Hong Kong retail sales clock slowest growth since start of the year
Hong Kong's retail sales grew at their slowest pace since January, highlighting the impact of a global high interest rate environment.
Retail sales for September rose 13% on a year-over-year basis, less than the prior month's 13.7% rise, official data showed late on Wednesday.
"The culprit of sluggish recovery is elevated interest rates, which has been dampening consumption & tourism, external trade, and investment," said Samuel Tse, a DBS economist. "HK economic fundamentals closely follows the Mainland (China)."
Tse says external demand from both China and the rest of the world were tepid, highlighting that rising rates restrained consumption through high fixed deposits rate, a strong Hong Kong dollar and a weak asset market.

CNBC Pro: Tencent, Alibaba and more: Jefferies says buybacks are gathering steam in Asia, names stocks to watch
Analysts at investment firm Jefferies named Asian stocks primed to or continuing with significant buybacks, which they said are an opportunity for investors.
Companies buy shares back from investors for several reasons such as having a strong balance sheet and making valuations more attractive. Buybacks also provide a "sustained source of demand for equities while being a confidence-booster in terms of companies' belief in their own stock," Jefferies' analysts wrote in an Oct. 25 research note.
Several Chinese tech giants such as Tencent and Alibaba turned up on the list.

'Tighter' financial conditions may keep riskier assets from rallying, says Gina Bolvin
According to Gina Bolvin, the Federal Reserve's assessment of the economy may weigh on more volatile assets in the near term.
"The Fed acknowledging that 'financial conditions have tightened' may keep riskier assets from rallying in the short term," said Bolvin, president of Boston-based Bolvin Wealth Management Group. "So far, no change in the fed funds rate leaves fixed income and the equity market unchanged. The Fed is probably done."
After the Fed maintained interest rates at current levels, chair Jerome Powell said that taming inflation will likely require a slowdown in growth and in the labor market. "Tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring and inflation," read Wednesday's Federal Open Market Committee statement.
Stocks rallied Wednesday afternoon, to be sure, with the information technology and communication sectors leading the market higher by 1.8% and 1.6%, respectively.
