* U.S. banking system liquidity
Debate is intensifying around whether liquidity in the U.S. banking system is shrinking to the point that could soon pose funding, collateral and broader market risks. The Fed could soon end its QT program, bank reserves are below $3 trillion, balances at the Fed's overnight repo facility are almost zero, and usage of the Fed's Standing Repo Facility has ticked up.
Some observers say alarm bells are ringing, and point to the recent wobbles in private credit and regional banks as evidence. Others are less worried, noting that while aggregate liquidity may be tightening, it is still plentiful and the Fed has several tools at its disposal should it need them. In short, there's no cause for concern.
* Reading China's GDP tea leaves
China's headline Q3 GDP figures showed stronger-than-expected quarterly growth of 1.1% and annual growth of 4.8%, which was slower than Q2 but in line with forecasts. On the face of it, China seems to be managing to shrug off the trade tension and tariff uncertainty.
But under the surface, there is perhaps more cause for concern. House prices continue to fall, and more importantly, fixed asset investment fell for the first time ever, excluding the pandemic. An "alarming" development that points to downside risks for Q4 GDP, reckons Zhiwei Zhang at Pinpoint Asset Management.
* The importance of rare earths
Following on from that, official Chinese data also showed that exports of rare earth magnets fell in September, reigniting fears that the world's top supplier could wield its dominance over a component that is critical for U.S. defense firms and makers of items from cars to smartphones. And increasingly central to U.S.-China trade relations.
U.S. President Donald Trump said he expects to secure a "fair" trade deal with China and plans to meet President Xi Jinping in South Korea next week. Trump and Australian Prime Minister Anthony Albanese signed a rare earths deal on Monday, and Trump said he is working on deals with other countries.
