields, dollar liquidity, and risk appetite will be more important than any single event. Should high-yielding dollar assets continue to attract capital, BTC and other risk assets may face allocation competition. Should an AI investment slowdown trigger risk-off and drive capital back into government bonds, risk-asset deleveraging could appear first in the short term. What markets truly need to confirm is whether financing costs are beginning to depress economic demand—and whether high rates can be sustained without triggering larger financial stress.
