Стандартная библиотека asyncio это стандарт (начиная с Py3.4) для работы с асинхронным кодом. Но эта библиотека достаточно низкоуровневая, со своими проблемами, устаревшими подходами.
Чтобы исправить это, были созданы разные обертки и альтернативы с реализацией популярных инструментов и паттернов асинхронного программирования. Это такие библиотеки как:
- trio: улучшает корректность выполнения, не оставляя потерянных корутин при ошибках, то есть предлагает Structured Concurrency из коробки.
- curio: упрощение синтаксиса и читаемости кода, больше похоже на работу с потоками.
- anyio: универсальная обертка над asyncio или trio плюс множество вспомогательных инструментов.
anyio используется в FastAPI как основная библиотека для работы с асинхронным кодом и вызовом синхронного кода из асинхронного.
В общем, рекомендую почитать про возможности anyio, возможно вы более не будете использовать чистый asyncio в своих проектах)
Это совсем не значит что дефолтный asyncio плох, он тоже даёт достаточный для работы функционал и продолжает развиваться. Например, в версии 3.11 появились TaskGroup, с похожим на trio функционалом. Так что он тоже актуален, просто придется больше написать кода самостоятельно.

Will the Federal Reserve cut rates before May 2026? 👀
Inflation says one thing. Growth says another.
Markets price probability before central banks confirm direction.
That’s where prediction systems become powerful.

🚀 Poland's Central Bank Governor: No Need for Rate Hike, Rate Cuts Paused
Poland's Central Bank Governor, Adam Glapiński, stated that there is no need to raise interest rates, and that the recent cycle of rate cuts has been paused. According to Jin10, Glapiński emphasized that the current economic conditions do not warrant an increase in rates, suggesting a stable monetary policy stance for the foreseeable future. This decision comes amid ongoing assessments of Poland's economic performance and inflation trends.

🚀 U.S. CPI Data to Reflect Impact of Iranian Energy Shock, Analysts Say
U.S. CPI data released on Friday is expected to show the first significant impact of the Iranian energy shock, according to analysts at First Citizens Bank. The surge in energy costs is anticipated to accelerate overall inflation. According to Jin10, the bank's head of market and economic research noted that while core inflation remains significantly above target, the Federal Reserve is likely to 'ignore' the energy-driven inflation spike for now. He suggested that this stance reinforces the Fed's long-term position of maintaining current rates, linking potential rate cuts to the normalization of energy prices.

🚀 U.S. Inflation Pressures Persist as February PCE Data Anticipated
The market anticipates that the U.S. February Personal Consumption Expenditures (PCE) data will indicate ongoing inflationary pressures. According to BlockBeats, consensus expectations suggest a month-on-month increase to 0.4% and a year-on-year rate holding at 2.8%, with core PCE year-on-year at approximately 3.0%, significantly above the Federal Reserve's 2% target.
Analysts highlight that the current inflation rebound is primarily driven by rising commodity prices and increasing energy costs, while 'super core services inflation' remains notably sticky, making a short-term decline unlikely.
In this context, the Federal Reserve is expected to maintain the interest rate range of 3.50%-3.75% at its April meeting, marking the third consecutive pause in rate cuts.
Market pricing has also shifted rapidly, with over 97% of traders betting on no change in April, and expectations for rate cuts within the year have cooled significantly, with mainstream views shifting towards a 'later, less' easing path.
