first_img Central Bank: At the end of the second quarter, the number of credit cards decreased by about 10 million compared to the previous quarter

The People's Bank of China announced the overall operation of the payment system for the second quarter of 2026. By the end of the second quarter, a total of 10.267 billion bank cards had been issued nationwide. Among them, there were 677 million credit cards and credit card loans, a decrease of about 10 million cards compared to the end of the first quarter, and a decrease of nearly 20 million cards since the beginning of the year, averaging over 100,000 credit cards exiting the market each day. Compared to the historical peak of 807 million cards in the second quarter of 2022, the number of credit cards has been reduced by about 130 million.The mid-year report of listed banks in 2026 shows that the overdraft balances of credit cards from the six major state-owned banks decreased at the end of the first half compared to the end of the previous year. The Industrial and Commercial Bank of China had a credit card loan balance of 597.157 billion yuan, a decrease of 14.39% from the end of the previous year. By the end of June, the cumulative number of credit cards issued by Bank of China was about 152 million, with an increase of 1.76 million cards compared to the end of the previous year; China Merchants Bank saw a net increase of 256,300 cards to 97.7073 million cards.In terms of asset quality, the non-performing loan ratios for Agricultural Bank of China and Postal Savings Bank of China remained at 2.05% and 1.45%, respectively; the non-performing loan ratio for Industrial and Commercial Bank of China rose to 5.37%; and the non-performing loan ratio for Bank of Communications increased from 2.68% to 3.8%. The non-performing loan ratio for China Minsheng Bank rose to 4.22%, and for Industrial Bank, it rose to 3.79%. In the first half of the year, China Merchants Bank generated new non-performing loans of 23.698 billion yuan, with a non-performing loan ratio of 1.90%. In August 2026, the principal and interest of non-performing credit card transfers amounted to 12.2 billion yuan.

first_img Kalshi and Polymarket's trading volume in August decreased by 14.5% month-on-month, marking the first decline in a year

According to The Block data panel, the combined trading volume of Kalshi, Polymarket, and Polymarket US in August fell by 14.5% month-on-month to $45.33 billion, marking the first monthly decline in a year. Among them, Kalshi's trading volume in August was $37.17 billion, down 7.3% from $40.1 billion in July; the combined trading volume of Polymarket and its US platform was $8.16 billion, down 36.7% from $12.89 billion in July.The decline in August occurred after a surge in summer prediction market activity driven by the World Cup (June 11 to July 19), but the August trading volume was still significantly higher than May's $25.66 billion. Meanwhile, Kalshi and Polymarket are facing increasingly stringent scrutiny from state-level regulators in the US, particularly regarding sports-related contracts, with more than ten states taking enforcement actions or filing lawsuits against the two platforms. Last week, Connecticut sued Kalshi, seeking to prevent the platform from offering sports contracts.Despite the escalating legal disputes with state regulators, Kalshi continues to expand its presence in the sports sector, recently signing an agreement with the United States Tennis Association to become the exclusive prediction market partner for the US Open. Additionally, earlier this week, Kalshi permanently banned former US Congressman George Santos, marking its first permanent ban, due to Santos violating rules by betting on whether he would attend the State of the Union address, resulting in a fine of over $71,000.

first_img Lighter average block proof time decreased from 5.3 minutes to about 1 minute

The decentralized perpetual contract protocol Lighter announced that its average block proof time has decreased from about 5.3 minutes to about 1 minute over the past month. This progress was achieved through two independent optimizations launched on July 23 and August 23. Lighter can now complete block verification faster, thereby increasing processing capacity, reducing infrastructure costs, and creating space for further expansion.The first optimization is the Heavy/Light decomposition. This solution splits the transaction circuit into light circuits and heavy circuits, allowing simple quote updates, which account for the vast majority of transactions, to only pay for light constraints, thus halving the proof time. The second optimization comes from the Prover backend optimization brought about by the proof competition held in collaboration with Eigen Labs, which again halves the proof time under the same circuit conditions. The first batch of optimizations went live on August 23, with more batches still in progress. Additionally, on August 10, all Schnorr signature verifications were incorporated into a single Plonky3 proof for each block, resulting in approximately a 20% improvement.The above optimizations are orthogonal and their effects are cumulative. The remaining competition optimizations are expected to bring about an additional 2x improvement, potentially reaching a total of about 10x compared to mid-July. Currently, Lighter's sustained processing capacity has exceeded historical peak loads, and the finality limit for withdrawals has been reduced from about 21-22 minutes to about 16-17 minutes, maintaining stability during peak traffic periods.

first_img Analysis: This round of BTC increase is accompanied by a decrease in OI, and spot demand has emerged for the first time

On-chain data analyst Murphy stated that this round of BTC price increase is "a bit different": the scale of futures liquidations has reached a record, but the open interest (OI) has simultaneously decreased. The price increase is mainly driven by short liquidations or buy-ins to cover positions, which belongs to the clearing of existing positions rather than new leveraged net exposure. If driven solely by liquidations, prices often show a spike followed by a drop; this time, after the surge, the price has stabilized, indicating that there are other spot funds taking over.Murphy pointed out that if the contracts are dominated by long positions, OI usually rises and rates increase, but this round saw OI decrease almost throughout, with no large-scale new leverage entering the market. The exchange's spot relative trading volume (SRV) reached 2.94 from August 19 to 20, about three times the average of the past 30 days. Similar volume increases in the past two years have mostly occurred during panic sell-offs or bull market phases, which is different from the scenarios in January when it rebounded to about $96,000 and in May when it rebounded to about $82,000, where leverage was dominant.He emphasized that the demand for spot is only a potential sign that has appeared for the first time since entering a bear market, combined with the price challenging the short-term holder cost line (STH-RP) and the seller exhaustion index entering extreme zones, it is still insufficient to conclude a trend reversal.

hot_img Blockworks: Q2 XRP spot trading volume decreased by 53%, RLUSD stablecoin supply increased by 257% month-on-month

Blockworks released the XRP Q2 report, with XRP's quarter-end closing price at $1.04, down 19.9%, and a market cap of $65.8 billion, still the fourth largest non-stablecoin asset.
