Central banks' market backstops and leverage risk

The Reuters article authored by Simon Mugo and published on 16‑08‑2026 at 12:40 pm cites a Wall Street Journal analysis that central banks’ emergency facilities may be encouraging excessive leverage while indirectly lowering government borrowing costs. The piece notes that central banks have expanded beyond lending to distressed banks, acting as market makers of last resort during the 2008 and 2020 financial crises. Such support can halt forced selling and stabilise corporate and government bond markets, but the expectation of intervention reduces perceived risk and prompts investors to assume more debt.

Hedge funds are highlighted as a key source of concern: their US Treasury holdings rose to $2.4 trillion at the end of 2025, up from $600 billion a decade earlier, according to estimates from the Federal Reserve Bank of Dallas. These funds sometimes employ leverage of up to 100 times to profit from small pricing differences between government bonds and related futures or swaps.

Bank of England Chief Economist Huw Pill warned that mechanisms introduced to reduce financial vulnerability could create new weaknesses. He explained that central‑bank assurances that repo and government‑bond markets will remain liquid make it easier for highly leveraged investors to finance trades, and that such buying can push government‑bond yields lower, thereby reducing borrowing costs for the state.

The article describes the arrangement as working only until markets turn sharply and highly leveraged positions are forced to unwind, at which point central banks may need to intervene again. This reinforces expectations of future support and encourages the next build‑up of risk. The collapse of Treasury basis trades helped trigger Federal Reserve intervention in 2020.

Pill cited the Bank of England’s temporary gilt purchases during Britain’s 2022 pension‑fund crisis as a better model, noting that the targeted action stopped forced selling without abandoning the broader monetary‑tightening stance. The challenge, he said, is designing facilities that restore market liquidity during emergencies without providing a standing guarantee that rewards excessive risk.

The article also raises concerns that crisis programmes can interfere with monetary policy. It references the Fed’s 2023 bank‑rescue facility, which was later used by healthy institutions as a cheap source of funding, prompting officials to tighten its terms before it expired.
